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

"Pure Storage FlashArray has helped us decrease the storage footprint in a significant way; the dedupe and compression that they have is really good, and we're getting about four to ten in the deduplication and compression."
"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."
"We have integrated the solution with VMware, and the process was seamless."
"They are quite responsive and our local team was pretty good."
"I would recommend Pure Storage, as it is well-established."
"Pure Storage is an amazing solution."
"Running SAP on Pure Storage helps a lot without doing any further tuning to improve application performance. Our internal clients are happy."
"The most important feature of any storage array is its reliability, measured by its uptime."
"Quest QoreStor is very stable compared to our previous solution."
"The dedupe and compression are pretty extreme. On disk, we're getting dedupe rates of up to 65 percent of data and compression of 34 percent. When you go to the cloud, it's more like 76 percent for dedupe and almost 50 percent for compression."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"Quest QoreStor definitely saved us money."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"Deduplication is the most valuable feature. It saves us a lot of space. When we back up 100 terabytes of data, after dedupe, it only uses maybe five to six terabytes for the disk space in QoreStor."
"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."
"The features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."
"The Virtual SAN product has greatly improved the organization's infrastructure by allowing us to create a scalable, highly-available, and cost-effective storage system."
"Compared to similar solutions from NetApp etc., our savings were likely in the tens of thousands of dollars over the years, and we did not need to pay for features that we do not need."
"Starwind made it easy to deploy fully redundant, highly available storage at a low cost."
"Before VSAN, hypervisor configuration changes and updates resulted in VM outages. Now, downtime is dramatically reduced."
"It provides shared storage to multiple hypervisor hosts. Times had changed, however. StarWind Virtual SAN is the “software replaces hardware” for SAN. We have access control and CCTV systems up and running using Microsoft clustering and shared storage"
"The product allows extreme flexibility for SAN and hyperconverged infrastructure."
"The StarWind Virtual SAN management console is intuitive and easy to use."
"StarWind Virtual SAN is a very mature software that supersedes its capabilities with my use cases."
 

Cons

"There was some complexity in the initial setup."
"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."
"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."
"I think replication is one area that still needs improvement."
"It was not proactive communication."
"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."
"I want to improve the overall service level of the solution."
"I would prefer that they lower their pricing."
"The ransomware protection of QoreStor could use improvement."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"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."
"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."
"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something. So that when we don't do a backup, we want the QoreStor to stay offline. It would be a nice feature to have."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"The air gap feature is something I'd really like to see in QoreStor."
"High availability for direct attached hardware drives (without virtual disk layer) could be useful to increase the performance of StarWind virtual storage cluster."
"We would like the documentation to be more complete. Most items are covered, but if you don't know something, you may need to contact their support."
"The initial setup got a little confusing at a few points with differences between the VMware version in documentation vs the latest, etc."
"While StarWind.com excels in numerous areas, there are a couple of notable functionalities that it currently lacks."
"Areas for improvement in StarWind Virtual SAN include simplifying the setup process, especially for users with limited vSphere expertise."
"There is one issue as far as licensing goes and that is a lack of documentation online for users when transitioning from the free version to the paid version, or vice versa."
"I think the setup could be streamlined a bit."
"The console is something that I feel could be improved."
 

Pricing and Cost Advice

"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"The price-to-performance is good. I looked at Pure about three to four years back, but the price-to-performance wasn't right for us. Now, it's right."
"FlashArray is expensive, but the quality justifies the price."
"The price of the solution can be a bit expensive. There is an additional fee for support."
"The solution could be cheaper."
"Pure has been flexible with us on the pricing models."
"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."
"It's priced higher than the market."
"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 cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"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 was ultimately low to implement, which allowed us to be 3-2-1 complaint."
"I think the cost of this solution is quite fair."
"The setup cost is very low. The pricing is great."
"I would suggest that you download the free version, deploy in your lab, and play with it."
"This solution is very accessible and the pro-level for support is well worth the cost."
"Cost is affordable and licensing is smooth."
"For two nodes, it cost us $10,000, and we spend $2,000 a year on support."
"This solution has a great price for the functionality."
