Using BerkeleyDB via 1GB LAN and RAID5
|
|
|
Hello,
we are planning to buy new hardware and consider to separate the
computing and storage. This would mean:
Box A: Much RAM and CPU where BerkeleyDB shall roam
Box B: Raid-Server connected to A via 1GB LAN
The documentation suggests not to do this, does this also account for
fast lans?
I've read that Raid 5 Systems have poor write performance but do well
on reading. Does anyone have experience with on or the other (or both)
that is: Separate storage via LAN and/or using RAID5 instead of RAID1
or RAID0?
Best regards,
Peter |

I think that speed is less an issue than correctness of remote
file access vs. local file access. How is BDB on Box A going to
access the data on Box B? When a write on Box A appears to
complete, will it really be committed to disk on Box B???
best regards
