Capacity and interface

This new IBM 49Y2003 is a 600GB 2.5-inch internal hard drive with a SAS 6Gb/s interface and a 10000 RPM spindle. It carries 16MB of cache and is built for server environments where hot-swap capability is required. The drive delivers an average seek time of 2.9ms and an average latency of 2ms.

Server workload fit

The drive suits administrators who need a 10K SAS spindle for transactional workloads or mixed-use arrays in System x and BladeCenter bays. It is not for buyers who need a 15K spindle for lower latency, who require a larger capacity than 600GB, or whose platform only accepts a different physical or electrical interface.

Deciding specification

The SAS 6Gb/s interface is the single specification that decides compatibility; the drive must connect to a controller or backplane that supports this exact signalling rate and protocol.

Questions about this item

How much noise and heat does the 10000 RPM SAS 6Gb/s drive generate during all-day server operation?

The 10000 RPM spindle and 2.9 ms average seek time mean continuous mechanical activity; expect typical enterprise 2.5" SAS drive acoustics and heat output that requires normal server chassis airflow.

What host interface must my system provide for this 49Y2003 drive to work?

A SAS 6Gb/s host bus adapter or RAID controller with a 2.5" drive bay is required; the drive uses the SAS interface and 16 MB cache for command queuing.

Will this 600 GB 2.5" SAS drive work in an older server that only has 3Gb/s SAS backplanes?

Yes, the SAS 6Gb/s interface negotiates down to 3Gb/s, so the drive will operate at the backplane's maximum link speed while keeping its 10000 RPM performance.
