Smart Array 431 Controller 127695-B21 (1 each)
Smart Array 4250ES Controller (2 each)

Given the 4250 controllers to for disks in drive cages, what would a 431 controller be for?

Thanks

Hi @tultalk1 

The new Smart Array 431 Controller (SA-431) is an intelligent 64-bit array controller for entry level hardware-based fault tolerance with support for up to 14 Wide Ultra3 SCSI hard drives. The SA-431 provides one of the most cost effective alternatives to software-based RAID in the market today, thus lowering entry-level server ownership costs. In addition, the SA-431 is data compatible with all Wide Ultra3 and Wide Ultra2 drives and servers, offering an unparalleled degree of investment protection. Designed and integrated with Compaq entry-level and workgroup servers, this product provides worryfree data protection and gives the customer a single point of contact for all server data storage issues.

The SA-431 has two major advantages over previous generations of entry-level Smart Array controllers:

Advantage Number1: The SA-431 is the first Wide Ultra3 offering in Compaq’s LVD Family of products. Because Wide Ultra3 is data compatible with Wide Ultra2 drives and servers, the SA-431 can offer customers unparalleled investment protection for their Wide Ultra2 and Ultra3 products.

Advantage Number2: The SA-431 achieves greater ease of use through:

1. Online Capacity Expansion: Increases fault tolerant logical drive capacity
2. Online RAID Level Migration: Reduction of downtime during reconfiguration

Thanks for response. But question still remains: Why would the server have 2- 4250 controllers for disks in the drive cages, and what  would the 431

controller be for? 2 redundent 4250's and a 3rd different controller for the same drives??

Very confused as to purpose.

Thanks
