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 platform has improved data performance and has provided reliable support for my clients

It's difficult to know how DataCore SANsymphony can be improved. I think DataCore SANsymphony could be deployed on Linux environments, which could be a great thing for clients. I would like to see the stabilization of the Veeam implementation in the future, and perhaps the integration or officialization of compatibility with Proxmox and XCP-ng. With Proxmox, it wasn't easy while integrating it with third-party solutions. It's working, but it was a bit difficult to deploy.

Technology Sales Director at a tech vendor with 51-200 employees

Our company needed IOPS to solve the bottleneck on the storage side, but storage upgrade costs were awful. We achieved IOPS values nearly 6-10 times faster without any hardware upgrades.

Incredible IOPS increase in storage: IOPS is required to fulfill a disk job faster. It is input/output per second. When you request a report on your SQL server, you need as much as IOPS you can. So many IT guys put their most important databases on SSD disks to reach the maximum IOPS within their storage. But SSD disks are still so expensive. On the other hand, if you have multiple VDI systems in different locations, you will experience boot storm every morning on your VM servers. You need IOPS to handle this problem and it leads you to buying more SSD. With FVP deployment, you create more IOPS than by adding SSD disks, with a lower rice. Additionally, you will be able to create tiering across your clusters. * Architect dashboard tool: You can see the overall performance of your FVP cluster. It even provides valuable info that VMware can't report to the user about the VM performance. You can add sources on your cluster or move VM systems among tiered clusters. Also, it is possible to see the amount of latency decrease and IOPS created without adding any SSDs to the storage. * Low initial cost * Works with different flash resources such as NV PCI cards, memory and SSD * Ease of use * Stability

Quotes from Members

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

Pros

"While all these products have their own uses, Pure Storage FlashArray is in a market of its own."

"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."

"The back-end data reporting for Pure Storage is phenomenal. The data that you can see on the performance of your customers' array, so you can be proactive about upgrades or enhancements, and is a phenomenal tool to have access to as a partner. I haven't seen this type of stuff out of anything of the other storage systems."

"The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."

"It's reduced our overhead management time on storage, since it is so simple to get in and just provision a volume, present it to the host, and then you are done."

"Their evergreen solution is probably the most needed in any industry, especially today in unprecedented times and supply chain issues, their evergreen solution is amazing."

"The speed is the most valuable feature of this solution."

"Performance, deduplication, compression, and fast response time for requests from servers and applications."

More Everpure FlashArray pros

"DataCore is very fast storage, applications start faster, and database access is improved."

"As DataCore SANsymphony SDS is good software, it doesn't need to improve much."

"The documentation repository is really useful and kept updated."

"DataCore SANsymphony's stability is okay."

"I am very happy with this product's ability to adapt, increase, and modify existing infrastructures."

"We are now able to run a hot standby solution for our virtual systems with separated server rooms (in case of fire), and so we can minimize downtimes of our IT infrastructure."

"It is true storage virtualization at its finest."

"DataCore gave us speed, redundancy, reliability, and works great with our backup system."

More DataCore SANsymphony pros

"I became an instant fan of FVP, it’s easy deployment and awesome performance gains…"

"By adding storage intelligence at the server tier, it enables an architecture decoupling storage performance from capacity to utilize high speed server media in conjunction with any shared storage to deliver the maximum virtualized application performance at the lowest cost."

"From your customers point of view they will notice a great deal of performance improvement and performance consistency while using their applications running on your VMs!"

"The analytic data that is reported using PernixData Architect is by far the best storage metrics we have been able to gather on our environment."

"Instead, we chose FVP and achieved IOPS values nearly 6-10 times faster without any hardware upgrade."

"Boost storage performances giving new life to our existing storage investment Possibility to use just RAM or both RAM and SSD storage PAYG model licensing (at least for CSP)"

"Well, FVP2.0 is major step for PernixData and it should be highly usable as addition on any type of storage now."

Cons

"I would rate this a seven out of ten because it's a good performance storage, but the price is a little bit high."

"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."

"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 box-to-box encryption on replication included in the next release."

"The 3PAR SSD arrays that we have are still failing a lot so even though we're under warranty, we still have to get someone out and usually have someone troubleshoot so that usually adds onto the cost. With Pure, we've had a disc fail and we pop it out and you pop it in and it's good to go."

"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."

"The difference in pricing could become a problem for Pure because the commoditization of the solutions could lead to a different price being a problem."

"The only minor issues that come to mind are that, every once in a while, a hard drive will go bad. Also, the solution should be cheaper."

More Everpure FlashArray cons

"The management should take place via OS-independent access; here a web-based client would be desirable."

"NVMeoF should be implemented. This protocol will play a major role in storage infrastructure in the future."

"SANsymphony is missing some features that vSAN has. For example, vSAN has a special feature called continuous data protection. It provides the ability to go back in time to a given moment. You can see what was on your disk in the past up to two weeks. That's a great feature because ransomware attacks are increasingly common, and that provides you some kind of protection."

"I think the performance reporting can be improved by adding historical statistics into a database for the purpose of comparison."

"If it could integrate to a cloud gateway, then we could carry it directly to storage, instead of having middleware in between the storage and the cloud."

"Deduplication works but implementing it is complex."

"Having an enterprise "Storage Dashboard" that can show capacity, usage, performance, and any issues would be very beneficial."

"The main problem is there is no DataCore OS."

More DataCore SANsymphony cons

"I would no longer recommend this product since the company has been bought by Nutanix and the brand is effectively being killed off."

"Right now, you can only use this technology in VMware environments."

"Technical Support: 7/10 - qualified, but it's a little bit rigid to find a workaround for our previous situation."

Pricing and Cost Advice

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

"The price is very reasonable when compared to other solutions."

"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."

"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."

"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."

"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."

"Price per terabyte is substantially higher than their competition. We would like to see it drop."

"We have seen a reduction in TCO."

More Everpure FlashArray pricing and cost advice

"Pricing has improved but it is still expensive."

"The pricing and licensing are better with DataCore."

"This product has a good ratio between quality and price. In many cases, it's less expensive to work with DataCore than other storage systems."

"DataCore SANsymphony's pricing is very high and should be much cheaper."

"This solution allows the use of off-the-shelf hardware and charges by the TB of storage."

"It is relatively expensive, and the additional costs for hardware and storage can make it a significant investment for customers."

"We have licensing costs on a yearly basis. They charge per terabyte, so in terms of cost, it can be very costly. They have three different features, and you have to pay extra for those."

"The solution is cost effective."
