Post HP ML110 G6 X3440
There are some misconceptions out there that workarounds are required for vSphere 4.1 to install successfully on this model, but that is not the case.

I had it only temporarily because I want a machine that maxes out at 16 GB RAM instead of 8 GB. However, while I had it, the ML110 G6 performed quite well, and it is a steal @ $583 at Amazon.

Here are my specs:

- server / MB / NIC / controller make and model
HP ML110 G6 X3440

- chipset
Intel 3240

- CPU socket and type used
Intel Xeon X3440 - Quad Core with HT

- BIOS / firmware versions
Stock that comes with the server. Sorry, i do not have it anymore

- are the onboard NIC / storage controller working
Yes

- any changes required to enable ESX/ESXi to recognize hardware components
None
NOTE: Some people reported needing to change storage controller settings in the BIOS or that the internal CD reader could not read the media properly. I did not have to change the BIOS.

The problems with the internal CD drive may be more due to the disk not being burned properly. Thus, when they change to a CD Writer or some other model that's "less finicky", the HP would have a better chance of reading the disc, which is what people used to workaround that problem.

I burned my ISO using Mac OS X's Disk Utility, and the HP's internal drive did not have a problem with it.

- does the storage controller support RAID / battery backup for write cache
Did not try

- does the MB support Intel VT (vt-x) / AMD-V
Yes

- does it support vt-d (directed I/O) / AMD IOMMU (http://en.wikipedia.org/wiki/X86_virtualization)
Did not try

- is the CPU FT (Fault Tolerant) capable - use the following bootable ISO image to check this
- http://downloads.vmware.com/d/details/c ... R0dGhidGR3
Did not try

Happy Testing, all! :D

These do support 16GB of RAM:

At one time I think the specs said 8GB but that wasn't true. 4 DIMM slots that support 4GB modules. Thinking of grabbing two or three of these for a home lab.

Thank you for that spec update sir!!! I wish HP had updated that sooner.

Now I know what I'll be getting myself for Christmas...a pair of G6's

The performance really is great with the X3440 CPU.

I hope they're still around by then.

Post Re: HP ML110 G6 X3440
Hi
Newbie Question - I work in IT on MS servers but I'm very new to ESXI, today (30-Oct-2010) for the very first time I installed ESXI 4.1 on my HP ML110 G6 Single SATA drive (non RAIDed) server. I am hoping someone can help me answer this question or if it's at all possible and what I will need to do if it is possible. My plan is to have test LAB of x2 HP ML110 G6 servers using single SATA HD running 3 MS OS's on each server, that will mirror each other over the network for fault tolerance, i.e if the physical HD in one of servers fails the other ML110 G6 will automatically kick in or take over so the users on the network will not notice that the other server has failed.

My Current Setup:
x2 HP ML110 G6 (Each Server Is Physically Identical)
x2 Server 2008 R2 x64 OS
x1 Server 2003 IIS Web Server x86 OS
x1 2.3Ghz Quad Core CPU
x4 2GB RAM = 8GB RAM Total
x4 250GB SATA HD (Non RAID)
x1 Freecom External USB DVD-ROM-RW drive
x1 BIOS Hard Drive Configuration set to ACHI
Couldn’t get ESXI to work when set to RAID

x1 Latest BIOS installed today (30-Oct-2010) with extended x64,
http://h20000.www2.hp.com/bizsupport/Te ... bfe42eadf9

Is it possible to mirror the live environment on a single SATA HD of one ESXI 4.1 server to another identical redundant server so if the primary server fails the second server automaticlly takes over and visa-versa.

Thanks in advanced

Trevor

VMware Fault Tolerance requires some form of shared storage and you need the proper licensing level for vCenter and ESXi.

You could look at a 3rd party tool that replicates servers like Double-Take.

Depends on your SLAs. If absolutely 0 downtime allowed, FT is the only way to go. Please keep in mind FT's requirements, though (ex: only 1 vCPU allowed, etc.)

If your SLAs allow seconds or minutes of downtime (ex: the user has to reopen Outlook if the Exhange server fails over), either VMware HA with DRS or a 3rd-party tool is sufficient, depending on your budget.

Thanks for the suggestions, As I’m a newbie double-take sounds good but I have nothing to compare it with or on costs, this is for my home DC failover but I may be able to recommend the tested setup for work, so either I need to buy it for myself and recommend it or obtain a full trail to test with then recommend it. I just need to ensure that if the primary server fails then the secondary server kicks in as a mirrored setup/configuration as the primary server.

What is FT?

What is VMware HA with DRS

Sorry for the silly questions.


Thanks
Trevor

Both Fault Tolerance (FT), High Availability (HA) and Ditributed Resource Scheduler (DRS) require some form of shared storage. With DRS VMs are moved between hosts depending on the load of the hosts. This can be configured in a fully automated mode in which your vCenter host determines how to balance your VM load and moves the VMs as required.

With HA, if a host fails the VMs are restarted on another host. This provides basic failover, but the guest OS is completely restarted (i.e. as if the power plug was pulled on a server).

With FT a single VM runs on 2 hosts. The copies of the VM keep in sync and if the primary host fails the backup copy of the VM takes over as if nothing happened.

Hello Trevor (great name by the way),

We are all here to learn, man. So, ask away

FT is the Fault Tolerance tech mentioned by Dave.Mishchenko in a previous post. You have two ESX servers running copies of the same VM in lockstep. Only one instance of the VM is ever active at any time. As a change is made to the live VM, the hot copy is immediately updated.

That way, if the VM ever goes down, the hot copy takes over immediately with no data loss. Great tech, but it has a stringent set of requirements. It is also part of the more expensive licensing options. So, unless your environment requires absolutely 0 downtime, you may want to consider other options.

HA is High Availability and DRS is Dynamic Resource Scheduling. High Availability will automatically bring up VMs on another ESX\ESXi host in the event of a failure on the original physical host that the VM was running on. DRS will automatically shift VMs between physical hosts depending on policies that you set (ex: move VM from Server A to Server B if Server A resource usage is high).

All of these solutions require shared storage.

3rd party solutions provide varying levels of protection without requiring shared storage including

1. HA of the entire ESX host (DoubleTake)
2. HA of the individual VMs (CA, DoubleTake, etc.)
3. HA of vCenter itself (CA, DoubleTake, etc.)

Since you are just starting out with VMware, you will find a lot of answers to your questions (even the ones you haven't thought of yet :-) ) on the VMware Communities Site (http://communities.vmware.com/home.jspa)

Happy VM'ing,

Post Re: HP ML110 G6 X3440
Thanks Dave, Trevor

I went through the links you provided and wow it's opened up a whole can of worms, “my head is spinning” but I think I have the overall principle. In a nut shell is this correct......

OK here goes:-

vSphere, is the overall software/server that allows me to monitor and configure multiple esxi servers for FT or HA with DRS using a 3rd party shared storage “i.e. 2 esxi server – 3rd pc holding the vm images/files which both server are looking at”.

vCenter, is the control panel that sits on the esxi server which allows me to add/remove virtual machines.

vPxclient is the app which connects to the vSpher/vCentre/running OS
Double-Take is 3rd party software that will copy vm images from one server’s hard drive to another server’s hard drive on a scheduled basis.

I’ve had a look round the net but can’t seem to find any prices on vSphere or Double-Take any idea’s how much these cost cus I like the sound of the FT shared storage option, just means I will have to get another ML110 G6 for the storage "what a shame" :-).

Thanks
Trevor
