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

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.It has been pretty reliable throughout the years. As far as capacity is concerned, it can handle most heavy loads.We can have multiple systems within the same file system.Technical support has been very helpful. They provide us with pretty good solutions that we can implement moving forward.Allows us to share files across multiple environments.It is incredibly scalable and stable.Its great servicing high availability. That is what it is used for.

Automatic rebalancing is the feature saving administration time.We are using it as the primary virtualization storage (both for internal corporate users and external customers) for VMware and Hyper-V virtualization platforms.

Maybe it needs integration with HA.They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be.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.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 main issue that we have now is with the encryption. They want to use more metrics in encryption, which is not working very well.

It would be nice to set minimum IOPS per volume, besides just the maximum, to be able to satisfy this demand from customers out-of-the-box, not by calculating number of disks, etc.Ecosystem around the product: There is no built-in system for viewing history data, such as volume IOPS. We have to provide graphing by Prometheus and Grafana, which would be a good new feature in ScaleIO.

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.

ScaleIO is purposely designed to be an enterprise-grade scale-out software-defined storage solution. It applies the principles of server virtualization to standard x86 server flash and hybrid media, turning them into high performance, sharable, pools of storage. Whether your block storage needs are for traditional, modern or cloud workloads, ScaleIO has you covered.
