About the appliance and the storage shelves
The Cohesity 5372 Appliance is a hardware and software storage system designed for large workloads. It provides high performance with multiple service offerings and gets deployed in less than 60 minutes and scales up to a total of 1,920 TiB (2,112 TB) of usable backup capacity.
The Cohesity 5372 appliance is available as a single-node or a two-node appliance.
The Cohesity 5372 appliance and storage shelves provide storage capacity in several configurations. The 5372 compute node does not provide any storage. The 5U84 storage shelves provide storage capacity for the appliance system. You must have a Primary Storage Shelf that connects to the compute node. You can add up to three optional Expansion Storage Shelves for additional storage.
The Cohesity 5372 high availability (HA) configuration includes two compute nodes, one required Primary Storage Shelf, and up to three optional Expansion Storage Shelves.
The Cohesity 5372 Appliance supports the following software:
Flex Appliance release 7.0 and above
Before you install the hardware, refer to the following section for important details about the dimensions of the hardware.
See Dimensions and determining rack locations.
The compute node is two rack units (2RU) high.
Each storage shelf is 5RU high and contains 2 drawers with 42 disk drive slots per drawer.
The rear of the Primary Shelf includes two redundant RAID controller I/O modules. The Expansion shelves contain two I/O modules for connectivity to the Primary Shelf and to other Expansion shelves. Half capacity storage shelves are also available for the 5372 appliances.
The Flex 5372 appliance model only supports Self-encrypting drives (SED) for both the head node and the Storage shelves. This enhances the data security and protection capability of the Flex appliances by keeping data stored on the appliance safe at all times, including at rest. Self-encrypting drives (SEDs) or Full Disk Encryption (FDE) technology encrypts data as it is written to the disk. Each disk has a disk encryption key (DEK) that is to be set at the time of deployment using a passphrase which is compliant to the UTF-8 standard. The disk uses the DEK to encrypt data as it writes, and then to decrypt the data as it is read from disk. The operation of the disk, and its encryption and decryption, is transparent to the application, host and end user who are reading and writing data.
With the required 5U84 Primary Storage Shelf, the compute node operates at 220 VAC at 3.1 A with C13 and C14 connectors. The Storage shelves operate with C19 and C20 connectors.
