One of the great features that VMware vSphere has is Storage DRS, that as we can imagine, is similar to traditional DRS but with storage, This is, instead of distributing the count (CPU, RAM…), with Storage DRS we will be able to distribute the load of the datastores, balancing so much for performance (Latency to Datastore) and by space used. With this we will have fully distributed the load in terms of disk!
On VMware, One way to be able to catalog our storage is by using Storage policies. With them, among other things, We can initially create tags to tag our datastores, and then create storage policies based on certain conditions that the datastores meet. With this, we will be able to stop worrying about where we store the virtual machines individually and we will try to manage them based on their criticality, yield…
vSphere 5 vSphere Storage Appliance (VSA), a solution designed for small businesses that do not have the budget to purchase a storage array and want to have high availability in terms of storage or have features such as HA or VMotion, DRS… Thanks to this small appliance that runs on each host and through the VSA Manager, we will have the local datastores replicated between the ESXi hosts.
It is one of the new features of vSphere 5, It is a pool of datastores that will help us to manage the datastores together, always obtaining the best result to locate a virtual machine and thus have a higher performance at the disk level since it will always offer us recommendations to choose the lightest datastore. It will also analyze and generate recommendations for moving virtual machines between the different datastores in the cluster.
