period is the minimum supported. The default Live DB retention period of four hours
has been satisfactory for our tests.
The Archive DB retention period depends on business requirements and can range
from a few weeks to many months. The archived video index files are not verified upon
recording server restart, so server restart is not a consideration for the Archive DB.
Summary of Dell EMC storage and network protocols
Live DB and Archive DB are two distinct repositories with different write
characteristics.
They were evaluated on individual storage platforms and on a single platform in the
following configurations:
l
For the Live DB we tested various Unity and VNX family arrays with both FC and
iSCSI storage protocols.
l
For the Archive DB we tested an Isilon scale-out cluster, Unity arrays, and VNX
family arrays with iSCSI.
l
For a single storage platform including both the Live DB and Archive DB, we tested
a VNX5800
™
with FC and iSCSI.
The following table lists the Dell EMC storage platforms and network protocols
determined to be suitable for each XProtect video database storage tier.
