What is RAID ?
Redundant Array of Independent Disks A way of organizing several disks to provide performance OR resilience:
Tolerant to a disk failure
Types of RAID:
Standard: Level 0 - 5
Vendor Specific: 7 >
Associated technology
Hot plug
Hot Spare

RAID 1E: An LSI specific Level
Mirroring over more than two disks.
During the “Mylex era” this was called Mylex-RAID 6, This is confusing since there is a standard RAID level called RAID6 that has a completely different function

Software RAID Support
Standard O/S Support
Windows 2000/2003 includes RAID 0, 1 & 5
Netware offers RAID 0, 1, 5 & 10
Unixware offers Online Storage Manager (0, 1, 0+1 & 5)
Redhat & Suse Linux Include RAID 0, 1 & 5
Fujitsu-Siemens products
DDM, Duplex Data Manager, Includes RAID 1 w Hot-spare
(Important for MS Cluster configuration )
Implications of Software RAID
RAID 5/3 needs a Math Co-processor (for parity creation)
RAID often not supported on System/boot Partition (Except for FSC DDM)
No instant fail-over ( Except for FSC DDM)
Hot-Plug Support requires HW Control Mechanism.

HW RAID
Cache Policy
Write back
Only enable with BBU or UPS Support
Write Through
Does not use cache
Big Impact on Parity RAID performance
Predictive cache (Read Ahead pattern matching) (for RAID disable it)
Switch off – most requests are not synchronous
Cache Size
Must Support BBU for a weekend.
Larger cache boosts parity raid if using write back policy

Zero Channel RAID
ZCR card must be in correct slot that has the logic to enable it to utilise the onboard SCSI or SAS
Most modern FSC motherboards colour code this blue
Match LSI ZCR with LSI chip on motherboard
Tx150S5,RX200S3 and Tx200S3
Embedded RAID Logic (EMRL): (the Adaptec term for it)
SISL (the term LSI use)
When the ZCR Controller is plugged in the dedicated PCI Slot, the EMRL activates the ChipSelect function for the AIC7901 / 7901 SCSI chip. By activating this function the SCSI Chip isn‘t shown on the PCI Bus any more.
Aditionally the Interrupt channel is changed from a direct connection to the CPU to a connection to the ZCR Controller. So any operation is led directly to the RAID Controller which works off the requests
LSI operates with S2 system boards with LSI chips... they tend to use the term SISL (SCSI Interrupt Steering Logic). Except that a different system board is involved with LSI chips, the operation is equivalent.

Customer Rules
Only FibreCAT SX40 disk drives are released. SAS drives from FibreCAT SX60/80 are not compatible!
Controller is released for FibreCAT SX40 connection only
Controller is not released for internal connection
Max. SAS cable length between controller – box / box – box is 2 m
FibreCAT SX40 must be up before power on of connected controller/server and Controller/server must be powered off before FibreCAT SX40
Redundant path configurations (using two I/O-Modules) are not released
Controller is not released for use as a shared Cluster device in Cluster Configurations
It is strongly recommended to save RAID configurations with MegaCLI
Controller Hotplug is not released
FibreCAT SX40 Hotplug is not released
Tape devices and optical devices (e.g. DVD) are not supported
OS boot from FibreCAT SX40 will be supported with next major release
Replacing a Hot Spare by a new hard disk, this new hard disk stops being handled as Hot Spare in SAS firmware. You need to reconfigure this new hard disk as Hot spare.
