Note: Decrease the maximum system temperature by 1°C for every 175 m increase in altitude.

Preparing your environment

The following tables list the physical characteristics of a SAN Volume Controller 2145-SV2 node.

Dimensions and weight

Use the parameters that are shown in Table 4 to ensure that space is available in a rack capable of supporting the node.

Table 4. Dimensions and weight
Height Width Depth Maximum weight
87 mm (3.4 in.) 447 mm (17.6 in) 746 mm (30.1 in) 25 kg (55 lb) to 30 kg (65 lb) depending on configuration

Additional space requirements

Ensure that space is available in the rack for the additional space requirements around the node, as shown in Table 5.

Table 5. Additional space requirements
Location Additional space requirements Reason
Left side and right side Minimum: 50 mm (2 in.) Cooling air flow
Back Minimum: 100 mm (4 in.)

If the cable-management arm is used, allow 177 mm (7 in.)

 Cable exit

Maximum heat output of each SAN Volume Controller 2145-SV2 node

The node dissipates the maximum heat output that is given in Table 6.

Table 6. Maximum heat output
Model Heat output per node
SAN Volume Controller 2145-SV2 Typical configuration: 1808 BTU per hour (530 watts)
2145-SA2 Typical configuration: 1112 BTU per hour (326 watts)

Acoustical declaration with noise hazard notice

Table 7 summarizes the declared noise emission values for SAN Volume Controller 2145-SV2 and 2145-SA2 systems.

Notes:
  1. Declared level LWA,m is the upper-limit A-weighted sound power level. Declared level LpA,m is the mean A-weighted sound pressure level measured at the 1-meter bystander positions.
  2. The statistical adder for verification, Kv, is a quantity to be added to the declared mean A-weighted sound power level, LWA,m such that there will be a 95% probability of acceptance, when using the verification procedures of ISO 9296, if no more than 6.5% of the batch of new equipment has A-weighted sound power levels greater than (LWA,m + Kv).
  3. The quantity LWA,c (formerly called LWAd), can be computed from the sum of LWA,m and Kv.
  4. All measurements made in conformance with ISO 7779 and declared in conformance with ISO 9296.
  5. B, dB, abbreviations for bels and decibels, respectively. 1 B = 10 dB.
  6. Notice: Government regulations (such as those prescribed by OSHA or European Community Directives) may govern noise level exposure in the workplace and may apply to you and your server installation. The actual sound pressure levels in your installation depend upon a variety of factors, including the number of racks in the installation; the size, materials, and configuration of the room where you designate the racks to be installed; the noise levels from other equipment; the room ambient temperature, and employees' location in relation to the equipment. Further, compliance with such government regulations also depends upon a variety of additional factors, including the duration of employees' exposure and whether employees wear hearing protection. IBM recommends that you consult with qualified experts in this field to determine whether you are in compliance with the applicable regulations.
  7. Sound Pressure Level given is greater value of front and rear measurements.
