Overview 15
Scalability
The disk array is scalable to accommodate your current and future storage
capacity needs.
Figure 1 shows the disk array equipment racks.
In the basic configuration, the disk array consists of one primary 19-inch
rack containing the following:
• One disk controller with control panel and SVP blade PC
• One 60-disk chassis, consisting of two 30-drive HDU boxes
• Mix board with disk adapters and host ports
• Power supplies, power distribution units (PDUs), backup batteries,
power cords, and cabling
You can expand the primary rack as follows:
• Add one 60-disk chassis containing two 30-drive HDU boxes to the
top space of the primary rack. This provides a total of up to 120 drives
After expanding the primary rack, you can add a second 19-inch rack with
additional disk units as follows:
• Add one 60-disk chassis to the second rack for a total of up to 180
drives
• Add a second 60-disk chassis to the second rack for a total of up to 240
drives
Disk array basic storage includes disk chassis R0 in the primary rack. Add
more disk chassis in the order shown in Figure 1: R1, R2, R3.
Your HP support representative can add disk chassis and disk drives online
with no interruptions to applications or hosts.
Note: The initial release of the XP10000 disk array may not include a second
rack. This option is expected to become available soon after release.
