Dell PowerMax Reviews

We are using this solution as our main storage. We use it with VMware, as well as our databases. We are customers of Dell and I'm a team lead for network and infrastructure. 

I like the operability and easy scalability of this product. It's also easy to integrate with all of our systems. It has high speed and a good name in the market. The accounting is good, easy, be accessible. 

The solution is quite expensive and I believe Dell should examine their prices because they are currently very, very high.

I've been using this solution for two years. 

The solution is stable. 

It's very easy to scale this product. 

The technical support is good, whenever there's an issue they figured out the problem and repaired the faulty part.

Positive

The initial setup is easy; our deployment took a few days. Dell carried out the deployment for us. We have around 2,000 users in the company. 

The cost depends on the capacity that you're using so every use case will have a different price. 

It's important to think about your workloads and define them. All right. I'd also recommend comparing prices, both within and outside Dell. 

Feature-wise the solution is perfect but because of the price, I rate this solution seven out of 10.  

It's our primary storage and it replaced some older and slower storage.

The most valuable aspects include the remote replication features. It allows us to protect our data using different data centers and replicate bi-directionally between our two main data centers.

Simpler management would probably be my biggest ask. Some of the management features could be simplified and that's probably the main thing they need to address.

I've been using this product for three years. 

It's very stable.

We do have two main data centers and we have a PowerMax in each one. It is our primary storage so pretty much everything we have is on it.

We do not plan to increase usage at this time.

They need to make it easier to get to higher levels of support.

Positive

We previously used other Dell products, such as the BNXs and XtremIO. 

We switched mainly to gain access to the top-of-the-line model and we had more money to spend.

The initial setup was fairly straightforward.

It's a multi-step process. We had a hardware guy come out for a day and install it. Then a couple of weeks later, an implementation person set some things up. We slowly phased it in over a month or so.

There's not a lot of maintenance. It's usually just me, or, if I need to do a code upgrade, I just call down.

From Dell, there was a couple of hardware personnel and then an implementer. From my side, it was just me and one other staff member.

It's hard to quantify ROI for me. I'm not an accountant.

They're finally getting the licensing right where it's not a la carte so much anymore. That said, it is pretty expensive. 

We evaluated products from Pure, NetApp, and Kaminario.

I'd rate the solution an eight out of ten.

We have PowerMax 2000. It is for our clients. We have two PowerMax in our environment. One is in production, and another one is on the DR site. We have to replicate the data from production to that one.

It is important for our clients that PowerMax provides NVMe scale-out capabilities. They are also getting great performance as compared to the old storage array model. 

Provisioning is faster and immediate. We can do immediate allocation and configuration. As compared to the old storage array model where it used to take half an hour, in PowerMax, we can do it in 5 to 10 minutes. It doesn't take that much time, and there isn't much delay in the PowerMax array.

Our workload is reduced because we are not dealing with any issues. We are not facing many issues on the PowerMax side as compared with the previous one.

Based on our experience with VMAX, there isn't any hardware failure or something like that in PowerMax. Performance-wise also, everything is fine. We haven't faced any performance issues or any hardware failure. Its performance is great as compared to VMAX. Its I/O per second rate is higher than the old model.

We can use it block-wise, and we can also use it at the file level. It is good for any environment.

I would like to see more development in the cloud environment. It would be good if it comes in the cloud kind of setup. 

I have been using this solution for two and a half years.

It is very stable. It has very few failures. In the last two and a half years, there is only one failure that I have faced in PowerMax. That was because one of the ports went down. The port was replaced within two days or something like that by an EMC engineer. Hardware failure is very rare in PowerMax. Previously, in VMAX, multiple drives used to fail within a day itself. 

In our setup, we are just using less than one petabyte. In the PowerMax itself, we are using 130 or 150 TB. For scalability, it is the best option. We can directly connect the PowerMax array with the other storage array devices, such as a USB, without any performance issues.

