Hello, I have a newly built All-In-One. It is currently on ESXi v5.1 Update 1 with just one VM installed currently, OmniOS with napp-it. Server Specs: Intel E3-1230v2 32GB 1600 ECC UDIMM SuperMicro X9SCM-IIF 2x IBM M1015 (IT Mode) connected to 10x Toshiba 3TB in RAIDZ2 1x 16GB SanDisk Cruzer Fit USB Flash Drive (for ESXi) 1x Crucial M4 256GB SSD (for my VM's) Connected via CAT 5e on a Trendnet 16 port Gigabit switch Usage: I plan to just run 2 VM's on this system. Primary Vm, will be OmniOS for file server duties using ZFS. I also plan to use it for FTP and SABnzbd. Second VM will be pfSense which I hear is amazing. I will enable full pass-through of the 2 IBM M1015 to OmniOS. Based on my intended usage, what settings do you guys recommend? ESXi Related Questions: 1. How much RAM should I allocate to OmniOS? 2. How many vCore and vCPU should I set for OmniOS? 3. For best network performance, should I use vmxnet3 adapter or the E1000 virtual adapter? One guide I read says to use vmxnet3 while other says E1000. 4. Since the mobo has two Intel NIC's. Should I use use the other NIC and pass-through to PFsense? 5. Since my pass-through 2x IBM M1015 have the v16 BIOS. Should I load v16 drivers into ESXi or in the OmniOS VM? 6. Any other ESXi related settings/tweaks I should configure? napp-it Related Questions: 7. When creating a pool, ZFS version of pool, should I select the standard "default" option or is there a particular version I should use? This is the first time I will be using my 10x 3TB Toshibas, so I am not coming from a older pool version. 8. Any other particular tweaks I should perform in napp-it? I mainly followed the guide on napp-it.org. Look's like there is nothing else to really tweak besides creating the network shares, but figured I would ask. Appreciate any feedback!
