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.

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.

"It is incredibly scalable and stable."

"It is a scalable solution."

"Allows us to share files across multiple environments."

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

"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."

More IBM Spectrum Scale pros

"Replicated and erasure coded pools have allowed for multiple copies to be kept, easy scale-out of additional nodes, and easy replacement of failed hard drives. The solution continues working even when there are errors."

"Most of the features are beneficial and one does not stand out above the rest."

"It has helped to save money and scale the storage without limits."

"radosgw and librados provide a simple integration with clone, snapshots, and other functions that aid in data integrity."

"High reliability with commodity hardware."

"We have some legacy servers that can be associated with this structure. With Ceph, we can rearrange these machines and reuse our investment."

More Red Hat Ceph Storage pros

Cons

"The features provided for SMB customers are limited."

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

"I would like to see more deduplication."

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

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

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

"I would like to see more VM-Aware features in the next release of this solution."

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

More Pure Storage FlashBlade cons

"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."

"Integration with other vendors is not available."

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

"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."

"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."

"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

"This product uses a lot of CPU and network bandwidth. It needs some deduplication features and to use delta for rebalancing."

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

"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."

"Geo-replication needs improvement. It is a new feature, and not well supported yet."

"In the deployment step, we need to create some config files to add Ceph functions in OpenStack modules (Nova, Cinder, Glance). It would be useful to have a tool that validates the format of the data in those files, before generating a deploy with failures."

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

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

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

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.
