Exp3500 Storage Enclosure Overview; Notices And Statements In This Document - IBM DS3500 Installation, User's, And Maintenance Manual

Depending on the model, the DS3524 storage subsystems are shipped with either ac or dc (-48V dc)
power supply and fan units.
DS3524 storage subsystems that are equipped with dc power supply and fan units (1746 model C4T)
supports both NEBS level 3/Telco operating environments and standard Information Technology (IT) and
office environments.
DS3512 and DS3524 storage subsystems that are equipped with ac power supply and fan units support
both NEBS level 3/Telco operating environments and standard IT and office environments.
The IBM System Storage DS Storage Manager version 10 software is also available for the DS3500 storage
subsystem. This storage-management software is designed to help centralize storage management,
simplify partitioning of the DS3500 series storage into as many as 128 virtual servers, and strategically
allocate storage capacity to maximize storage space.
The hot-swap features enable you to remove and replace SAS drives, power supplies, and controllers (in
a dual-controller storage subsystem).
