Sowjanya MV

Technical Lead at Wipro Limited

Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades

The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

Uninterrupted upgrades accelerate performance with good support

I would rate the solution eight out of ten. It should be noted that in Pakistan, some parts are not readily available, and we need to import them from Singapore or other countries. We encountered an issue with a customer where the midplane failed and was not available. We had to wait for several days for a replacement, even in a 24/7 support case. Additionally, we faced motherboard failures in the customer's environment, encountering two motherboard failures simultaneously. We obtained one motherboard immediately, yet had to wait ten days for another. These issues should have been resolved promptly given the 24/7 support level.

A solution with a simple configuration and good stability but it's quite expensive

Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

Quotes from Members

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

Pros

"As we needed to grow in capacity, we were able to do so without increasing footprint by replacing smaller devices with larger ones."

"Once we solved the data reduction and what Pure does we were hooked."

"It has improved my organization in the way that now we have lower latency, we get fewer complaints from customers, and we see a constant response time."

"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."

"Pure Storage is an amazing solution."

"They have a very good support system, and the GUI is also very intuitive."

"The most valuable features are the ease of use and support."

"The support has been very good from Pure Storage FlashArray."

More Everpure FlashArray pros

"HPE brings all of that together: Hardware, service, and support."

"The most valuable feature of this solution is the native full mesh (multi-pathing)."

"This solution has provided me with very low latency and high performance."

"The tiered storage solution they used was a lot more beneficial for our company."

"The 3PAR is very reliable, flexible, scalable, stable, and is a high performance storage solution that is easy to administer."

"It has a really powerful tool to measure data, how it is working, the performance, and if we have any bottlenecks."

"It is fast and stable. It is really helping us a lot in terms of data store, etc."

"It's a very convenient product, I find it easy to use, it's very flexible in terms of management, it's an enterprise tool, and the integration is good."

More HPE 3PAR StoreServ pros

"Latency is definitely the big key for us."

"Rocketing IOPS results in performance we don't have to fixate on, so we can instead focus efforts on other layers in the stack, knowing that our SAN layer is lightning fast, with capacity to spare."

"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."

"The ratio between the physical storage and the storage we use is very high."

"Looking at what changed at Kaminario the last couple of months (and the last couple of years, for that matter) I’m certain we’ll see a lot of great innovation from Kaminario in their upcoming releases."

"Image backups of our production servers that used to take hours now take minutes."

"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."

"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."

More Kaminario K2 [EOL] pros

Cons

"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."

"Larger capacity and more storage ports would be the two things I'd like to see."

"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."

"FlashArray could improve on the administrative side. For example, when you need to upgrade the boxes, we can't do that ourselves. We need to open a ticket with support and have them do that for us. You don't need to be on the call with them. We tell them we have a slot that we want to upgrade, and they send us an email when it's done."

"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."

"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."

"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."

"I think the pricing for Pure Storage FlashArray is the major issue because all the great things come with the price, and a lot of customers simply are not willing to accept it."

More Everpure FlashArray cons

"I want an easier solution for provisioning new servers."

"I would like to be able to deploy and manage 3PAR within OneView Global Dashboard so we do not have to use the interface for 3PAR."

"It's a little bit difficult to figure out where the capacity is used. There is deduplication that, of course, saves space, but it sometimes it's hard to find out where the space is used. If you delete something, do you get it back? So it's not very transparent regarding capacity."

"I would like to see more openness with other platforms."

"In the next release, I think I would like to see lower-cost SSD features."

"From an overall perspective, all the latest technologies can improve support and performance. This is very important for us."

"If we could do more things online for the business, it would be great."

"I would like it to be cheaper."

More HPE 3PAR StoreServ cons

"The management graphical interface needs more improvement."

"I would like them to improve the look of the product’s external casing and shelves."

"A single pane of glass to monitor/manage multiple arrays would be helpful."

"The front panel of the drive shelf doesn't always seat firmly."

"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."

"Replication and de-duplication could be better."

"Improved scale and budget planning with flexibility of the solution for budget needs and efficiency for growth with the great optimization ratio due to the nature of our use."

"I would like to see them work with Cisco, so it comes off the FIs, instead of having to go through my 10-gig network."

More Kaminario K2 [EOL] cons

Pricing and Cost Advice

"Price per terabyte is substantially higher than their competition. We would like to see it drop."

"We have seen a reduction in TCO."

"The license for Pure Storage FlashArray includes the support and there are no additional payments that are needed. This is not an inexpensive solution, you need to understand the value of your data before you use a backup solution."

"For us, as the customer, it reduced the price of the management."

"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."

"It is a more expensive solution, but it is worth it. You are getting what you paid for."

"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."

"I would rate it a seven out of ten for pricing. It could be improved."

More Everpure FlashArray pricing and cost advice

"HPE 3PAR StoreServ is an expensive solution."

"Our licensing cost are $32,000 annually."

"It is reasonable. As compared to other solutions, it doesn't seem to be much different."

"The main issue with 3PAR right now is its cost problem. Right now, there are some other storage cabinets that can do what 3PAR can do. Now, they can do it as well with a more revised budget."

"We do not have any licensing fees."

"Cost-wise, it is a little bit on the higher side, but it is an awesome product."

"I have to renew support in October for the existing solution. That will cost me roughly $50,000 this year, which in the grand scheme of things, $50,000 is not that much compared to paying $850,000. However, it will be the last year that I'll be able to get direct support from HPE. Therefore, product has to be replaced in 2020."

"Its price is a bit high for adding another tree, but when we purchased it, it was okay with us. We had compared it with EMC and other solutions, and it was okay at that point in time. Our storage has a lifespan of seven to eight years. When you purchase it, you need to keep a headroom of around 40% to 50%. After three to four years, you generally plan for an upgrade. The price is not so bad today for two years or so, and within a year, I might find that I have to upgrade or increase the storage. This usually happens when there is a radical change or a new application has come that is consuming a lot of data, but generally, there is a plan for the amount of data that we generate and the storage upgrade."

More HPE 3PAR StoreServ pricing and cost advice

"Kaminario is very competitive on price. They also have a pay per TB model."

"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."

"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."

"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."

"The licensing is all-inclusive."

"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."

"Licensing is very straightforward. The cost was considerably lower than other products we looked at."
