Sowjanya MV

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

"We transferred our old architecture from hyper storage to all-flash storage, which made our business faster and more connected to our customers."

"Their support is top-notch, and their NPS scores reflect this."

"It has a small footprint, as the current system is only four units per rack, it's got good speed for the price as it uses eMLC, an advanced type of SSD, and it's very scalable, and we're not paying for capacity as we get free controllers every three years."

"It worked flawlessly."

"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."

"I am satisfied with this solution, and we plan to keep using this solution."

"I like its speed. It has all the features that I need."

"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."

More Everpure FlashArray pros

"The dashboard is very intuitive, and there are a lot of counters to diagnose what happens during a short period (like when a backup is in progress)."

"The dashboard is very intuitive, and there are many counters to diagnose what happens during a short period (like when a backup is in progress)."

"SANSymphony allows us to separate the storage software from the hardware, so we can replace or add any backend in the cluster without downtime and control costs while performing all maintenance operations during the day without impacting production."

"Oracle OLTP benchmark to test how it improves the performance while using flash drive NVMe."

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

"For us, fault tolerance is the most important feature of DataCore."

"The platform's most valuable feature is its synchronous mirroring capability, which ensures bit-identical copies of data and offers excellent failover capacity."

More DataCore SANsymphony pros

"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."

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

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

"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)"

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

"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!"

Cons

"Enhanced documentation and beginner-friendly guidelines would benefit users with less configuration experience."

"There are a lot of things to improve."

"I think replication is one area that still needs improvement."

"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."

"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."

"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."

"I would recommend improvements in the graphical user interface, specifically a detailed hardware view that would allow us to see the individual drives and individual controllers more easily, as currently, they are presenting only a higher-level view."

"There is not a great need for improvement, but better pricing could be beneficial."

More Everpure FlashArray cons

"The so-called hyperconverged infrastructure edition, sometimes known as vSan, should be addressed."

"If you're dealing with big databases or transactional databases, it might not be the best-suited solution. The design of DataCore's solution isn't oriented towards this type of data."

"DataCore is currently working with Veeam software for a better integration; this is my only desired missing feature today."

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

"For customers or technicians who don't speak and understand English, it would be great to have other language support, all the more so given the number of countries in which SanSymphony is used."

"The cloud reporting interface is quite poor compared to other vendors."

"Right now, the version used is run on Microsoft Windows Server. Having a Linux version or even an appliance would be better as it would eliminate the use of additional licensing for another piece of hardware."

"One limitation of this solution is that it's Windows-based, e.g. one requirement to install DataCore SANsymphony SDS is putting it on a Windows server machine. It relies on Windows and that is a limitation because there are some customers who are looking for non Windows systems."

More DataCore SANsymphony cons

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

"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."

Pricing and Cost Advice

"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."

"I don't know the exact cost but it's around $1,000."

"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."

"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."

"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."

"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."

"I would rate it a seven out of ten for pricing. It could be improved."

"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."

More Everpure FlashArray pricing and cost advice

"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."

"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."

"Make sure you are made aware of the annual subscription cost when purchasing."

"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."

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

"The cost is at the same level as other storage solutions and it is easy to understand the licensing."

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

"The pricing and licensing are better with DataCore."
