RAID Guideline

Below is the guideline to setup a RAID configuration for Instek Digital™ NVRs and extended storage devices.

1. Number of hard-disc drives per RAID-set.

Hard-disc drive size	RAID-5	RAID-6
< 4TB	≤ 12	≤ 16
≤ 8TB	≤ 8	≤ 12
≤ 10TB	≤ 6	≤ 10

2. Do not exceed two enclosures with the same RAID-set.

3. 7200 RPM hard-disc drive only.

4. Single volume size should NOT exceed 50TB, if so, please create two volumes.

no. Bays	≤ 4TB RAID-5 (max. 12 HDDs/RAID-set)	≤ 4TB RAID-6 (max. 16 HDDs/RAID-set)	≤ 8TB RAID-5 (max. 8 HDDs/RAID-set)	≤ 8TB RAID-6 (max. 12 HDDs/RAID-set)	≤ 10 TB RAID-5 (max. 6 HDDs/RAID-set)	≤ 10 TB RAID-6 (max. 10 HDDs/RAID-set)
8	X 1	X 1	X 1	X 1	4 X 2 RAID-set	X 1
12	X 1	X 1	6 X 2 RAID-set	X 1	X 2	6 X 2 RAID-set
16	8 X 2 RAID-set	X 1	X 2	8 X 2 RAID-set	4 X 4 RAID-set	8 X 2 RAID-set
24	X 2	12 X 2 RAID-set	X 3	X 2	X 4	8 X 3 RAID-set
48	X 4	X 3	X 6	X 6	X 8	8 X 6 RAID-set
60	10 X 6 RAID-set	10 X 6 RAID-set	6 X 10 RAID-set	6 X 10 RAID-set	6 X 10 RAID-set	10 X 6 RAID-set

Remark 1: Instek Digital™ DS2348-JB contains 3 small enclosure, each small enclosure has 16 bays, so it is possible to create 8 (HDDs) x 2 (Raid 5) for each small enclosure.

Remark 2: Instek Digital™ DS2348-JB contains 3 small enclosure, each small enclosure has 16 bays, so it is possible to create 8 (HDDs) x 2 (Raid 5) for each small enclosure or 16 HDDs x 1 Raid 6.

Remark 3: Instek Digital™ DS2360-JB contains 3 small enclosure, each small enclosure has 20 bays, so it is possible to create 10 (HDDs) x 2 (Raid 6) for each small enclosure.
