This appendix illustrates the following examples of how to configure storage on unencrypted MD2412 PowerVault (12 * 16 TB Self Encrypting Drives (SEDs)) external storage devices attached to S7 physical hosts.

Configure Storage for Archiver using MD2412
Configure Storage for Decoder using MD2412
Configure Storage for Concentrator using MD2412
Configure Storage for Log Hybrid using MD2412
Configure Storage for Network Hybrid using MD2412
Configure Storage for Endpoint Log Hybrid using MD2412

Note:
The Enable Encryption on Series 6E or Series 7 Hosts topic describes the process to turn on encryption on NW servers and configured storage devices (MD2412).

If the user chooses to enable or turn on encryption before configuring storage (MD2412), the security on the controllers (internal and external) must be enabled and controller security key must be set. To enable the security on the controllers (internal and external) and set the controller security key, refer to Chapter 8 ->Security Key and RAID Management ->Create a security key in the Dell PowerEdge RAID Controller 12 User's Guide.

Once the security key is set, to enable encryption on the external storage, use preferSecure=1 when executing raidNew command to create RAID.

Alternatively, configure the external storage with preferSecure=0 when creating RAID and then follow the steps in Enable Encryption on Series 6E or Series 7 Hosts to turn on encryption.

Configure Storage for Archiver using MD2412

The following scenario configures storage on one, unencrypted, 12-Drive MD2412 PowerVault for an Archiver physical host.

Configure Storage for Concentrator using MD2412

The following scenarios configure storage on one or more unencrypted, 12-Drive MD2412 PowerVault for a Concentrator physical host.

Note: All 12 drives on PowerVault MD2412 are HDDs. This is also used as storage for concentrator service whereas older PowerVault MD1400 for concentrator storage has mixed drive configuration with HDDs and SSDs. Since MD2412 has no support for SSDs and the concentrator service requires atleast 2 SSDs for index database, SSDs are to be installed on the concentrator physical host in slots 4 through 9 with a minimum of 3 drives.

Supported SSD configurations on the S7 concentrator host -
- 3 drives - slots 4,5 and 6 - RAID 5
- 6 drives - slots 4,5,6,7,8 and 9 - RAID 6
- 3 Drives + 3 Drives - RAID 5, initially 3 drives are installed followed by extension with another 3 drives.

The SSD drive packs are available in two sizes - 3 * 3.2 TB or 3 * 7.68 TB. In the following examples, the drive pack of 3 * 3.2 TB is used. When a larger drive pack (3 * 7.68 TB) is used, the virtual drives are larger in size.

Scenario 1:

3 SSD drives are added to the Concentrator physical host. Host is connected to one unencrypted 12-Drive MD2412 PowerVault.
