When designing a SAS Grid Manager architecture, there is a requirement that has always been a critical component: a clustered file system. Over the years, vendors have released versions of these systems that are more robust and SAS has increased the minimum IO requirements, but the basic design has never changed—until now.
With the growing use of SAS on commodity hardware, many organizations are running lots of SAS servers on separate instances of operating system in a SAS infrastructure. This configuration is great for optimizing resources, but when these SAS servers have to share data, then SAS recommends the use of a clustered
For those of you who have followed my SAS Administration blogs, you will know that setting up your IO subsystem (the entire infrastructure from the network/fibre channels in your physical server, across your connections, to the fibre adapters into the storage array, and finally to the physical disk drives in
