 SUN Fire 280 Performance Hi I've got a SUN Fire 280R with 2x72 gig FCAL drives 10k RPM, 2xSPARC III 1.2Ghz and 2gig of RAM, just recently I was loading a decent sized database using BerkeleyDB from sleepycat and noticed that performance was in no way stunning using the same database on a Compaq Proliant 1300R which has 1x500Mhz Pentium III , 512Meg of RAM and a RAID I noticed the performance was far better by an order of magnitude I assume the RAID is making some difference as it's got a 32meg cache but is there anything I can do to improve performance onthe 280R the performance difference made me wonder if the 280R is not configured correctly as I can't beleive the 280R can be slower Any help is appreciated Regards Paul Hirst, Software Engineer      |

If this is your bottleneck the only thing that will improve things is adding more disks. Right now your 280R is waiting very fast for data to get off or on disk. /wfr Fredrik -- Fredrik Lundholm dol @ ce.chalmers.se |

| Re: SUN Fire 280 Performance Hi Yeah I'd begun to figure it was disk bound as compile times are stunning on this box, last night I turned on the write-cache-enable in the format menu and this did seem to make a difference, would you recommend going for a RAID solution ? the reason I ask is were currently in the process of replacing all of the Compaq servers running Solaris 9 with SUN SPARC kit Many Thanks Paul Hirst, Software Engineer "Fredrik Lundholm" <dol@ce.chalmers.se> wrote in message news:bkv9sa$ovo$1@eol.dd.chalmers.se... > In article <fkp5nvsr05e5k64uqj6701m7e0n4beqdim@4ax.com>, > Paul Hirst <paul.hirst@codescape.co.uk> wrote: > >Hi > > > >I've got a SUN Fire 280R with 2x72 gig FCAL drives 10k RPM, 2xSPARC > > >I assume the RAID is making some difference as it's got a 32meg cache > > OK, each disk drive can probably sustain apx 10 IO-ops / second. > If this is your bottleneck the only thing that will improve things > is adding more disks. > > Right now your 280R is waiting very fast for data to get off or on disk. > > > /wfr > Fredrik > > > -- > Fredrik Lundholm > dol @ ce.chalmers.se > |
