Interesting. We have two 3494 libraries - both with the HA feature. We've had several instances where hardware problems have caused a full outage on a lib. I'm not sure the HA feature is worth the price given how few actual problem there are and that the HA has failed. We also have two 3584 libraries (did NOT purchase HA). >From a hardware perspective I like the 3584 much better. It has fancy features, but at heart it's a standard scsi jukebox. I really like how fast it is. It's setup is easy, microcode upgrades are easy, fast (Hmm, I think I said that). The one problem we've had is that every once in a while TSM seems to get out of sync with it and we need to run a inventory (audit lib). My big complaint with it is that there is no good way to get information about the lib from our TSM server. mtlib will return a couple pieces of info, but not nearly what it gets from a 3494. Specifically, I wish it returned cleaning cartridge info and status info (there should be status info available about anything that causes a dial home events). Our 3494's are much slower and more complicated. We are planning a datacenter move. We need to move both a 3494 and a 3584. In talking with IBM - the 3494 is much more complicated for them to disassemble/assemble than the 3584. As has been been mentioned in other emails - it has the catagory stuff you have to deal with. In all the years we've had them, I can't think of a time where we ever had to do an inventory (audit lib). My personal preference - I'll take the 3584 based on it being faster and simpler, but both are fine libraries.
