comment Router/Firewall Hardware Failure Testing
Since we're out of maintenance contract, and this product is EOS'ed -- I guess follow-up question would be then is 10 years of lifetime reasonable for an appliance firewall/router like this? Or should it last longer/shorter? On the edge of just pulling the trigger and getting something new (not sonicwall).

comment What are the possible issues in using very short DHCP lease time (< 1min)?
you could also just reset/drop all leases from the server after each demo...

comment RAID-5: Two disks failed simultaneously?
@Wardy RAID5 or RAID6 does not give the same performance as a RAID10, not even close. RAID5 and 6 get a read boost, but writes takes considerable longer. RAID10 has improved writes and reads. Depends on your expected i/o load. If you are running something write-intensive, such as a VM cluster, then you will benefit immensely from RAID10 in a 0 + 1 configuration. However, since the OP is considering a separate chassis, it's really a backup server with complete data set, so this point is moot.

you are talking about setting up rsync on the box-to-be-backed-up, and then switch to rsyncd in BackupPC so that box pushes it's data to the backup machine? Or are you saying I should bypass BackupPC alltogether and just rsync the data manually?

comment RAID-5: Two disks failed simultaneously?
@Wardy That is a lot of additional expense just to have a redundant (ie. mirrored) array. Just switch over to a RAID10, you will get much better write performance, plus you can loose half your disks and stay online (depending on which side of the mirrored raid 0's fail). Less cost, better performance.

@Zoredache hmm, one of the drives on the problem box has: 392,756 files, the other drive has: 615,490 files. So, ya... a lot of files! It did take a while for find . -type f | wc -l to run...

@Zoredache it's a mix. This box is used as a sort-of low-priority file share for some of the users... they tend to stuff it with a mixture of stuff, lots of directories and directories in directories, etc... filled with everything from excel files, word docs, access db's (varying in size), up to program installer exe's, iso images, etc. I would suppose there are more small files than large though. The small file issue was one of the reasons the internet recommended switching to tar, that it may help... is there a flag or something I should modify?

@MichaelKjörling I think you underestimate my beer-packing capabilities ;-P

This box will be hosting some virtual disk drives for the Xen cluster over iSCSI, but will also likely have a CIFS share on it for office file sharing. So, there will be a mix of large files that have constant moderate I/O and some mostly static files that get read more then written to.

@MikeyB Oh, I always pack it in there ;-) How else can I fit all that beer?

Yes, it's a fresh build with FreeNAS running on top with ZFS RAIDZ2. -- I just wanted to make sure I wasn't going to sound like a crazy when I tell management we need to buy a few extra hdd's just to have them sit empty all the time ;-P
