We have a over 100 SW users and we finally got the majority of them off of Dell 490s and WIn XP. The 490s were 7 years old.
Our IT is looking at every 5 to 6 years. What is you companies replenishment plan? How many users?
We don't have an established cycle, we replace and upgrade hardware based on need not on time. Some users scale positions faster than others and their hardware demands have a faster lifecycle. We also continuously increment the large/complexity of our CAD/Modeling environment so whenever we can justify upgrading someone, we do. Some upgrades take 3 years or more, some within a couple of moths. As Anna mentioned we don't dispose of hardware it usually just trickles down to other departments.
We are at 3'ish years. We will time the refresh to be at the beginning of a new Intel cpu release cycle. We do not buy computers at the end of an architecture cycle. If we need computers today we would be waiting for the new CPU architecture coming out this summer before making the switch.
We have 4-5 full time SolidWorks users. After 3 years the machines are cycled through our CNC and Wire operators. They use our SolidWorks models for their cutter paths. After that the computers go to low level tasks that do not need a high powered computer. Not uncommon for a computer to be around for 10 years as it gets moved down the food chain within the company.
We used to be on a 3 year cycle but stretched it out to about 4 years most recently. Typically the same process of moving machines down to folks who don't need the power.
We are on a 3 year cycle that has been stretched... and postponed... and delayed... All of our CAD workstations were built in 2005/2006. But they are shiney like a new penny compared to the server room. Thinking of renaming our servers to Nina, Pinta, and Santa Maria.
Thanks all for the responses!!!
The last company I was at was 3 but like others mentioned those could get delayed depeninding on funds and the economy. When I herad we are going to shoot for 5 to 6 years I became very concerned. It took a years+ of data supplied by SW that showed that the majority of the crashes that we were running into were memory related, XP 32-bit. Now that we are on Win7 64-bit with 12G of ram those types of crashes have just about disappeared.
I like Adrian's method of baseing it on need not time. If I can get our IT department to benchmark the computers befroe they roll them out and then rerunn the benches yearly I may have the justification needed.
Have you considered leasing? They don't do it here but at the last place they did. That way it's budgeted each month and you don't have to get approval/appropriation for new machines.
That is the way IT used to do it but for whatever reason went away from it.
