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.

Pros

"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."
"We use GPFS Scale for parallel file access, the file management, and it's an essential part of our operations."
"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."
"The profile share is a valuable feature."
"GPFS monitoring is the best feature."
"We can have multiple systems within the same file system."
"The most valuable feature is the ability to share files across different platforms."
"VMware Software Defined Storage gives higher availability against data corruption."
"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 solution is simple to configure and provides good performance and less footprint."
"This is an easy-to-use product for adding flexibility to your storage solution."
"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."
"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

"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."
"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."
"I wish there were some graphical user interface to access the GPFS file system creation and monitoring."
"Maybe it needs integration with HA."
"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."
"Integration with other vendors is not available."
"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."
"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 performance is not as good as some competing products and reporting can be improved."
"I'd like to see improved hardware compatibility"
"VMware Software Defined Storage should include a shared database on a standard version."
"Simplifying the licensing model and making it cheaper would improve the solution."
"The license model of the product is an area of concern where improvements are required."
"It doesn't have the ability to be deployed on any kind of hardware and network connectors."
"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."
"There is room for more integrations and plugins into more storages."
 

Pricing and Cost Advice

"The solution is costly but reliable."
"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 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."
"VMware Software Defined Storage is a slightly expensive solution."
"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."
