Storage server components
The following sections show the components of the storage server.
The hot-swap features of the storage server enable you to remove and replace hard
disk drives, power supplies, RAID controllers, and fans without turning off the
storage server. Therefore, you can maintain the availability of your system while a
hot-swap device is removed, installed, or replaced.

IBM TotalStorage DS4000: Hardware Maintenance Manual
FAStT200 storage server (Model 3542-1RU) and the IBM FAStT200 HA
storage server (Model 3542-2RU). Model-specific information is noted where
applicable.
Environment
v Air temperature:
– Storage server on:
10° to 35° C
(50° to 95° F)
Altitude: 0 to 914 m
(3000 ft.)
– Storage server on:
10° to 32° C
(50° to 90° F)
Altitude: 914 m (3000 ft.)
to 2133 m (7000 ft.)
v Humidity:
– 8% to 80%
Acoustical noise emissions values
For open bay (0 drives installed) and typical
system configurations (8 hard disk drives
installed):
v Sound power (idling):
– 6.3 bels (open bay)
– 6.5 bels (typical)
v Sound power (operating):
– 6.3 bels (open bay)
– 6.8 bels (typical)
v Sound pressure (idling):
– 47 dBA (open bay)
– 65 dBA (typical)
v Sound pressure (operating):
– 47 dBA (open bay)
– 68 dBA (typical)
These levels are measured in controlled
acoustical environments according to ISO
7779 and are reported in accordance with ISO
9296. The declared sound power levels
indicate an upper limit, below which a large
portion of machines operate. Sound pressure
levels in your location might exceed the
average 1-meter values stated because of
room reflections and other nearby noise.
