The small disk enclosure design concept is described.
The design concept is based on an enclosure subsystem together with a set of plug-in modules. A typical
enclosure system, as supplied, includes the following:
• A small disk enclosure contains:
– A mid plane PCB
– An integral, front flange mounted operator’s (ops) panel.
• Two 580W, 100-240V AC power cooling modules (PCMs)
• One I/O module: SBB Primary Interface
• One I/O blank: SBB Secondary Interface
• 12 - 3.5" SAS HDDs
• A rail kit for rack mounting
• A documentation package
• All feature order components
