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.

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

"We consume less physical storage because of the solution’s deduplication and compression."

"For me, right now, it is the best storage solution in the market, by far."

"The compression and deduplication features help to make the best use of the capacity."

"For an organization, it can take storage from 40 terabytes down to five terabytes."

"From the first test that we have conducted, we are very satisfied with this solution."

"The most valuable feature of the Pure Storage Flash Array is the blazing fast monitoring."

"Their technical support is excellent. It's the best out of any of the vendors we work with."

"I would recommend Pure Storage, as it is well-established."

More Everpure FlashArray pros

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

"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."

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

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

"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."

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

"Logic/software management"

"It has a very good duplication rate; very, very good."

More Kaminario K2 [EOL] pros

"Greater IOPS, speed, it's all-flash. So seeing that everything is going to all-flash, all SSDs, SolidFire fits right in there with the emerging trend in IT."

"The system efficiency is excellent overall."

"If you're bring up cloud in-house and you're still not aware of OpenStack Kubernetes, that's the way ahead."

"Provisioning times have gone down and a lot of the random errors from different things that we've seen across time kind of all went away."

"If we get complaints about any kind of performance metric issues, whether it's storage related or something on the virtual side, we use it to pinpoint what the actual issue is."

"Templates are already predefined for it. If you're coding it up, it will take two days. You can pick up a template right there from the API, and it just works for you. Implementation done in 10 minutes."

"We can just buy them, scale them as we need on demand, and we don't have to spend so many front end cycles on designing the architecture."

"Overall performance of the solution."

More SolidFire pros

Cons

"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current."

"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."

"Pricing could be better in comparison to other solutions."

"Storage. There could be better storage."

"I would like to see a Nagios monitoring plugin which watches the health and performance of the system. The only one available just checks volume capacity."

"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter."

"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."

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

More Everpure FlashArray cons

"Replication and de-duplication could be better."

"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."

"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 think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."

"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."

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

"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."

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

More Kaminario K2 [EOL] cons

"Though it is a stable solution, its users may face some security issues at times...The security provided by the solution is one area that can be improved."

"I would like to see integration with the cloud, number one. Being able to spin SolidFire in the cloud."

"There is room for improvement with a focus on creating a centralized storage system, functioning similar to AWS."

"I now know their best practices associated with allocating IOPS to your LUNs; I wish that was more apparent to me when actually configuring the system."

"The user interface needs to be improved. Much of the client feedback involves comments such as "Oh, it's hard to navigate through.""

"The level of monitoring could be better."

"When you set up the nodes, we have to serial into each one of these nodes to configure the IP ranges. It's still very easy, but it's time consuming."

"It would be good to provide administrative access at the root level to be able to do things with the system, if need be."

More SolidFire cons

Pricing and Cost Advice

"The pricing is very attractive and it delivers performance for the money."

"The price of Pure Storage FlashArray is expensive."

"We evaluated Oracle and Hitachi, but Pure Storage had the better pricing."

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

"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."

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

"The solution could be cheaper."

"The licensing is $100,000."

More Everpure FlashArray pricing and cost advice

"The licensing is all-inclusive."

"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."

"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."

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

"Based on what I heard from other people, its price was on the higher side."

"It might be considered expensive, but when evaluating performance, it represents good value online because you pay for what you get."

"The price of this solution is more expensive than others."

"We would probably use SolidFire more, except we're getting more bang for our buck with our purchases of ONTAP right now, and the deal we made with NetApp, so it's more of just a cost decision"

"On a scale where one is a high price and ten is a low price, I rate the solution between three and four. It is an expensive solution."
