The bare minimum HDD storage configuration should be 4 enterprise class HDD's. In this scenario, the 4 drives should be divided into 2 independent RAID 1 pairs. The first RAID 1 pair can be small enough to hold just the Windows operating system along with at least 50% additional free space. The second RAID 1 pair should be as large as possible to hold both the video information and the database file. Please see the table below:
| Role | Disk Drives | Configuration | Settings | Partition(s) |
|---|---|---|---|---|
| Boot Volume | 2 Enterprise Class HDD's any RPM/Cache | RAID 1 (Mirror) | n/a | Recommend single partition with NTFS or ReFS to hold Windows Operating System |
| Video/DB Volume(s) | 2 Enterprise Class HDD's, 7200 RPM/256MB Cache | RAID 1 (Mirror) | n/a | Recommend single partition for both video and database |
Ideal Storage:
In the ideal scenario, there are separate RAID arrays for the boot volume, video application volume and the SQL storage volume. Again, only enterprise class HDD's should be considered. This scenario presumes that the database will be stored locally instead of a dedicated Database Server. If you are using an external Database Server, you can disregard the Database Volume row.
