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.

Managing data protection has become consistent and analytics now drive reliable performance

The most valuable features I find in Dell Unity XT include its robust performance and reliability. My thoughts about its in-line deduplication feature are positive. I would assess the value of Dell Unity XT multi-cloud support for my IT environment as highly beneficial. I do utilize Dell Unity XT data protection features. These features have assisted in ensuring data integrity by providing reliable backup and recovery options. Dell Unity XT integration with VMware helps scalability and availability through seamless operations and enhanced performance. My opinion on its Cloud IQ analytics is that it delivers insightful data that aids in operational efficiency.

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 have seen a good reduction in the amount of total storage space that we're using because of the deduplication."

"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."

"We experience fast demos and zero downtime; we do not experience any downtime with Pure Storage, thanks to resilience with Safe Mode, integration with backup software, and everything related to cyber resilience."

"The ease of management is one of the most valuable features of this solution. I would have also said that it's pretty fast but now our SQL servers are starting to beat it up pretty bad."

"The solution helps to simplify storage."

"The intuitive way of managing storage is what I appreciate about Pure Storage FlashArray, along with the clever use of flash modules, and absolutely the data reduction, because they are using that in a very clever way to do compression and deduplication."

"Even if it costs a little bit more, you do get more for what you pay."

"The experience has been very good so far for the company."

More Everpure FlashArray pros

"We use replication for disaster recovery (DR), making our DR process much easier."

"The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler."

"The most valuable features include snapshots, Thin Clones, and deduplication and compression."

"Delivers High IOPS, but more important, low latency as this is the most important part for our usage."

"We hear from our customers that it is stable."

"The NAS is also extremely easy to set up."

"It is scalable. Customers are going more into distributed architecture, so the Unity definitely has a scalable architecture built into that."

"The operating environment is very stable."

More Dell Unity XT pros

"Go with it. I tell people all the time they need to take a serious look at it."

"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."

"It is consistently stable; haven't had a single issue with it."

"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."

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

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

More Kaminario K2 [EOL] pros

Cons

"The initial setup of the product is complex."

"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."

"CIFS and SMB Shares cannot be mounted directly."

"The only thing I think could be improved is price. The price is the main concern for our customers."

"The price of the solution can improve."

"The latest release contains bugs that shouldn't be in a production environment. Two incidents impacted our client, including hardware-related bugs. They need to be more cautious in testing before they release."

"I like what they're doing, but some of my customers complain that they do not have all the bells and whistles and knobs to fine-tune workloads that some of the competitors have. In my opinion, that's good. All customers don't have dedicated storage gurus, and they can get themselves into trouble if they fine-tune too many of those high-performance knobs, but they do get knocked down. Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE. I personally think 95% of my customers are better off letting the system fine-tune itself. That was something that you needed to do 12 or 15 years ago, but now with all-flash, the technology can handle what it needs to handle. Customers just end up shooting themselves in the foot if they are tweaking too many default settings."

"It would be beneficial to have a separate pricing point for environments with lower performance requirements or less workload."

More Everpure FlashArray cons

"I don't know where the hybrid cloud might be going or what connectivity there is between what was recently released as far as AWS and being able to manage both of them. Maybe there is an on-prem and an AWS instance in the same window, like a single pane, but I would like to see something along those lines, where there wouldn't be two locations to manage storage."

"Inline dedup compression security is coming up as an issue, encryption, etc. is key for our customers. If we could have more ways to do software-based encryption, those are the features customers are asking us for, as well as replication."

"Dell EMC Unity is not sexy. It doesn't have all the flash and pizzazz of some of the other storage vendors."

"I don't feel the product is the leader in the market anymore."

"I'm not sure if it has a single pane of glass management console. That would be something we would like to see."

"We have had a lot of issues. We've got massive issues at the moment with IBM AIX, it's not stable, we have a lot of disk errors, production crashes sometimes, and that's not good for a retailer."

"There's always room for improvement with the UI. That can be a little cumbersome at times."

"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."

More Dell Unity XT cons

"Replication and de-duplication could be better."

"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."

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

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

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

"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."

"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."

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."

"Pure Storage FlashArray's pricing is very competitive."

"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."

"We lost a lot of customers because we couldn't compete on price with other vendors."

"We have seen a reduction in TCO."

"I have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it."

"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."

"While it comes with a higher price tag, this investment often translates to significant improvements in performance."

More Everpure FlashArray pricing and cost advice

"It was easy to order. We are a big Dell shop, so it was easy to purchase and get it in place, then up and running."

"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."

"The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes."

"From a pricing perspective, this solution is comparable to others on the market."

"I liked the price point when we purchased it."

"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."

"The solution should be cheaper."

"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."

More Dell Unity XT pricing and cost advice

"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."

"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."

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

"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."
