High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

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.

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

"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."

"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 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 initial setup is pretty quick."

"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."

"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."

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

"The solution provides many controllers."

More Pure Storage FlashBlade pros

"GPFS monitoring is the best feature."

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

"It is incredibly scalable and stable."

"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."

"The profile share is a valuable feature."

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

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

"I rate this product ten out of ten."

More IBM Spectrum Scale pros

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

"The configuration of the solution and the user interface are both quite good."

"I can compare Red Hat Ceph Storage with products from other vendors; I explored quite a few, but I still find that Red Hat Ceph Storage is making the most disruption."

"Ceph Storage allows us to add value related to cost and offers a unique experience compared to traditional storage."

"Ceph has simplified my storage integration. I no longer need two or three storage systems, as Ceph can support all my storage needs. I no longer need OpenStack Swift for REST object storage access, I no longer need NFS or GlusterFS for filesystem sharing, and most importantly, I no longer need LVM or DRBD for my virtual machines in OpenStack."

"The community support is very good."

"The scalability feature is used by all users and is critical for our operations."

More Red Hat Ceph Storage pros

Cons

"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."

"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."

"The speed could be improved."

"They need better integration with public clouds along with a better hybrid solution."

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

"I would like to see more deduplication."

"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."

"I would also like to see better support for CIFS workloads."

More Pure Storage FlashBlade cons

"We do have some issues where Spectrum Scale does not work as expected. We have seen our Spectrum Scale servers go down unexpectedly, but because we have a cluster, it does not take out the entire organization."

"I wish there were some graphical user interface to access the GPFS file system creation and monitoring."

"The biggest problem is that it is not able to provide block storage."

"Integration with other vendors is not available."

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

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

"Maybe it needs integration with HA."

More IBM Spectrum Scale cons

"If you use for any other solution like other Kubernetes solutions, it's not very suitable."

"I would like to see better performance and stability when Ceph is in recovery."

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

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

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

"Ceph does not deal very well with, or takes a long time to recover from, certain kinds of network failures and individual storage node failures."

"Some documentation is very hard to find."

"It would be nice to have a notification feature whenever an important action is completed."

More Red Hat Ceph Storage cons

Pricing and Cost Advice

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

"The price is a little high."

"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."

"The product is very expensive."

"Our customers have seen a reduction in TCO."

"We used a reseller for the purchase."

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 licensing is based on the number of terabytes."

"The solution is costly but reliable."

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

"Most of time, you can get Ceph with the OpenStack solution in a subscription as a bundle."

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

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

"We never used the paid support."

"There is no cost for software."

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

"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."

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.

IBM

Red Hat Ceph Storage is an enterprise open source platform that provides unified software-defined storage on standard, economical servers and disks. With block, object, and file storage combined into one platform, Red Hat Ceph Storage efficiently and automatically manages all your data.
