Hello,
Need advice regarding capacity planning for this site.
The specifics:
Approximately 300Tbytes of disk storage scheduled for backup.
Future backup to include an additional petabyte of data.
Filesystems range in size of 8Tb to 17Tbytes.
Hardware:
Dell R610 with 2 quad processors and 48Gbytes of memory.
Size of the amanda dump area is 2.0Tbytes.
OS is CentOS 5.7.
Amanda is version 3.3.0
Tape is a SUN SL500 with 3 LT05 drives connected to the
R610 via two 2 port/each 8Gbyte fiber cards.
Network is GigE.
Question:
Are the numbers below realistic?
Running the 3 tapes constantly will backup the 300Tbytes
in approximately 1 month.
Anyone have any experience with capacity planning for
a site of this size?
Thanks in advance.
