Sowjanya MV - PeerSpot reviewer
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

"It simplifies storage."
"It has improved my organization in the way that now we have lower latency, we get fewer complaints from customers, and we see a constant response time."
"Access speed and power consumption are most valuable."
"The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."
"We have seen savings in our storage, and the speed of deployment has gone from several days to a few minutes, reducing backup and restore times from 93 days to minutes and simplifying storage for us."
"Their support is top-notch, and their NPS scores reflect this."
"We currently have four Pure Storage FlashArray boxes, and all the storage boxes are on an Evergreen subscription model where we receive the latest hardware and features without any cost in a completely non-intrusive task."
"From the first test that we have conducted, we are very satisfied with this solution."
"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."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"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."
"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."
"Quest QoreStor is very stable compared to our previous solution."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"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 Windows-based StarWind GUI is easy to use and understand and integrates seamlessly with VMware's vSphere portal as well."
"It has allowed us to save a lot of time and money by letting us create a vSAN within a Windows VM on the environment it controls."
"The most valuable feature is the managed service, which has been an important part of monitoring our critical infrastructure."
"Being hardware agnostic is a must and definitely scored points for us."
"The best part is the easy way it operates with a very clear GUI without any unnecessary items."
"In summary, I think it's the best solution I could buy to achieve my goals."
"The instant failover, with vSAN copying data to the second node, allowed for the continuous availability of our applications."
"The ability to run a two-node cluster without a dedicated witness has made this an excellent product for small deployments, which is right on target for our needs in regional offices."
 

Cons

"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."
"There's always an opportunity for new feature functionality."
"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure. I can see the overall volume, but I would love to see things in a more granular level on the VM side."
"For scalability, I rate it a six out of ten. We reach a limit. We never reached this limit, however, the architecture allows you to go until a certain size, and after that, you have to buy another array."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"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."
"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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"The ransomware protection of QoreStor could use improvement."
"The setup of the software is definitely not the easiest thing. I worked a lot with Quest engineers, especially in the early days when we were first testing it and trying it out. I actually had some of the developers working with us at one point because they were going through these point releases, and I was having trouble getting it to work in this S3-compatible situation. We got it all working eventually, but setup is definitely not the easiest thing in the world."
"The setup of the software is definitely not the easiest thing in the world."
"Some of the documentation seems to be a bit older and refers to deprecated items."
"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."
"Ongoing improvements in read and write performance would help meet increasingly demanding workloads."
"I would like to see an extensive set of cmdlets that could allow for easier automation as well as status management."
"A mobile app to sync up for overview and status would really be helpful."
"vSAN's free version does not have a graphical user interface."
"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."
"In testing, we found some features in the Linux appliance were missing."
 

Pricing and Cost Advice

"We have seen a reduction in total cost of ownership (TCO)."
"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"For us, as the customer, it reduced the price of the management."
"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"FlashArray is expensive, but the quality justifies the price."
"The cost has room for improvement."
"The Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again."
"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."
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"The free version is great to use for labs or test environments."
"I think that purchasing StarWind Virtual SAN Professional Edition would be optimal for most."
"This is the best priced solution for an SMB."
"Licensing is based on nodes rather than TBs, which means that the users are free to increase storage capacity without putting thought into licensing."
"Licensing is easy and the whole package is cost-effective."
"StarWind is best price/performance for SMB."
"The license is reusable. We can always rebuild it and apply the license. Then, boom, we get new servers, apply the license, and we're back up and running."
"It's priced fairly. It was definitely cheaper than the competition. The licensing terms are straightforward and reasonable."
