Actual values at a typical I/O condition. (Random Read and Write, 50 IOPSs for HDD, 2500 IOPSs for SSD, Data
Length: 8Kbytes). These values may increase for future compatible drives.

AV411B Base 2.5in Drive Chassis does not include power supplies consequently demands zero (0) kVA and
generates no (0) kW heat. When AV459A/AU DKU Pow supplies are installed in an AV411B/BU, then the chassis
fans will demand same power and heat as AV412B/BU.
6
Maximum values with all fans rotate at maximum.
Equipment noise
The acoustic emission values [loudness in dB (A)] for the P9500 disk array disk array are:
• Front/rear = 65 dB (A)
• Both sides = 65 dB (A)
Service clearance, floor cutout, and floor load rating
This section describes the service clearance requirements for the P9500 disk array, based on
the floor load rating and the clearance and required floor cutouts for cabling. The figures and
tables that provide this information are listed in the following table.

NOTE: For safe and efficient maintenance operations, clearance (c) should be made as large
as possible. Actual clearances for installation should be determined after consulting with the
site/facilities manager, as the clearances can vary, depending on building conditions. Although
all disk chassis come pre-installed, up to 1420 mm of clearance may be required at both front
and back for a disk chassis replacement.
The figures in this section are not drawn to scale.
Single rack configuration
The following figure and table show the service clearances and floor load rating for a single rack
configuration.