We don't have much involvement in it. Whenever the customers need any help, they ask for some help from our side, and accordingly, we provide the help. They usually involve us only when they have any doubt. The entire configuration is done by EMC itself, so we are not a part of the implementation.

We don't have any involvement in the pricing. We are just from the backend support team for the PowerMax array. If any expansion is required, we will just inform the customer, and the customer directly contacts the EMC person. They discuss and finalize the dealings, and we are not involved in those dealings.

It is a good solution for any environment. You won't face any issues in terms of performance and stability. 

SRDF has helped to reduce storage costs, but I can't provide the numbers. We don't handle that aspect. We are from the support team, and for capacity, there is a separate team in our environment. That capacity team takes care of the capacity and does the daily basis and monthly basis kind of calculation. We are just supporting the existing environment, and we have to maintain its availability.

We have not been able to consolidate open systems, mainframe, IBM block, and file or virtualized data with cloud-connected storage using PowerMax. That's because currently in our environment, there isn't a separate cloud, and the cloud is not connected with this PowerMax.There is also no mainframe server. We have a separate storage array for IBM in our environment. Similarly, EMC is also separate.

We have not used PowerMax's NVMe SCM storage tier feature and PowerMax's built-in QoS capabilities for providing workload congestion protection. We have also not used PowerMax's Metro Smart DR, also known as MetroDR.

PowerMax would be useful for enterprise-level storage or mission-critical IT workloads, but in our environment, we only have the basic model, which is PowerMax 2000. As per my understanding, it will be good and useful for mission-critical applications.

I would rate it a nine out of 10. I am not giving it a 10 because day by day, technology is improving, and there might be another solution that is better than this. Even EMC might find another solution and introduce it.

We are using it for core banking systems and virtualized enrollment. So, everything for this bank is on PowerMax, including its core banking system, which is running on Solaris, and all the relevant applications running on VMware.

You can use PowerMax for all workloads and consolidation. We have used it to scale thousands of VMs. This is Dell EMC's selling point. 

It is a good, resilient product.  

The good thing that we have found is the enhanced data savings. For example, in an XtremIO, we were seeing the space savings was 1:4 or 1:3. With PowerMax, I have seen 10:1 and 12:1. This is something that has really come out as a distinctive feature and is helping us a lot.

The Unisphere GUI has been enhanced. A lot of options have been added to the GUI. Though, if somebody is planning to buy PowerMax, they should also have some associated training with that.

We brought up this question to the implementation engineer. We were comparing use cases where a customer is using RecoverPoint, then goes to PowerMax. In our previous setup with XtremIO, we were using RecpverPoint and keeping snapshots for 30 days, every few seconds. With PowerMax, I requested this for every 15 minutes, keeping it for a week. The engineer's answer was, "There will be too many snapshots. It might slow down the system." This is specifically for the use cases where there is RecoverPoint. While PowerMax works with RecoverPoint, and you can use it, there should be some way where you can have even more snapshots and not to worry about performance and system cache.

We have been using PowerMax for less than a year. We just installed it recently.

From my experience, it is stable enough. For our current setup, it is too early to assess stability.

They support scalability. We can add more capacity when it is needed.

I always tell my customers that Dell EMC support is good. Specifically with enterprise storage, like PowerMax and VMAX, it is really good.

Positive

PowerMax was deployed as a replacement/tech refresh for our existing VNX.

We were using XtremIO before this. We have all of the features that were available there. Relatively, there is nothing new that we are using.

We had some challenges with our core banking system. There were performance issues, which was the reason we went to XtremIO All-Flash. NVME has really helped us here because anything less than XtremIO would have caused us issues. So, PowerMax is the best replacement or fit right now. In fact, we have seen that it has really improved the performance as well.

The initial setup was straightforward.

We are still in the implementation phase. 

The ease of administration is okay for me. However, for other team members and specifically our customers, who are not very familiar with it. It has increased provision time. Though, it is just a one-time activity. During implementation, we did the split properly. Therefore, there will not be challenges going forward. 

