Dell EMC storage considerations for Milestone XProtect
Corporate
To successfully design and implement a Milestone XProtect Corporate system, you
need to consider many aspects of the system, including networks, cameras, storage,
and more. This section presents storage considerations and recommendations you
should take into account when deploying a Milestone XProtect Corporate system on
Dell EMC storage platforms.
Video Flow
There are many Dell EMC storage platform options for each storage tier. The Live DB
can be direct-attached storage (DAS), such as FC or iSCSI block storage. The Archive
DB can be DAS if the storage requirement is minimal, and network-attached storage
(NAS), FC, or iSCSI for virtualized server implementations and more substantial video
storage requirements.
The following figure illustrates the video flow using NAS, DAS, and storage-area
network (SAN).

Video is initiated at the camera and XProtect initially places that video in the Live DB.
Milestone recommends a retention period of from 2 to 24 hours for video in the Live
DB, as outlined in
Retention periods .
XProtect moves video files at rest from the Live DB storage tier to the Archive DB
storage tier at regular intervals. The Archive DB stores each video file until that file’s
full retention time has expired.
Live DB
XProtect’s Live DB write algorithm is optimized for block storage. Therefore, the Live
DB works best with the server’s internal DAS, or with external FC or iSCSI storage
arrays such as the VNX, VSS, and VNXe series.
Internal DAS storage is ideal for small implementations with a few servers. As an
installation grows, the need to optimize storage for reliability, scalability,
manageability, and rack space increases. In larger environments, and in virtualized
