Intel® Server Board S2600WT TPS rate. RAID 5 is well suited for applications that require high amounts of storage while maintaining fault tolerance. Note: RAID configurations cannot span across the two embedded AHCI SATA controllers. By using Intel® RSTe, there is no loss of PCI resources (request/grant pair) or add-in card slot. Intel® RSTe functionality requires the following:  The SW-RAID option must be enable in BIOS Setup  Intel® RSTe option must be selected in BIOS Setup  Intel® RSTe drivers must be loaded for the installed operating system  At least two SATA drives needed to support RAID levels 0 or 1  At least three SATA drives needed to support RAID levels 5 or 10 With Intel® RSTe SW-RAID enabled, the following features are made available:  A boot-time, pre-operating system environment, text mode user interface that allows the user to manage the RAID configuration on the system. Its feature set is kept simple to keep size to a minimum, but allows the user to create and delete RAID volumes and select recovery options when problems occur. The user interface can be accessed by pressing the keys during system POST.  Provides boot support when using a RAID volume as a boot disk. It does this by providing Int13 services when a RAID volume needs to be accessed by MS-DOS applications (such as NTLDR) and by exporting the RAID volumes to the System BIOS for selection in the boot order  At each boot up, provides the user with a status of the RAID volumes 5.6.2 Intel® Embedded Server RAID Technology 2 (ESRT2) Features of ESRT2 include the following:  Based on LSI* MegaRAID Software Stack  Software RAID with system providing memory and CPU utilization  RAID Level 0 - Non-redundant striping of drive volumes with performance scaling up to 6 drives, enabling higher throughput for data intensive applications such as video editing.  Data security is offered through RAID Level 1, which performs mirroring.  RAID Level 10 provides high levels of storage performance with data protection, combining the fault- tolerance of RAID Level 1 with the performance of RAID Level 0. By striping RAID Level 1 segments, high I/O rates can be achieved on systems that require both performance and fault-tolerance. RAID Level 10 requires 4 hard drives, and provides the capacity of two drives  Optional support for RAID Level 5 o Enabled with the addition of an optionally installed ESRT2 SATA RAID 5 Upgrade Key (iPN RKSATA4R5) o RAID Level 5 provides highly efficient storage while maintaining fault-tolerance on 3 or more drives. By striping parity, and rotating it across all disks, fault tolerance of any single drive is achieved while only consuming 1 drive worth of capacity. That is, a 3 drive RAID 5 has the capacity of 2 drives, or a 4 drive RAID 5 has the capacity of 3 drives. RAID 5 has high read transaction rates, with a medium write rate.

rate. RAID 5 is well suited for applications that require high amounts of storage while maintaining
fault tolerance.
Note: RAID configurations cannot span across the two embedded AHCI SATA controllers.
By using Intel
®
RSTe, there is no loss of PCI resources (request/grant pair) or add-in card slot. Intel
®
RSTe
functionality requires the following:
The SW-RAID option must be enable in <F2> BIOS Setup
Intel
®
RSTe option must be selected in <F2> BIOS Setup
Intel
®
RSTe drivers must be loaded for the installed operating system
At least two SATA drives needed to support RAID levels 0 or 1
At least three SATA drives needed to support RAID levels 5 or 10
With Intel
®
RSTe SW-RAID enabled, the following features are made available:
A boot-time, pre-operating system environment, text mode user interface that allows the user to
manage the RAID configuration on the system. Its feature set is kept simple to keep size to a
minimum, but allows the user to create and delete RAID volumes and select recovery options when
problems occur.
The user interface can be accessed by pressing the <CTRL-I> keys during system
POST.
Provides boot support when using a RAID volume as a boot disk. It does this by providing Int13
services when a RAID volume needs to be accessed by MS-DOS applications (such as NTLDR) and by
exporting the RAID volumes to the System BIOS for selection in the boot order
At each boot up, provides the user with a status of the RAID volumes

Intel

Embedded Server RAID Technology 2 (ESRT2)
Features of ESRT2 include the following:
Based on LSI* MegaRAID Software Stack
Software RAID with system providing memory and CPU utilization
RAID Level 0
- Non-redundant striping of drive volumes with performance scaling up to 6 drives,
enabling higher throughput for data intensive applications such as video editing.
Data security is offered through
RAID Level 1
, which performs mirroring.
RAID Level 10
provides high levels of storage performance with data protection, combining the fault-
tolerance of RAID Level 1 with the performance of RAID Level 0. By striping RAID Level 1 segments,
high I/O rates can be achieved on systems that require both performance and fault-tolerance. RAID
Level 10 requires 4 hard drives, and provides the capacity of two drives
Optional support for
RAID Level 5
o
Enabled with the addition of an optionally installed ESRT2 SATA RAID 5 Upgrade Key (
iPN -
RKSATA4R5
)
o
RAID Level 5
provides highly efficient storage while maintaining fault-tolerance on 3 or more
drives. By striping parity, and rotating it across all disks, fault tolerance of any single drive is
achieved while only consuming 1 drive worth of capacity. That is, a 3 drive RAID 5 has the
capacity of 2 drives, or a 4 drive RAID 5 has the capacity of 3 drives. RAID 5 has high read
transaction rates, with a medium write rate. RAID 5 is well suited for applications that require
high amounts of storage while maintaining fault tolerance
