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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"We currently have four Pure Storage FlashArray boxes, and all the storage boxes are on an Evergreen subscription model where we receive the latest hardware and features without any cost in a completely non-intrusive task."

"The solution helps to simplify storage."

"The most valuable feature is its data reduction."

"It simplifies storage."

"It simplifies the overall management. We don't have to worry about storage anymore."

"The product has not gone down in a year, so I would say that it is stable, and we haven't seen any high spikes in read/write latency."

"Pure Storage is an amazing solution."

"It's easy to use, and the maintenance upgrades to get free controllers work really well."

More Everpure FlashArray pros

"The process of reallocating data from fast disks (SSD or SAS) to slow disks (SATA) gives you better performance and better use of resources."

"I would recommend to buy Dell EMC 3020 to anyone researching these type of solutions."

"I find this version to be more budget-friendly compared to products from other vendors. This aspect greatly benefits my customers. It's highly advantageous due to its affordability. The operational aspect is also noteworthy. Additionally, its availability and performance are commendable. The speaker are also equally powerful."

"Technical support has been quite good; we are very satisfied with the level of support we receive."

"We like the integration, the nodes themselves, the way that everything is integrated together, and it seems like it's less hardware to keep up with while speed and performance seem to be good on the hardware side."

"The setup is straightforward."

"It is fast and performs well."

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

More Dell SC Series pros

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

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

"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."

"Latency is definitely the big key for us."

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

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

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

More Kaminario K2 [EOL] pros

Cons

"With the introduction of Albireo technology and 81x data de-duplication reduction, Pure Storage better start looking at more effective de-duplication techniques."

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

"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."

"The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors."

"The time-to-market could be better at times, but I think that's true for all vendors of hardware."

"The pricing needs to be improved as they offer very high budgeting prices. Searching is a big challenge in Pure Storage FlashArrays, especially when trying to restore a VM."

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

"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."

More Everpure FlashArray cons

"Licensing, especially on the storage line, could use some simplification. It's not terrible, but, for example, with the Isilon series, they've gone to completely a la carte. A la carte is very difficult to traverse, as to what you need. It would be more beneficial, at least from my point of view as a customer, if they did it more like car companies do, where there are package lines"

"The initial setup is somewhat complex and should be made simpler to do."

"Dell SC Series is no longer available, while Dell PowerStore, which supports NVMe over TCP, is different and not very affordable."

"Compellent comes in the form of a component that's not true of a unified storage platform."

"In some customer cases, customers experienced more performance or latency."

"It's definitely affordable. Of course, it would be better if they made it cheaper, even more affordable."

"This solution could be improved if overall performance was improved and operated with a higher speed and supported a higher volume of RAM."

"Some menus aren't so intuitive."

More Dell SC Series cons

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

"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."

"Replication and de-duplication could be better."

"The management graphical interface needs more improvement."

"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."

"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."

"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."

"There are some mid-market SMB customers that it may not fit the best for from a pricing perspective, but for the vast majority of our customers, once we aware of it and learned about the technology which it performed with, it fits a very useful metric."

Pricing and Cost Advice

"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."

"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."

"It's expensive, but you get what you pay for."

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

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

"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."

"Pure has been flexible with us on the pricing models."

"The price, in general, is around $100,000, however, I know it costs more."

More Everpure FlashArray pricing and cost advice

"Always keep in mind, this is not just a enclosure with disks is a complete SAN as a service. There is software, license, and storage in one single solution."

"Support typically depends on the array. It can range anywhere from $7,000 to a couple of hundred thousand dollars."

"We have reviewed many platforms over the years. It is probably the best solution for its value."

"It has a good price point and offers some value-added enterprise features."

"The pricing of Dell EMC Compellent is competitive."

"We have found it to be affordable. Comparing the cost with other hardware, it seems to be right in line with the compute and the storage that we get with it."

"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."

"The maintenance is usually pretty good. It's not like some of the others where they increase it in the fourth, fifth, or sixth years."

More Dell SC Series pricing and cost advice

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

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

"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 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."

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