Who rips the $1,000 processors and $200 voltage control modules out of their servers to upgrade to $2,000 processors and $250 voltage control modules, then re-plans their entire infrastructure and possibly code back around that?
Symmetry between servers has a value.
The main board, raid controller, network, and usually the storage is going to be planned out meticulously ahead of time based on the maximum load the server is going to see during it's lifetime. Often, Processor and Memory come down to "If we needed X Feature and we didn't have it" or "If we took the server down for 1 hour to upgrade it, how expensive is that?".
- shermanyo 10y agoI misunderstood, sorry. I was talking in the context of virtual servers that can scale resources somewhat dynamically. (side note, isn't it awesome we see numbers like "512GB RAM" and don't immediately assume its not a single node in a deployment?) I initially pictured someone picking the highest spec option they can afford when setting up a new service, rather than choosing based on actual demand of each node. > "If we took the server down for 1 hour to upgrade it, how expensive is that?" Putting my CI / DevOps hat on for a sec: who takes production servers down for upgrades without some level of HA to avoid downtime? ;)
