I am working thru designing a Citrix MF PS 3 farm. (with some other Techs) In the advanced concepts there is a table identifying the size of the data store (hd space). Space most likely will not be a problem but I want to work thru it anyways. One of the items is "add resource manager metric for one server (CMFPS/data store bytes written/sec) 1808B" QUESTION: is this a constant stream to the data store? Don't think so but not sure. ZDC??? if so then for an example is this what I would be looking at: monitoring 10 objects 18,080 bytes per second from each server back to the data store???? I have also been asked to look into IMA HW sizeing. Don't really know what that means? All the servers are using IMA Thanks _______________________________________________ Doug Stratton CITS Technology Development Analyst Work: 250-356-6678 doug.m.stratton@xxxxxxxxx <mailto:doug.m.stratton@xxxxxxxxx> _______________________________________________
