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.

Infrastructure Architect & CEO at Tirzok Private Limited

Offers reliable performance and availability for large deployments

I would like to see improvements in Red Hat Ceph Storage not because I necessarily think it needs improvement, but because I generally prefer to do things manually rather than following the containerization part. Current deployments are based on containers, but I deploy manually with my scripts and controls. If there are no Kubernetes-like requirements, I often prefer to deploy a whole manual process. I don't ask for improvements in the deployment model because Red Hat has its own philosophy about making things, but it's my personal choice that I prefer things manually. Some features are available only in the containerization part, so if those are also available in manual deployment, that will help.

Quotes from Members

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

Pros

"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."

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

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

"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."

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

"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."

"It is very easy to use, and it is very fast."

"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."

More Pure Storage FlashBlade pros

"Allows us to share files across multiple environments."

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

"It makes our file system sharing a lot easier, even across different continents. We have had file systems shared across different continents with no performance degradation."

"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."

"We can have multiple systems within the same file system."

"The high performance of the solution is its most valuable aspect. If you compare it to other storage solutions, it's much better."

"It is a scalable solution."

"I would rate my overall experience with IBM Spectrum Scale as nine out of ten."

More IBM Spectrum Scale pros

"Red Hat Ceph Storage is a reliable solution, it works well."

"I like the distributed and self-healing nature of the product."

"Data redundancy is a key feature, since it can survive failures (disks/servers). We didn’t lose our data or have a service interruption during server/disk failures."

"What I found most valuable from Red Hat Ceph Storage is integration because if you are talking about a solution that consists purely of Red Hat products, this is where integration benefits come in. In particular, Red Hat Ceph Storage becomes a single solution for managing the entire environment in terms of the container or the infrastructure, or the worker nodes because it all comes from a single plug."

"I really like that Red Hat Ceph Storage can be used as a total solution without any storage area network components."

"Without any extra costs, I was able to provide a redundant environment."

"The ability to provide block storage and object storage from the same storage cluster is very valuable for us."

"We use the solution for cloud storage."

Cons

"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."

"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."

"I would like to see better integration."

"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."

"It's on the expensive side, as expected for a niche product."

"The solution is expensive."

"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."

"There could be improvements in public cloud integration."

More Pure Storage FlashBlade cons

"Maybe it needs integration with HA."

"This is probably the biggest challenge, getting everything upgraded, because it just takes time. We wish it was a faster solution to be able to do everything at once, but you have do each node individually. The more nodes, the longer it takes."

"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."

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

"It would be helpful if there was a graphical user interface that could walk you through the deployment process. The instructions surrounding setup aren't the best. They need to be more step-by-step."

"The solution's pricing could be better."

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

"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

"When it comes to the capabilities of Red Hat Ceph Storage such as object, block, and file storage, I am not fully satisfied."

"Rebalancing and recovery are a bit slow."

"Please create a failback solution for OpenStack replication and maybe QoS to allow guaranteed IOPS."

"The storage capacity of the solution can be improved."

"The product lacks RDMA support for inter-OSD communication."

"I have not identified any drawbacks, however, the response to public platform inquiries could be faster."

"What could be improved in Red Hat Ceph Storage is its user interface or GUI."

"An area for improvement would be that it's pretty difficult to manage synchronous replication over multiple regions."

Pricing and Cost Advice

"I feel that the price could always be lowered."

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

"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."

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

"Licensing fees are paid yearly."

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

"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."

More Pure Storage FlashBlade pricing and cost advice

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

"The solution is costly but reliable."

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

"We never used the paid support."

"I rate the product’s pricing an eight out of ten."

"The price of this product isn't high."

"There is no cost for software."

"If you can afford a product like Red Hat Ceph Storage then go for it. If you cannot, then you need to test Ceph and get your hands dirty."

"The other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."

"The price of Red Hat Ceph Storage is reasonable."

"The operational overhead is higher compared to Azure because we own the hardware."

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.
