Helps to save money and resources with the data compression feature

One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Seamless management and exceptional performance facilitate efficient data handling

I have not faced significant problems or challenges with Dell PowerMax NVMe during this time, although one area for improvement is its user-friendliness, as it's a bit engineer-oriented. Specific knowledge and expertise are required to manage it properly, which some users might find a bit challenging, yet it's not a big deal for me. With user experience in mind, an improvement for Dell PowerMax NVMe could be clearer total capacity measurements from snapshots and clones, which should be more visible for better planning. Additionally, a template script from PowerMax could assist customers in easily integrating their API-interconnected systems without needing extensive knowledge. To improve regarding scripts, I recommend that if a customer wants to automate snapshots from other systems, Dell can assist by providing plug-and-play integrated templates that allow customers to drag, drop, modify, and connect with any target system for generating snapshots without logging into the storage directly.

Efficient data replication and fast IOPS have improved operational performance

Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"One of the best features is the support, which is excellent."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"The latency is good."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"The high availability of the product is the most valuable feature."

"The most valuable feature of this solution is its ease of use."

More Pure FlashArray X NVMe pros

"We are happy with the monitoring that Dell EMC is doing for us. They have helped us to identify many issues during the routine checks, issues which we were not aware of."

"It is easy to manage and upgrade."

"A huge benefit of the PowerMax has been the decreasing of our physical footprint. We recently did a consolidation where we went from 58 tiles down to 5. If we had used just the PowerMax, we could have gone from 58 tiles down to 2 tiles, which is huge space savings. If you have 56 newly available floor tiles on a raised floor data center, which you previously had to cool and provide power to, then now, not only are my costs going down, I now have more revenue opportunities because I have more space to put new customers."

"We find the service level option to provision storage very valuable. The ability to define different service levels for storage groups helps us in prioritizing our workload at the infrastructure level."

"I am impressed with the tool's reliability since we see a few hardware failures with it. Also, the solution's replication configuration is good."

"The performance is very good on our servers. It's superior. And the QoS capabilities for providing work congestion protection are also important because about 99 percent of our servers are production servers."

"Dell support for Dell PowerMax is exceptional, rating a perfect 10 out of 10."

"The solution's technical support was good, and it is one of the tool's main advantages."

More Dell PowerMax pros

"It has reduced complexity."

"It has the same operating system for both file and block, and it actually simplifies everything. And it's much smaller compared to VNX."

"It has made deployment, configuration, and maintenance a lot simpler."

"The multiprotocol support. It's supporting NFS, fiber channel, CIFS, and these kinds of things. The multiprotocol is very attractive."

"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."

"They've integrated NAS and SAN pretty well. It made replication very simple. Because one of our systems has a lot of LANs, for it to replicate we have Consistency Groups in there. That's something that is really helpful, making sure that everything is working not just for replication but for backups as well."

"We put the Unity on one of the file servers and the backup performance improved quite a lot."

"One of the things that I like the most about it is how they have changed the Unisphere GUI, and how it is now HTML5. It is so easy to use. Also, the array itself is so simple, easy to set up and easy to use, but it still has that great Dell EMC technology behind it."

More Dell Unity XT pros

Cons

"Adding some functions to the product would be beneficial."

"We need better data deduplication."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"Maybe the price can be reduced since the solution is very expensive."

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

More Pure FlashArray X NVMe cons

"If the solution had more power-saving capabilities, it would be quite nice."

"The disadvantage of PowerMax is its cost."

"Support of the product can be slow and an administrative challenge: planning, scheduling, and overseeing data center access for a Dell EMC rep. One improvement could be to enable a self-maintenance option. The requirements that we go through to get Dell EMC onsite to replace failed drives, power supplies, and other small redundant parts can be unnecessarily complex. If simplified, they could send us the parts, then we could replace them much faster, more easily, and truly within the SLA parameters."

"We are very interested in NVMe over Fibre Channel, which I understand is on the horizon. We would like to see that come to fruition."

"The one area for improvement in Dell PowerMax NVMe would be to align the features of the on-premises version with those available in the cloud, as this would provide added value and flexibility."

"There are some stability issues that we just recently experienced. We hope the next release will solve these problems."

"Dell PowerMax or Symmetrix is a block-level storage and unified storage, supporting both NAS and SAN. One area for improvement would be integration with public cloud services."

"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."

More Dell PowerMax cons

"Maybe deduplication would be something that would be better to have. Also, it's a fairly new management interface, so work is still being done on that. But compared to other vendors and previous EMC storage, the Unity is really good."

"It could go faster. Make it bigger, better, and faster at a lower price, and I am there."

"Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things."

"The initial installation is straightforward and took approximately one hour. However, the full process was not as simple as IBM."

"The user interface could be improved. The Dell Compellent user interface is fantastic, but the Unity user interface is, in comparison, pretty lousy. It's functional, and I can do what I need, but the Dell Compellent user interface is so much more intuitive and user-friendly."

"It would be great if the solution could integrate an NVMe disk."

"In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance. I think that could be improved, because everything should be included in the product, not with an appliance from the outside."

"It's very frustrating that it's not backward-compatible with the previous platforms, so it's a struggle for a lot of our customers."

More Dell Unity XT cons

Pricing and Cost Advice

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."

"With VMware, we pay $300,000 annually."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

"The licensing is on a yearly basis."

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

More Pure FlashArray X NVMe pricing and cost advice

"The price is really high."

"The pricing is competitive. I would rate the pricing of the solution a six out of ten."

"I rate Dell PowerMax NVMe a five out of ten for pricing."

"The pricing for this solution is good compared to other products in the market."

"The tool is very expensive."

"Dell PowerMax NVMe's price is expensive."

"The pricing is comparable to other vendors."

"It is high-end storage and it is a bit expensive, but it is doing what it is meant for: running business-critical applications or latency-sensitive applications..."

More Dell PowerMax pricing and cost advice

"From a pricing perspective, this solution is comparable to others on the market."

"Its biggest valuable feature is its price point for the amount of storage and performance you get. It's a sweet spot. It's cheaper than the other SANs out there, but performs well enough. It fits that nice, middle-ground portfolio."

"This solution is a good price for what you get."

"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."

"It was easy to order. We are a big Dell shop, so it was easy to purchase and get it in place, then up and running."

"Licensing is a little bit confusing. Going through everything with them, there are a lot of line items to go over. Every single thing is broken down into a line item, and it starts to get really confusing in terms of what we're actually purchasing when it comes to the product."

"We purchased a five-year warranty."

"When I see other products—like HP, Huawei, and Lenovo—from competitors, I have seen a lot of disadvantages with EMC, price-wise. Huawei and Lenovo are very price competitive. Looking at the price point for a country like Sri Lanka, where we have a very low economy, I think you need to look at a pricing mechanism that is a bit more flexible."

I have used all, EMC, and HPE 3Par, VNX, Unity, etc. All are OK. But for long term Flash Storage, I would take a look at Hitachi F Series. Best reliability hands down and they provide non-disruptive migrations, no server downtime, no scheduling with users, etc. NDM makes Hitachi a no brainer.
