RSTe vs ESRT2 [CentOS 6]



I have Server Board S2600GL with RAID C600 chipset and Upgrade Key: RKSATA8R5 (Intel RSTe or Intel ESRT2 8 ports SATA RAID 0, 1, 10, 5).

Installed SATA hard drives (8 pieces) with RAID 5.

Historically, this situation are :

Installed CentOS 6.5 (64-bit) _without_ special Intel RAID drivers.

In BIOS menu "Mass Storage Configuration" set:

AHCI Capable SATA controller = Disabled

SAS/SATA Capable controller = INTEL RSTe

All worked fine since summer 2013.

Details in attached file.

After a failure of one hard drive (everything is fine now) I found this information:

This applies to: Intel® Server Board S2600GL

"Red Hat Enterprise Linux 6.3* with KVM (32-bit & 64-bit) only supported in AHCI or ESRT2 mode"

My questions are:

1. whether it is necessary immediately migrate whole server to another location and reconfigure the current Intel RSTe controller mode to ESRT2 mode (and migrate server back) ?

2. Where to find the Intel ESRT2 drivers for CentOS 6.5 (64-bit) ?

3. If I do not switch to ESRT2 mode and the driver is not installed (ie leave it as is), what awaits me in the future?

Intel(R) ESRT2 has support for the Intel(R) C600 chipset on both AHCI Capable SATA Controller and SATA/SAS Capable Controllers. ESRT2 supported operating systems are Red Hat Enterprise Linux and SUSE Linux Enterprise Server. According to the page you reference, for CentOS* 6.x we have only tested under a basic installation scenario. Intel does not provide technical support for CentOS* 6.x. You should contact the related open source community for support.

Currently we only support RSTe under Windows* operating systems.

Because of this we can't fully answer your questions.
