Re: we need more tapes in the next pool after replacing a primary disk pool with a primary sequential pool

[Mehdi Salehi]

What is the tape drive model? Data transfer rate of LTO4 drives is about
120MB/s, so three drives can carry 3 x 120 = 360 MB/s. (This can be higher
with LTO5 or new IBM tape drives). I don't know your SATA disk
configuration, but you might not gain performance by three parallel
migration processes.
