Available appliance storage options
The compute nodes do not contain internal disk space on which to store data. Instead, the 5372 Appliance uses the required 5U84 Primary Storage Shelf as the main data storage device. The 5U84 Primary Storage Shelf connects to the 5372 Appliance compute nodes and uses RAID 6 drive sets to protect the stored data.
Note:
RAID 6 is also known as double-parity RAID. It uses two parity stripes on each disk to protect data. RAID 6 allows for two hard disk failures within the RAID disk array before any data is lost.
If additional data storage space is required, you can connect up to three optional 5U84 Expansion Storage Shelves to the existing 5U84 Primary Storage Shelf. The 5U84 Expansion Storage Shelves connect to the 5U84 Primary Storage Shelf using SAS-3 data cables. After connecting the shelves, the disk drives in the 5U84 Expansion Storage Shelf use RAID 6 sets that are controlled by the 5U84 Primary Storage Shelf to protect the stored data.
Note:
Cohesity does not support mixing 4TB and 8TB disk drives within a storage shelf.

*Cohesity 5372 Appliance supports up to 1,056TB (960TiB) of usable MSDP storage capacity. For all storage configurations with an aggregate total of all MSDP pools equaling 960TB or larger, Cohesity strongly recommends upgrading the memory capacity to 1536GB. ** For these storage shelf configurations, Cohesity strongly recommends that you upgrade the memory capacity to 1.5TB due to the increased resource requirements from updated MSDP encryption standards. | |
