RE: ISCSI Boot Questions

You can either have just 1 card that you will need to remove from the machine with the hardware problem and place into another server or in our case we just got 2 cards and we can configure 2 separate machines to boot off the same lun. You just need to make sure that they are not trying to do it at the same time. Only one machine should be up on one lun at a time.

We are testing the Qlogic 4004 card and it works well. It's pretty easy to setup. You have it point to a lun and then boot off a CD and install Windows on that new iSCSI drive. I personally think it's a great way to get much higer availability without the added complexities of a full cluster. We have spare servers standby. With iSCSI booting, if we run into hardware problem, the operator can shutdown the server, boot another one in place and be up and running in less than 5 minutes.

What card is the most supported/liked for booting a diskless workstation via iSCSI these days? And second, how would you go about migrating a disk booting PC, to an iSCSI booting one? Ciao!

best backup for netapps
by Constantin Bogomolnyi 17 May '05

17 May '05

Hello, I'm wondering what is the best backup system for saving big netapps we have tried alot of solutions , but we finished by running 3 sets of netapp in snapmirror so A(master) replicates to B and C (slaves) all have now raid_dp enabled and spare around . So we have realtime B and C backups (we may cluster A and B) . But as its quite expensive "backup" i'm looking for some classic backup with tapes for example but i know from the past that tapes can be big pain to manage (specialy as we have around 2.5T of data on A) Anybody have some "tape backup" that realy works ? sub question : anybody have tried to attach a cheap ide raid shelf to scsi port of the netapp and use it as backup ? today its cheap to have 14x300 gig ide disk array with scsi port , so it could be better than tapes if its directly attached to the netapp , nan ? Best regards cb

Probably the best question is what exactly do you want these backups for? To be able to restore files people mistakenly delete/corrupt? For full-on disaster recovery? For long-term archiving? I think for the first one, various online or near-offline solutions like you've mentioned (ndmp to another server, etc) are probably fine, but then you could probably do just as well by just relying on snapshots and keep it simple. My personal opinion, which others might disagree with, is that for disaster recovery and *especially* for long-term archiving, you really need good offline storage like tapes. Something you can have shipped to a storage facility buried in a mountain somewhere. With enough money you could have multiple netapps around the country/world with snapmirror or somesuch replicating between them, which is great for DR too, but in the end I'm just not comfortable without something offline to fall back on. Imo the best solution is good backup software and a large automated tape library, but it's not going to be cheap. Even just the tapes can be a huge expense. We're still doing backups over NFS here, largely because when we tried doing NDMP a few years ago it just did not seem ready for prime time, we had too many problems. I'm very much interested in trying NDMP again though, as backing up over NFS is not the most efficient solution. I admit though, I've been in this business a long time and I'm a bit old-fashioned. Other people might be more comfortable than I am with relying entirely on hard drives for disaster recovery. -- Michael W.
