Symmetrix DMX-3 Hardware
The GB values shown in Table 12 on page 65 are based on the
following conventions: The GB
2
value is based on 1 GB = 1024 *1024 *
1024 bytes. The GB
10
value is based on 1 GB = 1000 * 1000 * 1000
bytes. Although the open systems GB values are expressed
differently, they are equivalent.
