Rob, You are correct that firmware updates to the FSP are disruptive to the partitions - although I have been told, "Watch this space" for changes in that arena. But the HMC which is the point that facilitates resource movement, partition creation/deletion, etc can be updated, re-booted and generally maintained without affecting the partitions. One of the major reasons for having a skinny primary is so that no applications or production work occurs in it, providing less chance of a problem occuring that will bring down the partition and any secondaries. >From a cost perspective, I have to disagree with you. Our typical primary consisted of 1 RAID card - $7200 4 x 4319 dasd units - $3000 2 x 2838 LAN cards, 1 x network, 1 x LAN console - $800 I am already over 10K, and that is without factoring in the cost of a partial processor, half a GB of memory, some sort of tape card to back the thing up, plus I need to get another CD drive as the primary wants to keep the CD drive in the CEC all to itself. I also have to supply a PC to act as the console, along with a copy of Windows, plus Anti-virus software, plus, plus, plus. My HMC cost $3,800 for rack mount, or if I want to be cheap and get desktop, its only $1,800. Even with one i5, I still think it is a bargain. Note: All prices quoted are list prices :) Regards Pat.
