Eric Black

Solutions Architect at Recovery Point Systems

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.

Senior Consultant at SJT SOLUTIONS GMBH

Provides efficient synchronous mirroring capability and dynamic data management functionality

The initial setup is relatively easy but requires a certified DataCore implementation engineer to deploy the solution in a production environment. The deployment following the qualified procedure, typically takes about a week, depending on the amount of storage and the specific environment. With my experience, I can set up the system within two to four hours; however, the qualification process, which includes detailed planning and testing, adds additional time. It involves gathering the customer's requirements, preparing comprehensive documentation for validation, and conducting tests in collaboration with the customer. This documentation includes a site planning checklist, a pre-installation checklist, and a functional test plan to ensure everything is in order before deployment. Overall, I rate the process an eight.

Jeff Manuszak

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

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

"We can capacity plan at a greater level than we used to."

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."

"I would rate Pure Storage FlashBlade a ten out of ten."

"The most valuable features are the Metro clustering, and disaster recovery."

More Pure Storage FlashBlade pros

"The DataCore system has been rock solid since we have been using it - from 2007 on."

"It is a very stable solution."

"During the maintenance periods, on any part of the storage or VMware migration, we have had no downtime."

"The features I have found most valuable are the active-active, or so-called grid technology, and the integration into our VMware-vCenter."

"The use of the RAM cache allows you to speed up the writing and reading of data while also allowing for a possible increase in performance by increasing the RAM on the servers."

"It's a software storage solution that can scale as we like. There is also has a parallel feature that enhances the performance of the storage solution. We can separate storage and computing, and we can scale these two parts of the platform to meet business needs efficiently."

"Good security with this solution."

"SANsymphony is flexible, with many potential options for implementation. SANsymphony's can be used with VMware, Hyper-V, or even with a hypervisor agnostic approach. It can also be used for strictly physical non-virtualized solutions."

More DataCore SANsymphony pros

"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."

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

"Quest QoreStor is very stable compared to our previous solution."

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

"Quest QoreStor definitely saved us money."

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

"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."

"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."

More Quest QoreStor pros

Cons

"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

"The solution is expensive."

"Pure Storage FlashBlade should improve on more cloud integration."

"I have not seen ROI."

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

More Pure Storage FlashBlade cons

"I would like to see reporting added, such as a monthly connectivity report."

"It would be ideal if they were providing archive licensing with the ability to create a second pool on existing storage nodes."

"Management could be improved. The management console sometimes reacts very slowly."

"The cloud reporting interface is quite poor compared to other vendors."

"I think the performance reporting can be improved by adding historical statistics into a database for the purpose of comparing."

"If you're dealing with big databases or transactional databases, it might not be the best-suited solution. The design of DataCore's solution isn't oriented towards this type of data."

"One area where the solution could improve is its software platform. Many customers have expressed dissatisfaction with the software running on Microsoft Windows."

"I would like for it to improve into a more ergonomic management console and a translation into the French language. It should have some process for a shutdown of a VM properly in case of a problem."

More DataCore SANsymphony cons

"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."

"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."

"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. 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."

"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."

"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."

More Quest QoreStor cons

Pricing and Cost Advice

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."

"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."

"Our customers have seen a reduction in TCO."

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

"I rate the tool's pricing a seven to eight out of ten."

"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."

"The price is a little high."

More Pure Storage FlashBlade pricing and cost advice

"The cost is at the same level as other storage solutions and it is easy to understand the licensing."

"DataCore SANsymphony's pricing is very high and should be much cheaper."

"Make sure you are made aware of the annual subscription cost when purchasing."

"It is relatively expensive, and the additional costs for hardware and storage can make it a significant investment for customers."

"Pricing has improved but it is still expensive."

"This product has a good ratio between quality and price. In many cases, it's less expensive to work with DataCore than other storage systems."

"The pricing and licensing are better with DataCore."

"We have licensing costs on a yearly basis. They charge per terabyte, so in terms of cost, it can be very costly. They have three different features, and you have to pay extra for those."

More DataCore SANsymphony pricing and cost advice

"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."
