Okay, my curiosity is peeked. We have DMX box (EMC) so for our process for production packs/DR packs we need a total of 3 volumes. So I have my prod pack, my Replicate pack and a SNAP (Using FDR Instance).
How does IBM or HDS differ from that. Which uses less dasd and how is that done? I have just been assigned storage management duties and would like to understand different storage configurations and how each compares to the other. Thanks Lizette <--- Snip We have used the SnapShot process on a STK V2X ( eariler model ) and we have used FlashCopy on a HDS9980V. We have not experienced any subsystem performance issues with either subsystem. The issue we did encounter was trying to explain to management why we needed 'more DASD' on the HDS9980V vs. the STK V2X. As you may know, the answer is the way the STK V2X 'stores' data, especially as a result of the SnapShot process versus the way IBM, EMC & HDS 'stores' data. I think STK calls it: Log Structured Array. To me, its description sounded like 'virtual DASD'. Maybe 'virtual' anything wasn't cool 10 years ago when STK designed the Iceberg box. <--- UnSnip ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
