Ideal setup QNAP and ESX

Hi

I am trying to figure out an ideal setup for an ESX environment running on a QNAP NAS to get optimal iSCSI throughput and redundancy.

I was thinking of the following setup.

QNAP with 4 x 1gbit and 2 x 10gbit ethernet
2 x ESX host with 4 x 1gbit and 1 x 10gbit ethernet
2 x 24 port switch (1gbit)

1. Attach ESX host directly to NAS on the 10gbe interface. This interface is reserved for iSCSI communication. If possible I want to avoid buying 2 10gbit switches.
2. Attach ESX 1gbit interfaces to the two switches. Two on each swtich
3. Attach NAS 1gbit interfaces to the two switches. Two on each switch

On ESX I define the 1gbit interfaces as failover iscsi communication in case the 10gbit link goes down.

 Architecture overview
Is such a setup feasible? Could I increase throughput through LACP on the 1gbit interface? How would I need to configure them?

LACP is not supported in ESXi in Standard Switches.

Using iSCSI you usually multi path the iSCSI traffic to increase throughout and also increase redundancy.

see my EE Articles, step by step instructions with screenshots.

HOW TO: Add an iSCSI Software Adaptor and Create an iSCSI Multipath Network in VMware vSphere Hypervisor ESXi 5.0

also enable jumbo frames

HOW TO: Enable Jumbo Frames on a VMware vSphere Hypervisor (ESXi 5.0) host server using the VMware vSphere Client

These articles are valid for ESXi 6.0 as well.

Also check your QNAP NAS is suitable for use with VMware ESXi, e.g. it's on the HCL.

Check the VMware Hardware Compatability Lists HCL here

The VMware Hardware Compatibility List is the detailed lists showing actual vendor devices that are either physically tested or are similar to the devices tested by VMware or VMware partners. Items on the list are tested with VMware products and are known to operate correctly.Devices which are not on the list may function, but will not be supported by VMware.

You may also want to consider and test the use of NFS.

Hi Andrew

Thanks for your answer

Yes QNAP is supported for VMWare ESX. Also supports VAAI

Multipathing over 10gbit ethernet would mean I need 4 links on the QNAP and 2 on each server I guess?
Or can multipathing be done through a mixture? 10gbit and 1gbit link? Is it wise to do that?

You would need at least two network interfaces on the hosts.

and for redundancy at least two on the NAS/SAN QNAP.

it can use 1GB and 10GB, but it's not often mixed.

Hi UNIX 86,

What's your QNAP NAS model ?

I'm using QNAP TVS-471 running QTS 4.2.1
