The ability to leverage multi-tenancy along with immutability is a huge benefit for us

The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.

CTO at EDSI

Cost-efficient, highly scalable, and installable on different types of hardware

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. We are pretty lenient as we do a lot of IT support ourselves. We are not very hard on support organizations, but when a customer has a support issue, it would be easier if the support processes were a little bit more automated. It would be beneficial to have an easier way to upload diagnostic dump files. They can make it easy for the customer to collect the diagnostic data. 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. This is especially critical because it stores customers' backups, and a failure can have significant business impacts. If a customer does not have the backups and has a disaster, they can be out of business, so monitoring is key.

Quotes from Members

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

Pros

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."

"The initial setup is pretty quick."

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

"The most valuable feature of this solution is performance."

"The most valuable feature is Safe Mode."

"It's very easy-to-use."

More Pure Storage FlashBlade pros

"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."

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

"Quest QoreStor definitely saved us money."

"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."

"I would rate QoreStor a ten out of ten for what it offers for the price."

"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."

More QoreStor pros

"The best part of the solution is that you can actually scale up to a large number of operating systems without additional hardware."

"This is an easy-to-use product for adding flexibility to your storage solution."

"The single management panel is the main feature that is wonderful for the customer."

"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."

"VMware Software Defined Storage gives higher availability against data corruption."

"The solution is simple to configure and provides good performance and less footprint."

"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."

"The most valuable features of the solution are that it is easy to deploy and the support is really good."

Cons

"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

"The documentational aspect of FlashBlade needs improvement."

"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."

"The features provided for SMB customers are limited."

"Its configuration should be easier."

More Pure Storage FlashBlade cons

"The ransomware protection of QoreStor could use improvement."

"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."

"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."

"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 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."

"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."

More QoreStor cons

"VMware Software Defined Storage should include a shared database on a standard version."

"The performance is not as good as some competing products and reporting can be improved."

"It doesn't have the ability to be deployed on any kind of hardware and network connectors."

"There is room for more integrations and plugins into more storages."

"Simplifying the licensing model and making it cheaper would improve the solution."

"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."

"The license model of the product is an area of concern where improvements are required."

"I'd like to see improved hardware compatibility"

Pricing and Cost Advice

"The price of this solution could be made more affordable."

"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."

"Licensing fees are paid yearly."

"The price could be cheaper."

"We used a reseller for the purchase."

"The product is very expensive."

"Our licensing is renewed annually."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

More Pure Storage FlashBlade pricing and cost advice

"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."

"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."

"I believe there is a yearly licensing fee of around $2000 - $5000. I don't think there are additional costs above that but it depends on the type of infrastructure you're booting."

"The solution is very expensive."

"VMware Software Defined Storage is a slightly expensive solution."

"A single socket costs you around US $6,000 for three years. At a minimum, you have a three load cluster for a medium or enterprise-scale company. It can get quite expensive because you're likely to need four to six sockets on the other side. It comes to around $30,000."

"The product is quite expensive and is among the most expensive for this type of solution."
