Understanding RAID Options
When installing the Cisco SRE-V application on a Cisco SRE 900 or 910 Service Module, you can choose to store data files on local Redundant Array of Inexpensive Disks (RAID). The available RAID mode options are: RAID 1, RAID 0, and non-RAID.
Note RAID is not supported on the Cisco SRE 700 or 710 Service Module. It is supported on the Cisco SRE 900 and 910 Service Modules only.
Table 4-1 provides a summary of the RAID options.
Table 4-1 Summary of RAID Options

|
|
RAID 1 |
Mirrored set of disk drives, where the data in both the disks is identical. |
•High availability •Fault tolerance •Hot-swapping |
•Storage—465 GB •Small performance impact |
RAID 0 |
Data is stored evenly in stripe blocks across two or more disks without redundancy (mirroring). The data in both the disk drives is different. |
•Storage—927 GB •Double performance |
•No error checking •No fault tolerance •No hot-swapping •No redundancy |
Non-RAID |
Disk drives of a computer are not configured as RAID. Also referred to as JBOD. |
•Portable |
•No error checking •No fault tolerance •No hot-swapping •No redundancy |
See the following sections for more information:
•RAID 1
•RAID 0
•Non-RAID
RAID 1
RAID 1 does the following:
•Creates a mirrored set of disk drives, where the data in both the disk drives is identical. See Figure 4-1.
•Provides high availability. If one disk drive fails, the other disk drive takes over, preserving the datastore.
•Supports fault tolerance and hot-swapping. When one disk drive fails, you can remove the faulty disk drive and replace it with a new disk drive. See the "Hot-Swapping the Faulty RAID 1 Disk Drive" section.
Compared to RAID 0, there is less storage space with RAID 1 because only half of the total potential disk storage space (465 GB) is available. This leads to a small impact on performance.
Figure 4-1 shows that in RAID 1, the data in disk 0 and disk 1 is identical (mirrored).
Figure 4-1 RAID 1 Option—Data in Disk 0 and Disk 1 Is Identical
RAID 0
With RAID 0, the data is stored evenly in stripe blocks across two disk drives without redundancy (mirroring). The data in both the disk drives is different. See Figure 4-2.
Compared to RAID 1, RAID 0 provides additional storage because both the disk drives (927 GB) are used to store data. The performance is improved by two times because the read and write operation occurs in parallel within the two disk drives.
However, there is no fault tolerance, error checking, or hot-swapping. If one disk drive fails, the data in the entire array is destroyed. Because there is no error checking or hot-swapping, the array is susceptible to unrecoverable errors.
Figure 4-2 shows that in RAID 0, the data in disk 0 and disk 1 is different. The data is evenly divided across Disk 0 and Disk 1 without redundancy.
Figure 4-2 RAID 0—Data in Disk 0 and Disk 1 Is Different
Non-RAID
When the disk drives of a computer are not configured as RAID, the computer is in non-RAID mode. Non-RAID mode is also referred to as Just a Bunch of Disks or Just a Bunch of Drives (JBOD). Non-RAID mode does not support fault tolerance, error checking, hot-swapping, or redundancy.

About Upgrading and Migrating
When you migrate the software, you perform a clean install of the Release 2.0 software and keep only the datastore content. To migrate the software, use the keep-ds argument.
When you upgrade the software, you perform a clean install of the Release 2.0 software and keep the VMware vSphere Hypervisor host configuration data as well as the datastore content. To upgrade the software, use the upgrade argument. To keep the VMWare vSphere Hypervisor host configuration data, use the upgrade argument.
If you use both the keep-ds and the upgrade arguments, the system uses the upgrade argument and ignores the keep-ds argument.
Migrating the Cisco SRE-V Software from Release 1.0 or 1.1 to Release 2.0
Before You Begin
•Download the appropriate version of the Cisco SRE-V upgrade software. See the "Downloading the Cisco SRE-V Software" section.
