Using a RAID box for innd news spools -- advice sought

Post by Rob Tann » Wed, 16 Oct 1996 04:00:00



Hi all,

Anyone have experience running news with RAID spools?

I'm moving my news server from an underpowered Sparc 10 to a new Ultra
with lots of RAID disk.  For news, is it better to build multiple small
partitions for the spool (as is the only available case when using
quad-packs and other non-RAID disk technologies), or is it better to build
a single large partition of say 16GB for the spool?  Or does it matter one
way or the other?  

Thanx,
Rob

None of it really matters, except that without a log-structured filesystem on
top of it that can do log writes in an optimal size for the RAID, news is
optimally lossy for RAID systems.

The other option is a hardware RAID controller with *lots* of NVRAM for write
rescheduling.  Just make sure it's *NV*RAM before you turn write caching on.

1. Raid using single disks vs a Raid Box

We are in the process of deciding how to configure disks for an E3000
which we want to use as a file server. Two possibilities exist to do
this, but independent disks attached seperatly to the SCSI bus  and
use some sort of RAID Software or buy a RAID Hardware Box like
a SparcStorage array.

What are the advantages and disadvantages of each approach. What
are the performance difference between the two RAID setups?

Thanks for the info.
