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.

Unified storage solution supports cross-vendor replication and diverse industries
One of the most valuable features of IBM Spectrum Virtualize is its virtualization capability. It allows for the creation of stretched clusters, which are crucial for running Linux-based workloads that need mirroring for boot disks. The solution also provides asynchronous and synchronous replication, supporting operations across different data centers. Its deployment options across public, private, and hybrid clouds add to its versatility.
Jccerong Heron - PeerSpot reviewer
System Engineer at a tech vendor with 10,001+ employees
Support team has guided us through deploying virtual storage on legacy hardware and reducing operational costs
The reason I chose StarWind Virtual SAN for this particular scenario is really the features, the ease of use, and most importantly, the price. In my opinion, the best features StarWind Virtual SAN offers are easy integration with the system installed in the data center. The integration with my existing systems in the data center works well, especially with VMware, as we already have a big cluster in VMware, and the easy integration with that is helpful to solve some problems with the platform. StarWind Virtual SAN has positively impacted my organization by reducing OPEX costs. My OPEX costs have gone down as we reutilize some old servers, and this reduces the CAPEX of hardware in the data center.

Quotes from Members

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

Pros

"With this program, all of our applications are able to perform faster and this enables us to provide faster platforms and services to our customers and employees."
"Performance, deduplication, compression, and fast response time for requests from servers and applications."
"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"Using this solution has improved our consolidation ratio and it saves us a lot of space."
"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."
"Its ease of use is a very big thing for our customers; it's easy to set up and easy to maintain, and the support is automated, which is very good."
"Their support is top-notch, and their NPS scores reflect this."
"Pure Storage FlashArray provides immediate benefits to our customers with its easy setup process, allowing for instant use and rapid realization of advantages."
"It improves a lot of functions for our clients, the high availability is the best thing, I have been working with it for 15 years, and it's one of the most stable products that IBM has."
"It is very good for compatibility and stability."
"So when I say our storage services to our client were provided continuously - non-stop - for 12 months, it means that all customer servers had 100% uninterrupted, online SAN access to their data 24x7x365 (minus the power down)."
"I would recommend IBM Spectrum Virtualize because it is very robust, stable, and affordable, has very good performance, and is relatively easy to implement and use."
"It is a single pane of glass management interface, so once the storage is allocated to SVC, they only have one place to go to manage it for everything."
"I think probably one of the biggest benefits of this solution is that it is relatively easy to use and easy to understand."
"The most valuable feature for sure is the abstraction of the storage."
"It has the ability to seamlessly move hardware in and out as we refresh technology."
"The product's core feature of virtualizing our storage is by far the most valuable."
"The control panel is nice. It gives you a lot of good feedback as to the status and health of the VSAN."
"StarWind allows us to move virtual machines from one physical host to another, which greatly reduces the downtime required for maintenance."
"StarWind was a great price to performance ratio and it had a great support team behind it that helped me configure the solution and also size it to the customer's needs for them not to overpay for it and not get something that was not useful for them."
"As the client had acquired another company some distance away, they were concerned about having a single SAN in one location or the other. StarWind vSAN allowed us to keep a copy of the data local to each site without asking the client to pay for two SANs in addition to the two new servers they needed."
"In summary, I think it's the best solution I could buy to achieve my goals."
"Overall, we have saved many thousands of dollars by going this way."
"It helped us to save money by not having to purchase a new hardware SAN, the VSAN works better than our existing, older SAN, this software works well for the vital signs capture software we were implementing in a new Hyper-V failover cluster, our organization has less hardware to maintain since we didn't have to purchase a new SAN, and being able to run this software in the new virtual machines saved time and money."
 

Cons

"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"Pure Storage will have issues with positioning in the near future since its a relatively new company. For now, customers need a PoC to trust using the solution, as it can't stand on its brand name alone. They need to improve Pure Storage's marketing."
"We have not seen a reduction in our TCO nor have we seen ROI."
"It would be nice if Pure had something in its portfolio that provided higher deduplication and compression for backups."
"I would prefer that they lower their pricing."
"The negative aspect of Everpure FlashArray is that migrations can be somewhat complicated."
"A noticeable area for improvement is the support for object storage. The FlashArray does not natively support object storage like S3 or Swift, which pushes customers needing these features towards the more expensive FlashBlade."
"Technical support needs improvement. With respect to them being able to respond, they're more marketing people, less technical."
"Maybe sometimes we don't get responses back as fast as we would like, but they have always been very professional and they follow through."
"Adding features for data deduplication is one area of improvement."
"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."
"The feature that's kind of missing is getting us up to the point where we can help the application owners see where their data is at, understand it, and potentially help us breakout."
"I already discussed possible improvements with some of the guys from Hearnsley. One of our frustrations is when you go to expand volumes in a global mirror environment, you have to stop everything in order to expand. So that's one of the things."
"The training program could be improved."
"One very important feature is the analysis of the logs which should be there in the system."
"t is limited in terms of a single system to eight nodes or four, what they call IO groups."
"I had to buy upgraded support, which was not a problem, but it wasn't a prorated amount, so I paid for the support, the full upgrade, but I only got a couple of months out of it because it was only good until renewal time."
"We have, in rare cases, received conflicting guidance between different support folks within StarWind."
"When StarWind Virtual SAN for vSphere nodes go offline unexpectedly, the nodes have to re-sync disks fully which takes a long time. We had a power failure and when both nodes came online, VMware vSphere didn't see StarWind disks before I manually re-scanned them form ESXi administration console even though it should happen automatically"
"The documentation is good. However, if compared with competitors, it could be enhanced and made more professional."
"While it is possible to implement disk encryption in StarWind using Windows Bitlocker, such a solution can be a little tricky to manage, for example, when servers are rebooted."
"It would be nice to see a new UI for the windows client, as it is not the easiest to find settings."
"In the next release, they could make some graphs of the real-time loading, speed of storage, and interfaces. Of course, these can be viewed in other places. But, in the event of a malfunction or troubleshooting, this would be convenient."
"The interface of the management console of the StarWind Virtual SAN is complex, and it's difficult for the novice user to interact with the management having less knowledge or training in the product."
 

Pricing and Cost Advice

"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"The price is too high."
"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."
"We have an Evergreen Storage subscription, which I think is a great feature."
"The price is very reasonable when compared to other solutions."
"Its price is almost double than any other flash storage solution."
"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."
"Generally the bundled licensing is more cost effective and gives flexibility to the solution. Linking into the Spectrum Suite can also be advantageous, but depends on the scale of the enterprise."
"This solution came as an additional cost for the TSM package we chose."
"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them."
"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."
"It has a lot of advanced functions for a reasonable price."
"I think it is a good value for the price."
"Do a proof of concept, if you are not comfortable jumping in, but do it."
"We would like the CPU cycle to save more on the licensing costs for us."
"The premium support from StarWinds is a must have. The ability to have access to a storage engineer 24/7 is a must for a production environment."
"The cost seems a bit steep, and I wish it was less expensive."
"This solution is very accessible and the pro-level for support is well worth the cost."
"Licensing is based on nodes rather than TBs, which means that the users are free to increase storage capacity without putting thought into licensing."
"The setup cost is very low. The pricing is great."
"This solution has a great price for the functionality."
"The licensing is a bit weird. If you license the standard version of StarWind, it allows you four terabytes. Then, they have a pro version, but with the pro version, the only difference is it doubles the terabytes to eight."
"We evaluated other options and this one was the most cost-effective."
