First Steps: Virtual Machine Storage
How critical is the virtual machine?
What are its performance requirements?
What are its availability requirements?
What are its Point-in-Time (PiT) restoration
What are its backup requirements?
What are its replication requirements?
In short, what “tier” storage does that virtual
machine belong on?
What Are Some of the Tiers?
High Tier: High performance, high availability,
often built in snapshots, to facilitate backups and
Point-in-Time (PiT) restorations, replication, full
controller redundancy, fibre drives. High cost
Mid Tier: Mid-range performance, lower
availability, MAYBE snapshots, some controller
redundancy, SCSI drives. Medium cost spindles
Lower Tier: Low performance, little internal
storage redundancy, low end SCSI drives or SATA.
Low cost spindles
Technology changes and push higher tier
features to a lower tier: Better, faster,
A virtual machine may change tiers
throughout its “lifecycle”, due to changes in
criticality or changes in technology
Criticality is relative, and may change for a
variety of reasons, including changes in the
organization, operational processes,
regulatory requirements, disaster planning,
