Physical environment

NetBackup Flex Scale nodes must remain unopened and stored in the same location, preferably the datacenter. If cardboard is not allowed in the datacenter, specify where the equipment will be located on the day of installation.

Temperature and cooling requirements

  • American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) A3 and A4 Standards.

  • Operating temperature: (+10°C to +35°C) (+50°F to +95°F)

  • Non-operating temperature: (-30°C to +60°C) (-22°F to +140°F)

  • Operating humidity of Appliance: (8% RH to 90% RH)

  • Non-operating humidity: (5% RH to 95% RH)

Power requirements and consumption

  • Power Cable Specifications: IEC 60320 C14 To IEC 60320 C13 - AC 250 V - 10 A - 6.6 Ft - Black

  • AC power requirements:

    • 100 VAC - 127 VAC at 5.7A

    • 200 VAC - 240 VAC at 2.8A

  • Typical power consumption: 361 watts

  • Maximum power consumption: 500 watts

Rack mounting equipment

NetBackup Flex Scale requires at least four Flex Scale Appliance nodes to form a cluster. Install all the Flex Scale Appliance nodes in an EIA standard rack that is 19 inch (48.26 cm) wide and at least 39.37 inches (100 cm) deep.

Note:

1 inch = 2.54 cm

NetBackup Flex Scale nodes

  • Each node is two rack units (2RU) high.

  • The compute node rails are extensible to 81.28mm (32in). This distance is the maximum depth that is allowed between rack posts.

  • Each node dimensions are as follows:

    • Height: 73.25 cm (28.84 in.)

    • Width: 44.8 cm (17.64 in.)

    • Depth: 8.75 cm (3.44 in.)

    • Weight: 37 kg (81.57 lbs)
