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.

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.

Flexible and reliable with helpful support
I am not sure if this is a limitation of my physical hardware or if it is the software itself. However, I would like the throughput to be faster. Who would not like things to be faster? It would be nice if StarWind could come up with a best practice document for configuration. I had to do some playing around in my environment with test runs to get the configuration that really allowed for the maximum amount of throughput that I was going to get with the software. Once I had figured out what worked best, the solution was rather fast for backing up 30+ TB of data

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It saved a lot of space, as far as physical space in our data center."
"From the first test that we have conducted, we are very satisfied with this solution."
"The management features are well organized and they have a very good dashboard."
"It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage."
"We also use VMware integrations developed by Pure, their plugins in our vCenter environment. They help by allowing our non-technical operations teams to deploy new data stores and resize data stores without me having to involve myself all the time to do those simple tasks."
"It is all-flash. This makes it a lot faster than the rest of what we have, as it is able to drive high I/O loads, which is big for us."
"Now they are trying to add more and more applications because they're getting better performance and stability."
"Now, with Pure Storage, we have totally eliminated that problem."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"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 is very stable compared to our previous solution."
"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."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"Quest QoreStor definitely saved us money."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"StarWind VTL allowed us to back up to virtual tape that was created within Veeam and upload the tape to the cloud."
"The most valuable feature of the StarWind Virtual Tape Library is the archiving to the AWS cloud."
"It is a stable solution."
"We simply replicate our backups from Veeam to the virtual tape library that StarWind implements, while magically transporting those to B2 for our offsite backup requirements."
"If you currently have Veeam there is no other solution that is as easy and affordable as StarWind."
"I like the fact that we can simultaneously upload the virtual tapes to different cloud providers, and the settings can be adjusted to speed up the upload times even further."
"The support that they provide is excellent, with 24 hours a day seven days a week support, and all the engineers and the support staff know the solution very well."
"The solution made our backups way more reliable."
 

Cons

"The only minor issues that come to mind are that, every once in a while, a hard drive will go bad. Also, the solution should be cheaper."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"Pure Storage FlashArray has not helped to decrease the total cost of ownership, and I believe our total cost has probably gone up, but that's balanced by our increased amount of data and number of use cases."
"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."
"I would prefer that they lower their pricing."
"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."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"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."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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 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."
"The solution's training process and online documentation could be more thorough."
"The initial installation can be complex and should be simplified."
"I am not sure if this is a limitation of my physical hardware or if it is the software itself. However, I would like the throughput to be faster."
"In practice, it is somewhat technical to deploy and manage, but overall it gets the job done."
"The main thing that I felt could be improved was having an estimated time of completion for the virtual tape uploads to the cloud."
 

Pricing and Cost Advice

"There are no licensing fees aside from the support."
"We have seen a reduction in total cost of ownership (TCO)."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"The cost has room for improvement."
"There are no licensing fees or other costs."
"We are finding the TCO of flash to be lower than SSD implementations."
"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 price, in general, is around $100,000, however, I know it costs more."
"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."
"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 solution is cost-effective."
"The pricing of the solution could be more flexible to meet the needs of smaller to mid-market size companies."
"The initial setup and deployment are also covered in the purchase at no additional cost."
"If you currently have Veeam there is no other solution that is as easy and affordable as StarWind."
