Explanation
EMC recommends the following settings for all virtual disks:
Disk Provisioning: Thick Provision Eager Zeroed.
Location: A different datastore than the VM.

Explanation/Reference:
If a single Storage Processor (SP) comes up in Service Mode, in Unisphere, you need to reboot the SP to
return it to Normal Mode.

Explanation
Asynchronous remote replication requires a replication interface be created on each SP on the system.
For asynchronous replication, replication is performed over Ethernet interfaces configured on the system. On EMC Unity physical systems, the onboard 10GbE BaseT ports, CNA ports with Ethernet personality, or Ethernet ports located on I/O modules can be used for replication. In UnityVSA systems, any I/O port can be used for asynchronous replication.

Recovery Point Objective (RPO) is an industry accepted term that indicates the acceptable amount of data, measured in units of time, that may be lost in a failure. When you set up an asynchronous replication session, you can configure automatic synchronization based on the RPO. You can specify an RPO from a minimum of 5 minutes up to a maximum of 1440 minutes (24 hours).
