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.

Storage solutions accommodate diverse drives and offers good resiliency

Technical support is good. I can log complaints online through the portal and have engineers in line. I can also take dedicated engineers if needed, although this involves a different support cost. As far as my requirements are concerned, it is working fine. There are two or three types of support. Standard support involves logging a complaint and receiving a call from the OEM on the same day, but hardware replacement takes two to three days. Advanced support offers instant replacement without delays. Hardware support terms include calling or emailing the company or logging the call in the portal to receive remote support, or getting a dedicated engineer or account manager from Dell.

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 mobile app is very helpful."

"It benefits our IT organization in the way that it's easier for the administrators to manage."

"Support has been helpful."

"I can personally state that the Pure Storage Flash Systems are the best built and Pure has the utmost professional customer care."

"Lone segmentation is simpler and more agile. It's improved the velocity in overall provisioning from project to operation."

"It overperforms both in terms of storage capacity and throughput, and bandwidth capability."

More Everpure FlashArray pros

"I think that Dell EMC is one of the best technical support services in Ukraine."

"The solution is stable."

"The most valuable feature is the speed for the end-user."

"This solution is easy to use."

"The solution has a wide variety of valuable features. The data progression works well. We use the snapshot functionality quite a bit and really like it."

"It has been one of the most stable products in our data center."

"Technical support is really good. We have had good, high-quality support with our SC Series."

"The flexibility of this solution has been valuable for our business."

More Dell SC Series pros

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

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

"I think this product hits all the big features of all the SANs that are out there, all the storage vendors that are out there and more."

"So coupled with the simplicity, performance, and just absolute ease of use of the management of it, I don't know why anyone wouldn't buy it."

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

"Technical support is absolutely great."

"Ease of use: My installers - my administrators over the system - they love how easy and fast it is to install and spin up a LUN and get going."

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

More Kaminario K2 [EOL] pros

Cons

"When it comes to Everpure FlashArray ports shown in the GUI, it would be better if, when one of the Pure array ports went down, there was a possibility to highlight that particular port which has gone down."

"Pure Storage FlashArray has not helped to decrease the total cost of ownership, and I believe our total cost has probably gone up, but that's balanced by our increased amount of data and number of use cases."

"We have not seen a reduction in our TCO nor have we seen ROI."

"The price of this solution could be improved."

"I have been primarily working with storage and have not fully explored other areas, but there is some room for improvement when it comes to performance reporting."

"It needs to improve its price."

"From a scalability perspective, it is a very small storage solution, so it's not very expandable."

"Automation could be simplified."

More Everpure FlashArray cons

"They need to make it a little cheaper."

"To begin with, we were ready to throw it out the window."

"We had some issues with the battery in the previous version that we were unable to resolve."

"If Dell SC Series could have supported the protocol NVMe over TCP, that would have been great. It does not."

"This system is not a good fit for most customers. It's not only the fact that it's too old, but it has not developed any more since Dell bought it."

"While there's always room for improvement in everything, I can't really think of a specific feature of the solution that requires immediate attention."

"The lower model, the 3000, should have duplication. It doesn't right now. It's only from 5000 that this is offered, but it depends on the performance. It could be they don't offer it on lower models because the duplication is too much of a burden to the performance."

"In terms of additional features, I would like to see some kind of I/O meter, to indicate what we are using in terms of performance. I would like to see automation with that, where it would give me the trends. I want to know those things easily, to help me know where issues are going to occur."

More Dell SC Series cons

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

"I would like them to come down in price."

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

"There are a few areas where the system could be improved. Examples would be that the system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."

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

"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."

"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."

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

More Kaminario K2 [EOL] cons

Pricing and Cost Advice

"The price is reasonable."

"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."

"The Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again."

"Because of the SSD, it is cheaper because I am not purchasing so many disks."

"The price is too high."

"There are no licensing fees or other costs."

"Pure Storage has not helped us to reduce our licensing costs."

"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."

More Everpure FlashArray pricing and cost advice

"The SC Series was priced fairly. I wouldn't call it either expensive or cheap because we had a very tight budget, so if they were able to fit in that type of budget, they met our expectations."

"This solution could be better priced in comparison with other vendors."

"It's absolutely affordable. Again, not having to do a forklift upgrade like some of the others have had to do in the past, it's very affordable for our customers and they continue to buy."

"The pricing of this solution is competitive."

"It is one of the most cost effective systems for us. We have been able to run it longer than most, getting the most benefit and money out of it."

"We were able to afford two tiers of flash storage at a price where the competition was giving us one tier or just a handful of discs."

"The pricing of Dell EMC Compellent is competitive."

"The scalability seems a bit more expensive than even buying a brand new one so far. That has been kind of a drawback."

More Dell SC Series pricing and cost advice

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

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

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

"The licensing is all-inclusive."

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

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

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