One of the tasks I often get involved in is system sizing and capacity planning for GIS systems. The key reference for this is the excellent System Sizing Document produced twice a year by Dave and his Group at ESRI. The Paper is pretty long and can be kind of daunting when you first see it, however understanding it all is vital if you are going to be undertaking any detailed sizing tasks.

I had been planning on putting together a Post about which were the key bits of the document to look at if you wanted to do a rough sizing effort. So i just had a look back at the document and noticed that it has been updated with an October 2006 edition. There have been some pretty fundamental changes, to bring it in line with some of the new tools that are being developed to help the process and make it more up to date.

The Key chapters 7 and 8 have been completely re-written and updated. With the Release of 9.2 the new document has been updated with details of the sizing and performance as well as licensing mechanisms and recommended configurations. A new hardware baseline has been included and it also takes account of multicore hardware. The ArcGIS Server sections are much more comprehensive than in the last document, and i suspect there is still a bit more to come to help with some of the more complex aspects of 9.2 sizing issues. All I have to do now is find the time to digest the whole document, maybe on the flight back from Barcelona tomorrow.
