Also, perhaps you should elaborate on why you need something better than 15 minutes data loss. Perhaps the question you really want to ask is that aside from using backups, what alternatives are there towards speeding up a recovery of data in the event of failure. This MAX 15 minutes of data loss seems quite low in comparison to the rest of the sites I have been familiar with over my experience base. If this is true, I'm surprised that you are worrying so. The max of 15 minutes back on your backups seems very aggressive to me. You already have backups in place, so you seem to be covered there. In fact, one of the drives might be corrupt itself causing the server to die. I have found the simply moving a drive from one system to another is not necessarily successful for a variety of reasons. You assume that your server being down is not due to the SAS drives (highest probability of failure). Sort of a RAID 1 (mirror) where one part of the RAID is a local drive(s) and one part is on the network? They are often the same pysical cards as SAS RAID cards, but with a different firmware.ĭid you consider keeping a copy of all the data on the network. And if you are concerned about 15 minute delays then make sure you have such a card as a spare. This will just work, and this is something you can test. In most cases you can just get an identical or similar RAID card, plug in the drives and access the data. Other then buying a RAID controller and plugging it into a workstation (in which case I still may not be able to connect the drive while leaving the data intact as this is a RAID controller, not a simple HBA), what are my options? Other then buying a raid controller and plugging it into a workstation (in which case i still may not be able to connect the drive while leaving the data intact as this is a raid controller, not a simple HBA), what are my options?ĭoes something like a simple (non raid) PCIe HBA card that just lets you plug in an SAS drive exist? or better yet some sort of external enclosure? I can't find either on google. would be a major advantage, if i could only get to the data. Yes, we have a full backup solution with snapshots, offsite replicas etc., still the backup could be up to 15 minutes behind and in some cases i would need the backup server (which could be down) running to access the data from the backup sets anyway.īeing able to restore from the production drives, or at least access the data on them for recently changed files etc. I don't have another server to plug them into, and even then connecting the drive to a different controller (while keeping the data) is not a certain thing. If my server goes down, how can i access the data on the SAS drives?
