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.

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

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

"The support team is available all the time and they seem to know what they are doing."

"The speed is the most valuable feature of this solution."

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

"The white glove customer service that I get is their greatest value."

"The most valuable feature of Pure Storage FlashArray is its high stability level."

"The best features of Pure Storage are their support and analytics."

"I appreciate the ease of provisioning storage on Pure Storage FlashArray."

"While all these products have their own uses, Pure Storage FlashArray is in a market of its own."

More Everpure FlashArray pros

"After five years, the cost decreases over 30% and the performance increases over 50%."

"Once we got this solution in there, we were able to get the reporting down from eight hours to under 20 minutes."

"We have been able to realize storage space savings for our virtualization environment and it has reduced our electricity usage by reducing the number of disks needed for the virtual environment."

"It has cut batch job runtime in half, so we're seeing performance improvement throughout the organization."

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks Cheaper than pure solid state without needing to actively manage where the data is located."

"Data Compression: Up to 80% space reduction in the database"

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

"It provides a combination of all the protocols that you need, without losing deduplication and compression."

More DDN IntelliFlash pros

"Logic/software management"

"The stability of the solution is very good."

"Our holdup was disk I/O, so we did a PoC with Kaminario and we reduced build times down to fifteen minutes for a full build from two hours."

"The K2 has basically removed storage as a bottleneck in our datacenter."

"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."

"Technical support is absolutely great."

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

"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."

More Kaminario K2 [EOL] pros

Cons

"The capability from Pure as far as sharing out files and things of that nature is a little bit lacking."

"Once, before Pure went public, we were a member of their customer advisory board and beta tested replication. One requested enhancement yet to manifest is the scheduling of snapshot replications."

"Its price needs improvement. Its price is almost double than any other flash storage solution."

"For scalability, I rate it a six out of ten. We reach a limit. We never reached this limit, however, the architecture allows you to go until a certain size, and after that, you have to buy another array."

"It falls far short of protocol support."

"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."

"A noticeable area for improvement is the support for object storage."

"I would like FlashArray to add reports that help us forecast our predicted resource needs based on current usage."

More Everpure FlashArray cons

"Snapshots are not as easy to access as on a NetApp device."

"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."

"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."

"In future releases, I look forward to more AI features."

"It's annoying that if you turn on SMB3 (as opposed to the earlier CIFS protocol), then it is not possible to access a file store using a mixture of SMB and NFS."

"It only keeps one hour of real-time data without the ability to do deep analysis of each element."

"The solution as it is right now is not very stable. The stability seems to have eroded."

"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."

More DDN IntelliFlash cons

"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."

"The management graphical interface needs more improvement."

"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."

"What I think would be a great idea for Kaminario is more visibility outside the US, when my customers start talking about AFA I notice they almost never talk about Kaminario, mainly because they just don’t know about them, and there are no local sales team to tell them about the Kaminario offering."

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

"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."

"On the road map, I'm hoping to see Active Directory integration. Right now, you still have to use a local admin account to log in and manage everything."

"The interface look and feel could be improved."

More Kaminario K2 [EOL] cons

Pricing and Cost Advice

"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."

"The price of the solution can be a bit expensive. There is an additional fee for support."

"We do not incur additional costs beyond the licensing fee."

"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."

"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."

"Our costs are around $100,000."

"You can pay extra for Evergreen support, which gives you free upgrades when new features are introduced."

"You get what you pay for. It is expensive, but it really works."

More Everpure FlashArray pricing and cost advice

"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."

"I think we pay around 100 grand per year for three arrays or four arrays."

"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."

"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."

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