SAN Storage Backup Considerations
ESXi and SAN Use Cases
When used with a SAN, ESXi can benefit from multiple vSphere features, including Storage vMotion,
Distributed Resource Scheduler (DRS), High Availability, and so on.
Using ESXi with a SAN is effective for the following tasks:
Storage consolidation
and simplification of
storage layout
If you are working with multiple hosts, and each host is running multiple
virtual machines, the storage on the hosts is no longer sufficient. You might
need to use external storage. The SAN can provide a simple system
architecture and other benefits.
Maintenance with zero
downtime
When performing ESXi host or infrastructure maintenance, use vMotion to
migrate virtual machines to other host. If shared storage is on the SAN, you
can perform maintenance without interruptions to the users of the virtual
machines. Virtual machine working processes continue throughout a
migration.
Load balancing You can add a host to a DRS cluster, and the host's resources become part
of the cluster's resources. The distribution and use of CPU and memory
resources for all hosts and virtual machines in the cluster are continuously
monitored. DRS compares these metrics to an ideal resource use. The
ideal use considers the attributes of the cluster's resource pools and virtual
machines, the current demand, and the imbalance target. If needed, DRS
performs or recommends virtual machine migrations.
Disaster recovery You can use VMware High Availability to configure multiple ESXi hosts as a
cluster. The cluster provides rapid recovery from outages and cost-effective
high availability for applications running in virtual machines.
Simplified array
migrations and storage
upgrades
When you purchase new storage systems, use Storage vMotion to perform
live migrations of virtual machines from existing storage to their new
destinations. You can perform the migrations without interruptions of the
virtual machines.
Speciļ¬cs of Using SAN Storage with ESXi
Using a SAN with an ESXi host differs from a traditional SAN use in several ways.
