comment HP DL360p Gen8 for low latency trading - what to upgrade?
i want to update status of my project. I completely moved to C++ from C# and now have dual-boot system Windows Server 2008 R2 / RHEL 7. Still Windows in production, but i'm testing Linux. I installed "Solarflare SFN7122F" network card and it seems now networking is much better. Once moved To Linux I can also use OpenOnload. Then I will probably replace my server to HP DL360p Gen9 (i can keep using old HDD's and network card). After these steps I must be using one of the fastest server/network card/OS so I hope to be competitive

comment how to choose right SFP 1000BASE-T transceiver?
solarflare supported SFP's are here solarflare.com/Transceivers-and-Cables but I don't understand if they supposed to be connected to network card directly, or they can be connected to switches only? and what to connect to network card, then?

comment Can HP Intelligent Provisioning install RHEL using non-HP media?
i've found that at least on my HP DL360p Gen8 it's easier to use regular OS installer, probably on Gen9 server IP is better.

comment Can HP Intelligent Provisioning install RHEL using non-HP media?
@Gene I was calling our local Russia HP representative yesterday asking simple question "What is the correct way to buy self support RHEL for Proliant" and they answered me "I don't know, we more about hardware.". Probably I should try to submit a ticket because my server still has warranty.

comment how to choose right SFP 1000BASE-T transceiver?
i need 10Gb card to use OpenOnload or VMA for better latency. But I can't use 10 Gbit network because my stock exchange ask a lot of $$$ for 10Gb, but 1 Gb is much more cheaper

i've used Intelligent Provisioning to install Windows and everything was very good, all HP tools were installed, I like this.

comment Can HP Intelligent Provisioning install RHEL using non-HP media?
But I want to use Intelligent Provisioning because it makes things simple! for example "Ability to download drivers, firmware, and systems software by connecting directly to HP.com and to perform updates and install an OS in the same step"

comment how to choose right SFP 1000BASE-T transceiver?
do you know which one is better to use with HP 570SFP+ ? why different hardware require different modules? why they have different price? i don't understand that. for example I can use Ethernet cable to connect any ethernet devices, i don't need better, more expanive cable to connect more expensive PC.

HP-branded is MUCH more expensive than original Solarflare version, why should I pay for this? Which exact transiver should I buy to connect to 1 Gb Ethernet? Thanks!

comment HP DL360 vs DL160 Gen9
DL160 is not in the list of "recommended hardware". It would be interesting to know what exactly do I loose. I don't need many feautres, for example 16 GB of memory is enough for me, probably it doesn't make sense to pay for 360p Gen9.

comment HP DL360 vs DL160 Gen9
i think i can live with one E5-2660v3, but Solarflare or Mellanox network cards are mandatory.