Initially, it took a lot of time to do the initial provisioning, specifically for the Dell EMC engineer who provisioned a couple of hosts. After that, we did all the provisioning, SRDF replication, snapshots, scripting, etc., and that took awhile. 

I am hoping that this is just one time. Going ahead, it should be simple to add volumes and not have to go through the cycle.

Implementation was mainly done by a local resource, because we are not a deployment partner. The resource connected to somebody remotely from a site in Egypt. We managed to deploy it in half a day for each site. The first time that we did the provisioning, it took time, but it was a relatively straightforward process.

We had some requirements, like SRM integration, where we needed some guidance. Dell EMC has suggested that we use CloudIQ, so we want to explore that option. However, we are not using it right now.

We have used VMAX in other places. It has helped because it has various options for data protection. I have worked on DMX3, DMX4, and VMAX 10K. I am a fan of VMAX because it is really good. There are various command line options that allow you to do a lot of things.

Most of the products are the same and have similar features. There could even be some which might be better. However, one thing that I always liked about Dell EMC is the support, which is really good. If there is an issue and you can get somebody to resolve it, that is the most important thing. Many products have the same features, e.g., snapshot, replication, and data compression, but the support from Dell EMC is one of the best.

It is a good enterprise-scale storage. I would rate it nine out of 10.

Generally, storage doesn't expose your data unless you have certain protocols. With PowerMax, it is too early to remark on data security because we just deployed it and migrated the data. We have not even done a proper drill or failover for data availability and data security. 

It is also too early to remark on workload congestion. Though, since we have been migrating the data, which is live data, I have seen the utilization and that is performing relatively better than our previous Dell EMC platform.

From a technical perspective, you should have some technical training associated with the deployment. That is the one aspect that is complicated. Apart from that, everything is simple. 

We use it for our core banking data.

It has improved storage I/O for our big apps and restores. And the snapshot process and data compression are better.

We like the compression, dedupe, and I/O on the PowerMax. They are better than on the XtremIO.

Snapshots make it easy to deploy production, pre-production, and UAT environments. It is easy to snapshot and reverse snapshot to other environments, compared to other storage vendors.

In addition, we have a lot of users in our core system and the PowerMax performance is very good. The I/O performance is running fine; it's not an issue.

We would like more documentation, a guide to the features of the PowerMax. We needed to use the option to reclaim storage and we had to chat with the Dell EMC team.

We have been using Dell EMC PowerMax NVMe for around one year.

It is stable.

Because we have just started using it, we haven't scaled up yet.

We have opened cases with the Dell EMC team and we have chatted with them. They have provided good, fast support for us. But in some cases they did not explain the solution well.

Positive

We used XtremIO. We switched because we found many of the features and the functions are better on the PowerMax than they are on the XtremIO. An example would be the snapshot. When we would do snapshots on the XtremIO, we could delete a snapshot, even when we were mapping to the host. But with PowerMax, we cannot delete a snapshot when mapping to the host.

The setup was difficult because PowerMax has more functionality, but some of that functionality is still not clear to us.

Four people work with it on my team; all system admins.

PowerMax is a good storage solution for the banking sector. Choose it for your core banking system, because of the dedupe and compression, the I/O, and the high availability for your data.

We are the centralized IT department for a state government and we service every agency in the state. That includes anything from the state police down to DNR, parks, unemployment, and DHHS. There is a wide variety of use cases, but the big hitters on it are Oracle and SQL databases.

It's on-prem. It's in two different data centers that are 60 miles apart and we're doing a synchronous replication between the data centers.

There are so many ways it has helped. It provides efficiencies through compression and it provides high availability through its solid-state drives. We literally turn it on and it does its thing.

When it comes to storage provisioning, a lot of it has been automated. This was true even prior to PowerMax, back with the VMAX. The days of provisioning the mapping and masking, and doing all those things manually, are over. A lot of that is automated through their tools. Overall, that automation is saving us about four hours a week.

