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.

Deliver improved performance in data processing and foster extensive AI initiatives

I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system. It achieved the best results when integrated with IBM hardware. Even though it is complex, it provided significant performance advantages in large-scale data management. Its fault tolerance mechanisms and integration capabilities make it popular for extensive AI initiatives and data processing tasks for organizations like Daimler Benz and Bosch.

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 solution provides many controllers."

"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."

"We have seen a reduction in the total cost of ownership by around 20%."

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

"The onboarding and integrated monitoring tools are pretty good."

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

"The most valuable feature is Safe Mode."

"The main feature I have found to be product replication."

More Pure Storage FlashBlade pros

"GPFS monitoring is the best feature."

"The profile share is a valuable feature."

"Technical support has been very helpful. They provide us with pretty good solutions that we can implement moving forward."

"I rate this product ten out of ten."

"It has been pretty reliable throughout the years. As far as capacity is concerned, it can handle most heavy loads."

"We are using it for monitoring all of our storage."

"The most valuable feature is the ability to share files across different platforms."

"It is incredibly scalable and stable."

More IBM Spectrum Scale pros

"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."

"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."

"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."

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

"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."

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

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

"Quest QoreStor definitely saved us money."

More Quest QoreStor pros

Cons

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

"I would like to see more monitoring capability included in the next release of this solution."

"I would like to see the licensing fees improved as well as the price per terabytes."

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

"The speed could be improved."

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."

"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."

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

More Pure Storage FlashBlade cons

"The initial setup is complex, especially if trying to avoid erasure coding, as it requires more discs. Avoiding erasure coding can significantly increase costs."

"Maybe it needs integration with HA."

"Making it a little easier to add bad file sets would help. There is a transition to how you add storage and how you add a file set, so making that a little smoother would probably be my recommendation."

"The solution's pricing could be better."

"There can be improvements in fault tolerance and making erasure coding faster."

"Integration with other vendors is not available."

"I believe there is no graphic user interface, so they should include it."

"The main issue that we have now is with the encryption. They want to use more metrics in encryption, which is not working very well."

More IBM Spectrum Scale cons

"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 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."

"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."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."

"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 Quest QoreStor cons

Pricing and Cost Advice

"Licensing fees are paid yearly."

"The price could be cheaper."

"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."

"I understand that it is competitively priced compared to other brands."

"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."

"The pricing for FlashBlade is between cheap and moderate."

"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."

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

More Pure Storage FlashBlade pricing and cost advice

"The licensing is based on the number of terabytes."

"The solution is costly but reliable."

"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."

"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."

Overview

FlashBlade is the industry’s most advanced scale-out storage for unstructured data, powered by a modern, massively parallel architecture to consolidate complex data silos (like backup appliances and data lakes) and accelerate tomorrow’s discoveries and insights.

Pure Storage

IBM Spectrum Scale is a cluster file system that provides concurrent access to a single file system or set of file systems from multiple nodes. The nodes can be SAN attached, network attached, a mixture of SAN attached and network attached, or in a shared nothing cluster configuration. This enables access to this common set of data to support a scale-out solution or to provide a high availability platform. IBM Spectrum Scale has many features beyond common data access including data replication, policy based storage management, and multi-site operations. You can create a cluster of AIX nodes, Linux nodes, Windows server nodes, or a mix of all three. IBM Spectrum Scale can run on virtualized instances providing common data access in environments, leverage logical partitioning, or other hypervisors. Multiple IBM Spectrum Scale clusters can share data within a location or across wide area network (WAN) connections.
