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.

Has high-speed data access and processing capabilities, distinguishing it as a leader in its storage solutions category
VIOLIN QV2020 lacks scalability. This affects both the timeframe for installation and the performance of end-users. Additionally, there's a challenge in deploying horizontally, either by deploying between different nodes or adding new ones. We have many customers. 50,000 users are using this solution. It depends on the projects being taken out of the operations team.

Quotes from Members

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

Pros

"Most of the problems that we had in the past with the performance in IOPS have disappeared. It has been a great improvement for our customers' services."
"Our storage phones home. It is smart and intelligent in that aspect, which has been huge for us. We don't have to be storage administrators."
"Everpure FlashArray is superior to any other solution I have seen, as the capabilities of the system outshine other vendors, and the stability and speed are unmatched by other vendors."
"It does everything they say it will do: It's very cost-effective compared to other big players, integrates very well with VMware, is tiny so we're saving power and space in the data center, and it's really easy for us to manage."
"If you're interested in using this solution, I recommend that you do the same — see if you like it."
"Now with Pure Storage, our developers work a lot faster and more efficiently which has definitely improved our productivity."
"The amount of data that I have moved to it from legacy storage has enabled us to retire units that are three or four times the physical size."
"I would highly recommend this solution; it has all the features we need and tests all the software solutions that are currently available and that will be available in the future."
"Being all-flash makes everything super-fast. It's also great to manage. That's the easiest part. We also have another SAN, from Pure, and the Unity is easier to manage than the Pure."
"It is simple to use and easy to manage. We don't touch it after we set it up."
"The most valuable feature is the integration with vCenter."
"This is a great storage solution and a product that I recommend."
"It's easy to use, easy to manage, easy to troubleshoot, and the process support is good."
"The architecture is robust; it was the good, old-fashioned storage array, block array for customers, and it's reliable."
"We can sleep at night because the support is great."
"The most valuable feature of Dell Unity XT is its support of protocols for both block, and file levels. It has the features a store solution should have."
"It has lowered batch times from 14 hours to two hours."
"VIOLIN QV2020 is the latest in terms of performance. It has high-speed data access and processing capabilities, distinguishing it as a leader in its storage solutions category."
"It’s simple to use hardware to fix performance issues. Our issue is poor coding/queries. This greatly speeded things up. It’s too costly to track down poor programming in applications. The price of a developer’s time to scan through all the coding is high compared to buying Violin."
 

Cons

"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"I would not say anything because we still do not use Everpure FlashArray fully."
"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."
"Reports of performance and LUN utilization could be improved."
"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."
"The only thing I think could be improved is price. The price is the main concern for our customers."
"I think the pricing for Pure Storage FlashArray is the major issue because all the great things come with the price, and a lot of customers simply are not willing to accept it."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"I would like to see a more seamless virtual box integration with the physical box which can replicate, because the setup of the replication is very difficult right now."
"Support and licensing are big things, in the end, that needs improvement."
"Technical support has gotten worse since the merger, for example, response time to SR creation."
"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."
"It could go faster. Make it bigger, better, and faster at a lower price, and I am there."
"We have had some downtime. Nothing is perfect. Unity’s have had some code-release problems, versions that, from a compatibility perspective, had some glitches which caused an outage. But, given the amount of Unity’s we run, that has been fairly minor and it hasn't happened at scale or across all of our Unity’s."
"Dell EMC Unity XT should present a path or a roadmap on how they could put their products on the cloud. This would have some value for their current customers."
"There's always room for improvement with the UI. That can be a little cumbersome at times."
"VIMM replacement is poorly designed."
"VIMM replacement is poorly designed. You have to slide out an entire drawer, remove the cover and then pop out the failed VIMM. I would like to see a front replacement just like with hard disks. This leaves room for error; for example, when you slide it out from the rack, you are moving cables along the cable management arm. This leaves the possibility of accidentally unplugging a cable from the array if it is not seated properly. Also, you might pinch the cables when sliding it back into the server rack."
"I set up Wi-Fi for storage, and since then, we haven't experienced any interruptions in service."
 

Pricing and Cost Advice

"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"It is cheaper than NetApp."
"It's a good price point and it's a solid product for the price."
"Pure Storage FlashArray's pricing is very competitive."
"There is an annual or perpetual license required for this solution."
"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."
"We feel that the pricing is fair and the licensing process was easy for both."
"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 the solution should be less expensive. However, at some point, you need to pay for facility and performance."
"Obtaining a warranty is easy."
"This solution is a good price for what you get."
"The pricing of Dell Unity XT is good."
"It is an average priced solution."
"Pricing for this product is manageable, though slightly higher than comparable products."
"Our CAPEX was close to $42,000 and operating costs are below $1000."
"The solution is very expensive."
"They will beat anyone’s price right now. They are struggling and just need to get product out their doors."
