Scalability
The Virtual Storage Platform is highly scalable and can be configured in
several ways as needed to meet customer requirements:
•The minimum configuration is a single rack containing one controller

• A small VSP system could include a single rack containing one controller
chassis and one or two disk drive or flash chassis.
• A mid-sized VSP system could include one to three racks containing one
controller chassis and up to eight drive chassis. A LFF drive chassis can
contain up to 80 3-1/2 inch disk drives. A SFF drive chassis can contain
a combination of up to a total of 128 2-1/2 disk and SSD data drives. An
