- Hello, Ok, how much data are you getting on a 3590 "K" tape. From reading past posts, I know the Pct Util and Est. Capacity method is suspect at best. All I need is an average you guys have seen usin

- David - A rough visual average that I see on my full tapes is 58 GB, in backup and copy storage pools. (If using HSM, expect much less, because it doesn't Aggregate.) Richard Sims, BU

- What is my problem? I am just going to 3590K. I use client compression on everything. I compress on the tape drives also. I tried to define the format as 3590b, but it doesn't allow me to access the

- FYI, here are my results (using DLT7000 drives) on my three largest storage pools... NT_TAPE is (obviously?) all NT servers, GEN_TAPE is Unix servers, and COLOC_TAPE is collocated Unix servers. I fou

- Not exactly on topic here, but you actually lose throughput when you run compression on both ends of the process. You're better off with tape compression only; the hardware compression algorithm is f
