Storage design essentials for the cloud
The next important component that needs to be considered is storage. This is the most common characteristic of data store sizing—the number of VMs per data store. Data store sizing is not an easy factor, and it is exclusive to each enterprise. The next factors that should be considered are performance and availability. These, along with decreasing operational cost and effort, are the key drivers of your design.
VMware vSphere Storage DRS (SDRS) provides smart VM assignment, load balancing mechanisms found on I/O, and the obtainability of storage capacity. SDRS helps in drastically reducing the active cost and efforts linked with allocation of VM and monitoring the retail storage infrastructure usage. This is worth considering if you wish to implement Storage DRS.
VMware vSphere, by default, sets the SDRS latency limit to 15 ms. Based on the workload, the unlike types of disks and SLAs need to be considered. You might also need to adjust this value....
