Conventions for storage capacity values HP XP storage systems use the following values to calculate physical storage capacity values (hard disk drives): • 1 KB (kilobyte) = 1,000 (103) bytes • 1 MB (megabyte) = 1,0002 bytes • 1 GB (gigabyte) = 1,0003 bytes • 1 TB (terabyte) = 1,0004 bytes • 1 PB (petabyte) = 1,0005 bytes HP XP storage systems use the following values to calculate logical storage capacity values (logical devices): • 1 block = 512 bytes • 1 KB (kilobyte) = 1,024 (210) bytes • 1 MB (megabyte) = 1,0242 bytes • 1 GB (gigabyte) = 1,0243 bytes • 1 TB (terabyte) = 1,0244 bytes • 1 PB (petabyte) = 1,0245 bytes Conventions for storage capacity values 131

Conventions for storage capacity values
HP XP storage systems use the following values to calculate physical storage capacity values (hard
disk drives):
•
1 KB (kilobyte) = 1,000 (10
3
) bytes
•
1 MB (megabyte) = 1,000
2
bytes
•
1 GB (gigabyte) = 1,000
3
bytes
•
1 TB (terabyte) = 1,000
4
bytes
•
1 PB (petabyte) = 1,000
5
bytes
HP XP storage systems use the following values to calculate logical storage capacity values (logical
devices):
•
1 block = 512 bytes
•
1 KB (kilobyte) = 1,024 (2
10
) bytes
•
1 MB (megabyte) = 1,024
2
bytes
•
1 GB (gigabyte) = 1,024
3
bytes
•
1 TB (terabyte) = 1,024
4
bytes
•
1 PB (petabyte) = 1,024
5
bytes
