You will probably want to test with and without hardware compression, and see which works best for your configuration. Some vendors are optimistic about their compression and should really be claiming 1.5:1 instead of 2.1:1. Not using hardware compression also allows you to choose whether to compress on the server or the client, or not at all. My guess on the filemark size is that it is an artifact of hardware compression and not a concern. You can probably turn compression on and off using the `mt` command. A search of the mailing list archive for 'hardware compression' should return more useful information. -----Original Message----- From: Bradley Glonka [mailto:[EMAIL PROTECTED]] Sent: Thursday, December 28, 2000 2:52 PM To: [EMAIL PROTECTED] Subject: VXA Tape V17 Anyone using Ecrix VXA V17 tapes? I found this config in the faq-omatic I have a question: This drive is supposed to write 66gb with hardware compression. This config only reflects "length 30609 mbytes" about half of that. define tapetype VXA { comment "Ecrix VXA-1 V17" length 30609 mbytes filemark 2141 kbytes speed 2892 kbytes } I ran the tapetype utility with hardware compression turned on and got some differnt results. define tapetype VXA { comment "Ecrix VXA-1 V17" length 27379 mbytes filemark 8872 kbytes speed 2540 kbytes } - how do I take advantage of hardware compression? - Is the large differnce in filemarks a problem? Thanks brad
