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

"I never have to worry about its performance or if it is the root cause of an issue."
"The solution offers amazing performance."
"Their technical support is excellent. It's the best out of any of the vendors we work with."
"The administration is very easy and quite minimal, the performance is very good, the installation is pretty straightforward, and technical support is good."
"After switching to Everpure FlashArray, we saw significant results, as whatever hardware we used before is now compressed to 80%, maximizing space utilization in a single system."
"After the implementation, the time to run the process was reduced to minutes and it did not require any manual intervention from our DBAs."
"This solution is very scalable."
"The benefits were realized right away. Between the flash array and the compression, you can really see how good it is. Our databases run a lot better now."
"Don't go with EMC. Go with IBM. Go with this product. Absolutely. It's a very good product compared to the competitors."
"My advice to those wanted to implement this solution would be it is very useful and will give you all the details you need; how to set up the data movers, make sure they are balanced so that the load is distributed evenly, how to set it up and get all the documents in place once you log in."
"I love the SVC."
"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's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."
"We are happy with the support that IBM provides us."
"I like that it can virtualize more than three hundred storage providers."
"The IBM Spectrum Virtualize has gone from strength to strength but at the same time setting the bar for what's possible in the storage virtualization market."
"StarWind SANs come with outstanding support."
"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."
"By having StarWind, we're able to minimize maintenance impact and coordinating different support to be available around those timeframes."
"It has been extremely stable for the three years we've been running it."
"StarWind has allowed us to virtualize our environment without the huge expense of a dedicated SAN, putting cluster technology and its benefits within our reach."
"This solution enables us to make better cost-effective use of our existing hardware and leverage the current infrastructure at a higher level than we could before."
"StarWind vSAN has translated to a huge improvement in speed and high availability compared to our old iSCSI shared storage solution."
"Besides being 80% cheaper than the other alternatives, the simplicity makes reconfiguration and support much easier."
 

Cons

"They could improve the price."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"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."
"I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"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."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware."
"Level 1 technical support needs improvement."
"Scalability needs some work in some areas. The number of volumes needs to be increased drastically."
"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."
"We are not happy with the technical support. In the last seven or eight years, I honestly think that IBM's technical support has gotten way worse."
"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."
"There are some caveats with scalability, such as volume count. We are highly limited by volume count at this point in time."
"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."
"Cheaper pricing and GUI should be developed in HTML5 as opposed to Java."
"I did not see any indication that StarWinds vSAN is a usable solution with non-GUI instances of Hyper-V."
"vSAN's free version does not have a graphical user interface."
"The cost seems a bit steep, and I wish it was less expensive."
"The only point they should improve is the amount of documentation available for the user, especially in the first preliminary phase in which we were testing the product on our own."
"A central management console may be nice to see all nodes."
"This is a great product."
"Currently, it requires you to jump in and out of virtual environments placing storage components on or offline, and all steps must be done in their proper order, or you can create an issue."
"I would definitely like to see quite a bit more on the monitoring side of things."
 

Pricing and Cost Advice

"It is cost-effective because after buying a subscription, they provide a service to upgrade hardware for free. They are providing so many features. When you consider the features provided, it is cost-effective."
"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."
"We have an Evergreen Storage subscription, which I think is a great feature."
"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."
"All storage is expensive so any price improvement would help."
"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."
"It is cheaper than NetApp."
"It has a lot of advanced functions for a reasonable price."
"We would like the CPU cycle to save more on the licensing costs for us."
"Do a proof of concept, if you are not comfortable jumping in, but do it."
"I think it is a good value for the price."
"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."
"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."
"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."
"The licensing is straightforward, with free and trial versions available."
"The pricing is more than reasonable."
"Once you buy the license, you are free to build your own hardware solution based on your needs."
"This solution has a great price for the functionality."
"The StarWind VSAN business model is very cost-effective."
"I think the cost of this solution is quite fair."
"We found that the pricing was perfect; simple and clear."
"The cost was ultimately low to implement, which allowed us to be 3-2-1 complaint."
