I'm using HP DL360p Gen8 for low latency trading (but not ultra-low-latency!). It means that i'm working in frame about "10+ microseconds" and i don't care about "1-5 microsecond" or nanoseconds.
I have dual Xeon E5-2640 and HP Ethernet 1Gb 4-port 331FLR Adapter. I colocate on stock exchange and connected using 100 MBit Ethernet cable.
I'm thinking what can be reasonable to upgrade and if it makes sense to upgrade this server or I should buy a new one once Xeon E5-2600 v2 is released. So I have following questions:
will it be possible to install Xeon E5-2600 v2 in this server? I'm thinking to replace two 2640 6 cores each with one top Xeon E5-2600 v2, 10 cores. I think one processor will be enough for me and I will avoid QPI link latency, DDIO will perform optionally etc. etc.
how much microseconds can I win replacing "HP Ethernet 1Gb 4-port 331FLR Adapter" with something else? I guess I should buy DDIO-compatible card, but what would be a good choice? Does it make sense to buy this expensive card (it seems it doesn't support DDIO btw)?
I'm under Windows yet but will migrate to Linux soon.
I'm not sure but probably my question is too localized and should not be asked on this site so. What would be a good place for such "localized" questions then?
