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

"The most valuable features I have experienced are the centralized management and redundancy under speed of the right disk."

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

"Pure Storage FlashArray is simple and easy to use. It offers protection when removing devices. It has the ability to undo deletes."

"It has improved the way our organization functions by improving the resilience of our infrastructure by quite a bit."

"Performance is the most valuable feature."

"Technical support has been amazing."

"The performance levels and the storage have improved my organization because we're a 95% virtualized environment and we're able to allocate resources as needed and manage our whole infrastructure that way."

"Overall, the best returns on investment have been operational simplicity, reliability, and reduced management overhead."

More Everpure FlashArray pros

"The deduplication functionality is great. We have seen a lot of benefits in the deduplication ratio. So, it has proven that it is a good cost savings."

"3PAR is different from other storage solutions because it uses a chunklet when we initiate the storage. Every disk is submitted as a 1 GB chunklet. This chunklet can be RAID 1, 4, 5, or 6. This fabulous feature is very useful for me because I can distribute the RAID for any volume. The adaptive optimization is the biggest feature in 3PAR. 3PAR is very usable with thin volume because it detects zeros while writing. Every time I tell the hypervisor to make the full provisioning, it makes the volume as simple provisioning in 3PAR, not full provisioning. Other vendors take this volume as thick provisioning because of which the capacity is reached quickly. It doesn't happen in 3PAR because it detects zeros. It only writes the data, and it doesn't write zeros. There are two processors in 3PAR: the ASIC processor and the main processor. The ASIC processor detects zero writing and doesn't write it, which is a big feature in 3PAR."

"The 3PAR is very reliable, most of our performance complaints went away after we put the 3PARs in, and it is simple to manage and easily serviceable by our technicians."

"From a comparison of bang for the buck, what you get for the money, I'd have to say they are one of the market leaders."

"The solution has increased our performance."

"I have a lot of applications that need higher IOPS, and 3PAR achieves this operation normally without any issues for the management."

"The chunklet technology is the main benefit out of 3PAR. The way it subdivides. It is using more logic to subdivide the drives into smaller pieces."

"Multi-tier storage was the primary reason that we bought it. I also love the interface that you use for administering it."

More HPE 3PAR StoreServ pros

"From my perspective, it is a huge success fulfilling everything we needed and more!"

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

"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."

"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."

"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."

"Technical support is absolutely great."

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

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

More Kaminario K2 [EOL] pros

Cons

"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."

"The price of the Pure Storage Flash Array is too high and there needs to be more contract clarity."

"On the technical side, the way that the array performs cleanup and garbage collection sometimes pushes it close to 100 percent utilization, causing some stress."

"I would like to see them develop the ability to integrate with more AWS services."

"The number of Filesystems is limited, which it is not on the EMC VNX."

"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."

"The best way to improve Pure Storage FlashArray is the active DR because that can get very confusing, especially when you're trying to test a failover and replicate back; better instructions on how to do that would help because we actually lost an entire volume when we were testing out some stuff as the fingerprint got reinitialized, and when you replicated back, it didn't know about that volume, causing a failure in that process."

"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."

More Everpure FlashArray cons

"The solution must be vertically and horizontally expandable."

"It's a very complex platform to manage and it's not cheap either. It doesn't really give us the level of flexibility we had for very, very small workloads."

"Licensing is still a pain point."

"The interface could be improved to match the system."

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

"...sizing is everything. If you don't do the sizing right and you don't understand every detail of the product, how it works, you can be in a very unpleasant situation when you pay half a million dollars and you have a product that does not work as you expected."

"We are using All-Flash Storage, and there are some difficulties with it."

"It's not a very good solution. We found EMC and other storage solutions can help the client a bit more in terms of reaching their target, having the flexibility they need, and offering better backups and integration."

More HPE 3PAR StoreServ cons

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

"The management graphical interface needs more improvement."

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

"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."

"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."

"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."

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

More Kaminario K2 [EOL] cons

Pricing and Cost Advice

"The pricing of Pure Storage FlashArray is reasonable."

"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."

"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."

"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."

"There is always room for negotiation."

"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."

"There are no fees for licensing. The hardware is paid for only once."

"It's priced higher than the market."

More Everpure FlashArray pricing and cost advice

"They have added features, such as the compression and duplication, which have further increased our ROI."

"We purchased the solution as CapEx and we only pay support now. I find the pricing fantastic."

"The solution's price is reasonable."

"This licensing fees for this solution are merged with all of our HP annual costs, which in total are a couple hundred thousand dollars."

"The price of the solution could be reduced for the license and for support."

"It makes for less administrative overhead."

"The total cost of ownership really is worth every penny."

"This solution is expensive. We pay every year for support. It's a lump sum because we pay for data center support services, and everything is included in one."

More HPE 3PAR StoreServ pricing and cost advice

"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."

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

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

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

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

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