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.

Quotes from Members

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

Pros

"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."

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

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

"I rate this product ten out of ten."

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

"We use GPFS Scale for parallel file access, the file management, and it's an essential part of our operations."

"It is a scalable solution."

"Its great servicing high availability. That is what it is used for."

More IBM Spectrum Scale pros

"The solution is simple to configure and provides good performance and less footprint."

"The single management panel is the main feature that is wonderful for the customer."

"The best part of the solution is that you can actually scale up to a large number of operating systems without additional hardware."

"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."

"This is an easy-to-use product for adding flexibility to your storage solution."

"VMware Software Defined Storage gives higher availability against data corruption."

"The most valuable features of the solution are that it is easy to deploy and the support is really good."

"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."

Cons

"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."

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

"The solution's pricing could be better."

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

"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

"I'd like to see improved hardware compatibility"

"Simplifying the licensing model and making it cheaper would improve the solution."

"It doesn't have the ability to be deployed on any kind of hardware and network connectors."

"There is room for more integrations and plugins into more storages."

"VMware Software Defined Storage should include a shared database on a standard version."

"The license model of the product is an area of concern where improvements are required."

"The performance is not as good as some competing products and reporting can be improved."

"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."

Pricing and Cost Advice

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

"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."

"VMware Software Defined Storage is a slightly expensive solution."

"The product is quite expensive and is among the most expensive for this type of solution."

"A single socket costs you around US $6,000 for three years. At a minimum, you have a three load cluster for a medium or enterprise-scale company. It can get quite expensive because you're likely to need four to six sockets on the other side. It comes to around $30,000."

"The solution is very expensive."

"I believe there is a yearly licensing fee of around $2000 - $5000. I don't think there are additional costs above that but it depends on the type of infrastructure you're booting."

Overview

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.
