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

"Pure Storage is extremely reliable — it's never failed."
"It does efficient work of storing data while still delivering the performance that you would normally expect from a higher priced solution."
"Even if it costs a little bit more, you do get more for what you pay."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"All my customers are pretty happy with most Pure Storage solutions."
"This solution has improved our organization. In the past, we had reports that were taking up to two hours and after switching to SSD storage the overall processing power dropped to half an hour. The end users saw an immediate performance gain."
"They have a very good support system, and the GUI is also very intuitive."
"The back-end data reporting for Pure Storage is phenomenal. The data that you can see on the performance of your customers' array, so you can be proactive about upgrades or enhancements, and is a phenomenal tool to have access to as a partner. I haven't seen this type of stuff out of anything of the other storage systems."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"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."
"Quest QoreStor definitely saved us money."
"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"The solution made our backups way more reliable."
"The most valuable feature of the StarWind Virtual Tape Library is the archiving to the AWS cloud."
"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."
"StarWind VTL allowed us to back up to virtual tape that was created within Veeam and upload the tape to the cloud."
"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."
"It is a stable solution."
"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."
"If you currently have Veeam there is no other solution that is as easy and affordable as StarWind."
 

Cons

"The only issue is the pricing. Because we have competition, our customers always take another brand and say they can save their investment."
"The 3PAR SSD arrays that we have are still failing a lot so even though we're under warranty, we still have to get someone out and usually have someone troubleshoot so that usually adds onto the cost. With Pure, we've had a disc fail and we pop it out and you pop it in and it's good to go."
"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"When it comes to Everpure FlashArray ports shown in the GUI, it would be better if, when one of the Pure array ports went down, there was a possibility to highlight that particular port which has gone down."
"The scalability of the solution is not as good as it probably could be."
"If they could make it cheaper, that would be something."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"The air gap feature is something I'd really like to see in QoreStor."
"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."
"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 initial installation can be complex and should be simplified."
"In practice, it is somewhat technical to deploy and manage, but overall it gets the job done."
"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."
"The main thing that I felt could be improved was having an estimated time of completion for the virtual tape uploads to the cloud."
"The solution's training process and online documentation could be more thorough."
 

Pricing and Cost Advice

"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"The license for Pure Storage FlashArray includes the support and there are no additional payments that are needed. This is not an inexpensive solution, you need to understand the value of your data before you use a backup solution."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"We lost a lot of customers because we couldn't compete on price with other vendors."
"The pricing of Pure Storage FlashArray is reasonable."
"Pure Storage FlashArray is expensive."
"The cost has room for improvement."
"The price is reasonable."
"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."
"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 initial setup and deployment are also covered in the purchase at no additional cost."
"The solution is cost-effective."
"If you currently have Veeam there is no other solution that is as easy and affordable as StarWind."
"The pricing of the solution could be more flexible to meet the needs of smaller to mid-market size companies."