What is most valuable to us is the fact that it has multiple engines, and each of those engines works in conjunction in a grid environment. That's important to us because we have so many different use cases. One example might be that a state trooper pulls someone over at 2 o'clock on Sunday morning and wants to go into the LEIN system, which is the law enforcement information network. He wants to see who this person is that he has pulled over and gather as much information as he can on that person. We can't predict when he's going to pull someone over, nor can we predict when backups are actually going to be taken against the volume that he's going to for that information. The PowerMax allows us to do backups of that volume at the same time that he is looking up the data he needs, and there's no impact on performance at all.

The performance is very good. Our predominant workloads are all less than 5 milliseconds and it's most common to have a sub-1-millisecond response time for our applications. In terms of efficiency, we've turned on compression and we're able to get as high as two-to-one compression on our workloads, on average. Some workloads can't compress and some can compress better, but on average, we're a little bit more than two-to-one.

The solution’s built-in QoS capabilities for providing workload congestion protection work pretty well because we actually don't even turn on the service level options. We leave it to the default settings and allow it to decide the performance. We don't enforce the Platinum, Gold, or Silver QoS levels. We just let the array handle it all, and it does so.

We also use VPLEX Metro, which is a separate service offering from Dell EMC. It does SRDF-like things, but it's really SRDF on steroids. Of course it copies data from one data center to the other, but with the VPLEX, not only does it copy it synchronously, but it also has coherent caching between both data centers. That means we are literally in an Active-Active mode. For instance, we can dynamically move a VMware host that is in one data center to another data center, and we're not just doing vMotion with the host. The data is already in there at the other data center as well. It's all seamless. We don't have to stop SRDF and remount it on another drive. It's already there.

We have been using Dell EMC PowerMax NVMe ever since it was brought to market, so it's been about three or four years.

It's rock-solid with 100 hundred percent uptime. We've never had a disruption on our PowerMax platform. It's high availability. And we can make changes, such as upgrading the code, while it's running. There's no such thing as going offline to do a service or maintenance procedure. It's all done online and the customers are working away at the same time.

The scalability is great. VPLEX is something like a federation for all our PowerMaxs. We will put a PowerMax in, give it all to VPLEX to manage, and we're good to go.

We typically see a 10 to 20 percent growth rate, year to year. To keep up with that, in a multi-petabyte environment, 10 percent is quite a lot. We buy two a year, and that's a conservative estimate.

The fact that PowerMax provides NVMe scale-out capabilities is important from the standpoint of its internal workings, but the customer data doesn't really go on the NVMe technology. At this point, we don't have any use cases for NVMe performance for any of our applications. But that will change in the future. Everything is going to go to in-memory. Compute and storage: everything's going to be on a chip.

Their technical support is really good. We are using one of their monitoring tools and it phones home to the "mothership" in Massachusetts. That means they get real-time alerts or performance indicators. If a drive has exceeded a threshold five times in the last week, they will actually come out and preemptively replace that drive before it fails.

We were a VMAX customer, so when they changed their service offering from VMAX to PowerMax, that's when we started adopting it. In a sense, PowerMax is the first of its kind for us. But we have been a long-time customer. We started with their DMX almost 20 years ago.

For us, it's straightforward to set up. We've been doing this for a long time, so it's really easy for us to set up a new array in a data center. We had one that hit the dock about two weeks ago and it's already up and running and provisioning to customers. 

NetApp will say, "Well, that's two weeks. We can come in and do it in one day." But we explain, "No, you can't because there are internal processes that we have to go through." Every piece of equipment we get, even the PowerMax, goes through its paces. We don't just turn it on and hope for the best. We check and double-check all our configuration settings. But overall, PowerMax is easy to set up. They configure it at the factory, deliver it, put it in the data center, and then we hook it to our Fibre Channel fabric and Ethernet fabrics and we're good to go. Competitors will say, "Well, it's so much easier to migrate from one array to another on our platform, versus the Dell EMCs." That's not necessarily true. We have to look at what they are actually measuring and whether we are comparing apples to apples.

