".. Rob, I thought the mantra was "disk is cheap". IBM disk has never been as cheap as PC's but that's been the "tax" you pay for the connivence, quality, and service of being "i"ntegrated. You have said before that you don't like off-brands for iSeries disk because they have more issues than true IBM drives. .." I'm with Rob. BTW, I don't think IBM even makes their drives anymore. I'm sure the DeskStar line has been sold to I think Hitachi, When I upgraded my 730 to my 810 and migrated my drives, I removed alot of hardware around the drives. That was probably all the 'special' hardware that made them expensive. Essentially looks like a PC server drive. I don't even think their Fibre Channel drives, standards SCSI. I'm dealing with the same problem Rob is. We three run Domino servers on our iSeries (Dvlp, Application, and Home Office email). One Windows Domino server in our DMZ to route mail to and from our internal servers. We ended up buying an EMC SAN because IBM disk were too expensive (Other Open System servers use the SAN). Now some compliance person says we have to keep a year of email... That's alot of email (currently use 45 GB for apprx. 20 days retention). So, hmm, where are we going to store hundreds of GB of email.. $2500/73GB 15K SCSI iSeries drive or $300/300GB 10K SCSI EMC drive (remember - long term retention). How are you going to back up your Linux server? There are backup solutions for Linux. I'm sure even IBM sells one. Still way under the cost of a drive. Now, If you had a SAN (read cheap disk) couldn't you create a Linux partition on the iSeries and mount that external file system. > TSM?Oops, the data is back on the iSeries! That's OK, though because disk is > cheap. If you start adding in the costs of a tape drive and tapes for your > Linux system you may be eating up some of your savings. You could put a 3581 (LTO) drive on a Fibre Channel switch and share the resource, I would think. Same tape and drive that you use for iSeries (assuming you've upgraded you tape technology). I think IBM is gouging us for disk.. simple. m.
