Moin,
does anybody have a working Plan 9 driver for a SAN hostadapter
(IBM ESS)? I have access to a 5TB IBM ESS which maybe a cool
Venti server.

but where has he mentioned about using a large hole file? he only says
about using a large file.
or am i missing something?
thanks

why?
long back i was thinking that it should be possible use
high-end SCSI disks and use raw disk interface on Linux
and use this setup from plan9 as disk area for kfs.
I was thinking about a TCP/UDP kind of communication
but thats what u9fs does anyway. so i think it is a good idea.
similarly, i think one can use flash disks or thumb drives with
venti to carry plan9 data.
thanks

I meant that I wasn't sure if it is correct to use a large
hole file and fmtarena it with "-z" option instead of zero'ing
the whole unix file (ie, without "-z" option).
I don't doubt that using unix files as sources of kfs/fossil/venti
is a good idea. :)

This might not be correct, but I created a large (~20GB)
hole file on unix and initialized it by fmtarenas
with "-z" option. It worked and saved me time to
zero the whole arena file.

How much disk storage venti can manage?
I'm speaking on my vague memory, but it couldn't do
fmtarena larger than 1TB.
btw, you might be able to use a large unix file on
the IBM ESS mounted via u9fs for a venti arena.