With VPLEX, we can do migrations on-the-fly, live. It's no longer a six-month to one-year effort to get off of one array and move to another. We just bring the other array in, present it to VPLEX, and VPLEX takes it from there.

For a new deployment of one PowerMax, we need one FTE. On a day-to-day basis, to manage all of our PowerMaxs, we need three FTEs. But that is across two different data centers with a total of 10 PowerMax/VMAX units. It's a pretty big installation. Across our organization we have 55,000 employees. Since our HR is on this solution, and that's how people get paid, it's like we have 55,000 people using it, in a sense. Most access is through an application, but in another sense, it's used by pretty much everybody in the state.

On a typical purchase, the ROI is four years. That's when we get our money back. We charge for our service and we have a rate per GB. Our business model is set up to only recover our costs because we're government. We can't make a profit on it.

One area for improvement, one that everybody always comes to, is price. Although we get a good discount through Dell EMC, it's still quite expensive to purchase these big arrays. I buy in volumes of petabytes at a time. It's not unusual for me to have a $6 million spend. While that is petabytes of data, it always raises eyebrows when you spend that kind of money. But what I ask those raised eyebrows is, "Okay, fine. Which of the agencies in the state do you not want to give more storage to? Everybody's using it."

Many competitive vendors will come to us and say, "We have a study where we went into a company and we were able to reduce their costs by 600 percent." Of course, these are salespeople and they're speaking to two levels above me, and they buy into that and say, "Yeah, let's have them come in and talk to us." They come in and talk to us and when we get to the stage where we say, "Here's a typical configuration. Give us a quote for that type of configuration." When we compare it to the cost that we're getting from Dell EMC after the discount, it's plus or minus 5 percent. There really isn't that big of a delta compared to our pricing. This is a high-end device. For us, the pricing doesn't make Dell EMC uncompetitive.

NetApp and Pure Storage are the biggest ones we looked at for block storage. 

For other storage, like file, print, and object , there are a dozen others that are always trying to differentiate themselves on price. They want to do a proof of concept and we do those with them. But what I'll tell them up front is, "I know your products are great. They're going to work great in our lab. You don't really have to send me a piece of equipment for me to test it. I know it's going to work. You guys wouldn't be in business if they didn't work. So let's get down to the cost of it." And when we get to the cost of it, it's just not compelling enough to make a switch.

But as far as features go, I don't find there is a huge difference.

The biggest lesson I've learned using PowerMax is to trust it. For example, with the QoS, don't try and overthink this. It's engineered to take on diverse and disparate workloads. Put it in, watch it for a little bit, and if you don't absolutely need to turn on all the QoS, don't. Let it do its thing.

Don't be shocked by the price per GB. Look at your cost of transactions or IOPS. The days of looking at storage as so much per GB are over. It's how much workload you can pass through that storage device.

Overall, PowerMax is ideal for storage for enterprise-level, mission-critical IT workloads. That is really its strength, as is its ability to handle disparate workloads. I wouldn't use anything else for these high-end, critical workloads.

The uptime is the most valuable feature, and we are satisfied with the solution.

We have been using this solution for five years and are using version PowerMax 2000.

It is a stable solution. 

It is scalable. 

The technical support is very good.

The price could be lower, and we are unhappy with the price. The licensing cost is included in the hardware price, so I am unsure if there are other licensing costs.

I rate this solution a nine out of ten. When we bought it, we accepted the high price, but five years later, we need to reevaluate before we buy the next generation.

The best feature is the protection - PowerMax NVMe is volume-based and replicates data, so it's very comfortable for us to use.

The GUI interface is very complicated and could be improved by streamlining the number of steps in the process, as the new storage UIs have done.

I've been using this solution for eight months.

PowerMax NVMe is stable.

This is a scalable solution.

I'm happy with Dell's technical support - we have a private support contact that ensures we get good support.

Positive

I would rate PowerMax NVMe six out of ten.
