HP XP7 Disk Array Configuration Guide (H6F56-96003)

Conventions for storage capacity values
HP XP7 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
• 1 EB (exabyte) = 1000
6
bytes
HP XP7 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
• 1 EB (exabyte) = 1024
