System Components
All components are configured in redundant pairs to prevent system failure.
All the components can be added, removed, or replaced while the storage
system is in operation.
The Virtual Storage Platform can be configured with two types of drive
chassis:
• An LFF DKU (disk unit) chassis, which contains up to 80 LFF (3-1/2 inch)
HDD or SSD drives
• An SFF DKU (disk unit) chassis, which contains up to 128 SFF (2-1/2
inch) HDD or SSD drives
The following illustration shows the rear view of a DKU drive chassis. The
