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.

"The most valuable feature is its speed."

"Now they are trying to add more and more applications because they're getting better performance and stability."

More Everpure FlashArray pros

"With so much technological advancement and more coming, the world is their oyster."

"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."

"Tegile All-Flash Storage Arrays deliver maximum performance, high density, compelling economics and it is ideal for latency-sensitive, business-critical workloads such as online transaction processing, real-time analytics, decision support, and data warehousing."

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

"The initial setup is straightforward."

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

"It performed great originally, and when it performed great, it was awesome."

"Ease of Use: Someone can learn it in only few hours Performance: Easy Tier is doing miracles Data Compression: Up to 80% space reduction in the database"

More DDN IntelliFlash pros

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

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

"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."

"The GUI is very straightforward and easy to use."

"Improved performance by more than 50x on our application."

"The most valuable feature is definitely the always-on data deduplication."

"Kaminario allowed us a solid state solution with marginal incremental cost."

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

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."

"We would always like to see higher performance, and lower pricing is always better."

"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."

"Pure Storage FlashArray could improve in the area of cryptographic information in the consoles. The user-friendliness could improve. The Pure Storage FlashArray team should come and log into the system with their maintenance credentials and then pull out the information as evidence of cryptography."

"Everpure FlashArray can be improved as the pricing is expensive, but you do get what you pay for; you are paying a premium for better service, better warranties, less downtime, and other things, so I do not know that a lower price would work out because you probably would not have that high of quality for those things."

"Pure Storage FlashArray has not helped decrease the total cost of ownership."

"Scalability is not an easy option for Pure Storage, so you have to be very careful when you are getting that product for you."

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

More Everpure FlashArray cons

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."

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

"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."

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

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

"The monitoring matrix and its dashboard need work."

"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."

"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."

More DDN IntelliFlash cons

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

"I'd give it a perfect rating if I could push it to 300,000 IOPS like they promote; we just haven't been able to push that many IOPS out of our system."

"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."

"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 them to come down in price."

"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."

"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."

"Replication and de-duplication could be better."

More Kaminario K2 [EOL] cons

Pricing and Cost Advice

"We purchased a license to use this solution and we pay for the storage ourselves."

"Cost-wise, it's been very effective."

"We have seen a reduction in total cost of ownership (TCO)."

"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."

"All storage is expensive so any price improvement would help."

"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."

"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..."

"The pricing is reasonable."

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."

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

"The licensing is all-inclusive."

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

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

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