First off, let me describe the situation:
We've just received our new server:
- 32 gb ram
- 2x 100gb enterprise ssd's (which we'll put into raid1 for write cache)
- 8x 2TB SAS disks(raid 10)
- 2x 512GB ssd's (raid1, for the read cache)
- 4x gbit nic's
- running the latest version of freenas
What do we currently have
- 3x gigabit switches (storage1, storage2, internet.... 3x 2960s cisco switches)
- 4x ESXi hosts, with 3 nic's per server
We started to brainstorm on how to best connect the new storage unit to get the best possible performance.
First idea was to setup the freenas with: create 2x portgroups (LACP) of 2 nics per portgroup, but then somebody suggested a different approach, setup 4 different ip ranges, configure 2 vlan's per switch, connect 2 hosts into vlan 1+3, and the others to 2+4:
freenas nic1: 192.168.1.1, connected to switch A, vlan 1
freenas nic2: 192.168.2.1, connected to switch A, vlan 2
freenas nic3: 192.168.3.1, connected to switch B, vlan 3
freenas nic4: 192.168.4.1, connected to switch B, vlan 4
srv1, storagenic1, 192.168.1.11, connected to switch A, vlan 1
srv1, storagenic2, 192.168.3.11, connected to switch B, vlan 3
srv2, storagenic1, 192.168.1.12, connected to switch A, vlan 1
srv2, storagenic2, 192.168.3.12, connected to switch B, vlan 3
srv3, storagenic1, 192.168.2.13, connected to switch A, vlan 2
srv3, storagenic2, 192.168.4.13, connected to switch B, vlan 4
srv4, storagenic1, 192.168.2.14, connected to switch A, vlan 2
srv4, storagenic2, 192.168.4.14, connected to switch B, vlan 4
What do you think about such a setup, or would you choose a different approach?
