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

"Firstly, dedupe is the most valuable feature, hands down, and simplifying storage is also a big win overall."
"It worked flawlessly."
"Even if they weren't one of the fastest arrays in the entire industry, I would use them for their support model and ease of use."
"The deduplication and compression meet all of our system requirements."
"The seamless integration into the public cloud has improved my organization."
"The tool has reduced our power consumption."
"It is the SAN backbone for our company."
"I have seen a huge increase in speed and performance on our databases."
"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."
"Quest QoreStor is very stable compared to our previous solution."
"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."
"Quest QoreStor definitely saved us money."
"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."
"We need revisions and safe backup so that it could be held up in court, but deduplication and compression are the main features why we have Quest QoreStor. That's where it really shines. I use ZFS and XFS at home, and Quest QoreStor is even better."
"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."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"StarWind SANs come with outstanding support."
"You can turn your local disk storage into high-availability iSCSI storage."
"Once the solution has been deployed, we have had no issues, with everything always in sync, leading to an estimated ninety-nine percent reliability afterward."
"Ease of installation, configuration, and management."
"The top-notch support before, during, and after deployments are better than any other vendor I have come across."
"StarWind Virtual SAN offers high availability and data resilience features to prevent data loss if hardware fails."
"StarWind Virtual SAN software solves our problems."
"It has given the company an almost zero possibility of downtime."
 

Cons

"Everything has been good, but we faced one issue last year while migrating volumes from one Pure Storage to another. The snapshots were not visible in the Veeam backup portal."
"We would like to integrate it more with our backup solutions."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"The initial setup of the product is complex."
"The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors."
"In the next release I would like to see integration into other third-party player providers like Google."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"The ransomware protection of QoreStor could use improvement."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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."
"The setup of the software is definitely not the easiest thing in the world."
"The air gap feature is something I'd really like to see in QoreStor."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"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."
"There is a general lack of documentation, especially up-to-date documentation to get started."
"The system failovers properly on its own without too much worry."
"The GUI deserves a little love."
"There is no Italian-language version of the software available."
"It is hard to find adequate technical documentation on their support website."
"I found that certain browsers are not fully compatible with the administration web access portal."
"Perhaps more reporting features on the utilization, usage, and performance of the configured high-availability images and underlying physical disks would be helpful."
"New versions of this solution should be tested more thoroughly before the release as we had a few problems with one version due to a bug."
 

Pricing and Cost Advice

"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."
"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."
"The price is too high."
"We do not incur additional costs beyond the licensing fee."
"I would rate it a seven out of ten for pricing. It could be improved."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"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."
"The cost has room for improvement."
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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 free version is great to use for labs or test environments."
"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."
"The setup cost, pricing, and licensing are very straightforward. They are exactly what you expect."
"The Price/Performance ratio for this solution is outstanding!"
"If you are looking at a traditional SAN for a small cluster, give StarWind vSAN because you will save thousands without any compromise."
"The support contract is well worth it. The price for it was very reasonable and their team has been very engaged whenever we reach out."
"I think the bang for the buck is much better with StarWind Virtual SAN."
"The StarWind VSAN business model is very cost-effective."
