Introduction

This guide is inteded to show you how to configure 'Just a bunch of disks' (JBOD) on the Cisco

12G SAS Modular RAID Controller in a C-Series server.

Caveats:

* JBOD disks are not able to take advantage of any hardware caching on the RAID controller.

JBOD)

* If caching is required on these disks, then you can put them into a RAID 0 array (striping) and

present this to the OS. Recall that RAID0 has no parity, so please note that the more disks added

to a RAID 0, the larger your failure domain, or the greater the chance of data loss across all disks

due to a single disk failure. This is the nature of RAID 0. Good performance, intolerant of even a

single disk failure. This is acceptable for some applications and use cases however.

Prerequisites

C-Series Server

Cisco 12G SAS Modular Raid Controller

1 or more HDD

Access to CIMC / KVM

Components Used

Cisco C240-M4 running 2.0(6d) CIMC

Cisco 12G SAS Modular Raid Controller running 4.250.00-3632

Configure

As a safety precaution, if you have a pre-existing RAID configuration, please back up the data on

that Virtual Disk (VD) prior to making these changes.

If you have existing Virtual Disk (VD), RAID 1 for instance, that you wish to preserve, its

configuration should be preserved after enabling JBOD, though a reboot is required to enter the

pre-boot RAID configuration menu (CTRL+R) to enable JBOD.
