Adapter cards can be installed in either slot 1 or slot 0; they can be of the same type or as of UCS
Manager 1.3(1), the following mixed configurations are supported:

•
To install an adapter card on the blade server, follow these steps:
Position the adapter board connector above either mother board connector and align the three adapter

captive screws to the posts on the motherboard as shown in callout 1 of
Firmly press the adapter connector into the motherboard connector as shown in callout 2 of

RAID 0 (data striping): Data is striped across all disks in the array, providing fast throughput. There
is no data redundancy, and all data is lost if any disk fails.
RAID 1 (disk mirroring): Data is written to two disks, providing complete data redundancy if one
disk fails. The maximum array size is equal to the available space on the smaller of the two drives.
RAID 5 (disk striping with distributed parity): Data is striped across all disks in the array. Part of
the capacity of each disk stores parity information that can be used to reconstruct data if a disk fails.
RAID 5 provides good data throughput for applications with high read request rates.
RAID 6 (disk striping with distributed parity across two disks): Data is striped across all disks in the
array and two parity disks are used to provide protection against the failure of up to two physical
disks. In each row of data blocks, two sets of parity data are stored.
