Configuration guidelines:
• A dedicated on-board or add-in RAID controller must be used with a minimum of 128 MB of battery backed
cache.
• Increasing the number of physical drives increases the overall fault tolerance of the disk array.
• Use multi-channel controllers connected to discrete drive bays or backplanes.
• Use multi-channel controllers connected to discrete drive bays or backplanes.
Note:
Multiple controller channels can be of significant advantage when there are multiple drive bays and backplane
connections. Each channel of the controller can connect to a separate backplane connection, and arrays split
between the channels and backplanes can take advantage of the increased throughput as well as increased
resiliency.

resiliency.
• Two channels per external storage enclosure.
• Multiple external storage enclosures are desirable (when needed) for increased performance and fault tolerance.
• External storage enclosures with dedicated RAID controllers are supported with MCS server systems.

• External storage enclosures with dedicated RAID controllers are supported with MCS server systems.
Supported configurations:
• Fibre Channel is supported only in a point-to-point topology deployment.
• Dedicated on-board or add-in RAID controllers are required to use any of the RAID levels supported.
• RAID 1 (Mirroring and Duplexing) – This is the minimum RAID level for all critical Unified ICM and Unified
• Dedicated on-board or add-in RAID controllers are required to use any of the RAID levels supported.
• RAID 1 (Mirroring and Duplexing) – This is the minimum RAID level for all critical Unified ICM and Unified
typically used for boot drives on all servers to prevent loss of data and down time in the event of a disk failure.
