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.

Works at a financial services firm with 11-50 employees
Backup storage has shrunk dramatically with deduplication but still needs stronger security options
The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.
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

"Compared to Unity, these arrays offer significant advantages, such as NVMe technology and higher IOPS."
"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."
"The stability is perfect, the reliability is 100%, and the latency is always lower than 1 millisecond."
"When users don't call wanting to kill me, that's ROI."
"Like I tell everybody else that I deal with, if you want to focus your time on doing more valuable things for your company, and you deal with storage on a day-to-day basis like I do, the best thing you can do is put Pure in your environment."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"Everpure FlashArray has positively impacted my organization, particularly in performance and reliability, as we've had good improvements, making our applications run faster and giving us more confidence that they will not crash."
"The most valuable feature is its speed."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"Quest QoreStor is very stable compared to our previous solution."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"This software solution can be installed on many different types of hardware, which makes it very flexible. We can run it on virtual machines or virtual servers, providing convenience for solutions of varying sizes, from small to large."
"The access to our data is quicker and cheaper than it used to be in a traditional storage system."
"I have never worked with a company who is as responsive and helpful with everything I run into."
"The fact that the solution is vendor-agnostic allows it to be used with any virtualization vendor while remaining a powerful abstraction over storage."
"StarWind SANs come with outstanding support."
"We have been able to use more on-prem hardware to reduce cost and also use old disks that we do not trust enough for ordinary RAID or usage."
"StarWind vSAN allows us to create a hyper-converged server cluster on a friendly budget without being locked into a specific hardware vendor."
"You can build cheap, reliable, replicated virtual machines clusters using simple servers with an all flash disk or SAS\SATA hybrid tiered by performance storage."
"The ease of reaching the support team and their promptness for support is great."
 

Cons

"They could improve the price."
"In terms of the future, I have been excited by some of the copy data management stuff that they're talking about building into the environment. There are feature sets where I've done a lot of automation work. So, I am always looking forward to extensions of their API. They're also talking about a phone home centralized analytics database being used as a centralized management console with a list of new cloud features, but this doesn't seem finalized."
"Regarding documentation, it would be helpful if we could have access to the root passwords for administrative tasks."
"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"Automation could be simplified."
"We had one instance with an eight-hour outage in our primary data center because the upgrade to the controller failed, and the controller redundancy didn't work."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"They need to find another way of doing data protection, RAID is not working very well."
"The setup of the software is definitely not the easiest thing in the world."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."
"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field."
"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable. You have to have a connection to support to install."
"The importance of support is significant to me. I was working for a service provider, and all of our customers had a Quest or warning. Sometimes the support really underperforms."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"If it's possible to make a driver/solution that does not make use of the iSCSI targets of Windows, that would be great. I don't know if that's possible, however, it could make the configuration a little easier."
"Also, the pricing can be a bit complex depending on the features you need."
"StarWind relies on the underlying OS to manage the "SAN files" whether that would be a RAID volume, software RAID (such as LVM), etc. It would be useful if StarWind could incorporate the actual physical drive management inside of the solution, similar to Storage Spaces Direct."
"StarWind Virtual SAN could benefit from better integration with other tools and technologies, such as backup and disaster recovery solutions."
"It is hard to find adequate technical documentation on their support website."
"One point for improvement is to increase the performance capabilities of the Windows-based executable as compared to its Linux Controller Virtual Machine (CVM) equivalent."
"Some of the new hyper-converged tools seem basic as a single pane of glass dashboard."
"For me, the product could be improved by it being made cheaper."
 

Pricing and Cost Advice

"The licensing is $100,000."
"The cost has room for improvement."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"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."
"Pricing is very competitive, and it's better than other competitors."
"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."
"The solution is expensive."
"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."
"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"If you are looking at a traditional SAN for a small cluster, give StarWind vSAN because you will save thousands without any compromise."
"Licensing is based on nodes rather than TBs, which means that the users are free to increase storage capacity without putting thought into licensing."
"This is a good, economical solution compared to data storage systems."
"I think that purchasing StarWind Virtual SAN Professional Edition would be optimal for most."
"The cost seems a bit steep, and I wish it was less expensive."
"The scalability limitation for us is its licensing. At some point in the fairly near future, we will probably have to upgrade our license so we can store eight terabytes instead of four. We are currently at four terabytes, but we're starting to knock on the door of that capacity."
"The Price/Performance ratio for this solution is outstanding!"
"I would suggest that you download the free version, deploy in your lab, and play with it."
