ESXi: mapping storage adapters to physical storage ports on the motherboard.

kuldipsingh — Fri, 13 Mar 2009 13:49:42 GMT

My ESXi host detected the following 6 storage adapters.

vmhba1,vmha33, vmha33 , vmha35, vmha36,vmha37

My motherboard has 6 SATA ports.

Could anyone confirm if the following mapping is correct?

vmhba1: SATA PORT 1

vmhba33: SATA PORT 2

vmha34: SATA PORT 3

vmhba35: SATA PORT 4

and so on.

However, I have hard time understanding the mapping when I look at my MB documentation. I think it is possible that MB manual may be wrong.

Motherboard (Asus P5Q PRO) manual has the following settings for SATA PORTS:

SATA 5 SATA4 SATA2

SATA6 SATA3 SATA1

ESXi: best practices to locate VMs among multiple hard disks

kuldipsingh — Fri, 13 Mar 2009 13:37:11 GMT

I need some suggestions on this topic.

I have 6 DATA Stores and each corresponds to a physical hard disk. I am planning to create quite a few VMs on my ESXi host. Most VMs will also have a virtual hard disk of its own to store data.

I have the following VM types:

VM01: Domain controller 01(win 2003)

VM02 : Domain controller 02 (Win 2008)

VM03: Domain controller 03 (Win 2003)

VM04: Exhange server 2007

VM05: File server 01 (WIn 2003)

VM06: File server 02 (Win 2008)

VM07:Security server (MS ISA 2006)

VM08: Firewall (pfsense 1.2)

Whats is the best practice to locate these VMs among the available datastores to get the best possible performance.

Hello,
Were you able to get your machine to run properly on ESXi with the described configuration? I'm about to buy a machine with a similar configuration, and I'd like to know.
Thanks

ESXi: Organizing VMs on a single host

Dave.Mishchenko — Tue, 28 Oct 2008 09:01:29 GMT

With the default settings on the resource pool, you won't have any resource limits in place but should VMs in all 3 resource pools being trying to access the same amount of memory / CPU resources, then each pool would have an equal share of the total resources of the host. Thus you might want to lower the shares (or place limits) for your dev / test resource pools. Once you have the pools created, you can just drag and drop VMs to them.

yes, is add to inventory. Register is the command we do use to register from SSH.

ESXi: Upgrading memory on host causes BSoD in windows VMs

Leafy911 — Thu, 23 Oct 2008 13:59:41 GMT

Glad I could be of help!

I have 2 ESXi servers at the moment, one with mixed memory DIMMS and I have not seen any issues as yet.

Anytime I do have issues with any system running any OS, I start by simplifying the situation by removing complications such as mixed memory, addition adaptor cards, device drivers etc. By using this method you should be able to isolate the issue.

ESxi: using existing virtual disk caused "A file was not found" error

kuldipsingh — Wed, 22 Oct 2008 15:57:48 GMT

Steps I have completed.

1) Delete the disk from VM that was linked to this virtual hard disk. I only deleted it from the VM not from the datastore.

2) Moved this virtual disk along with all the other required file as a complete package from one datastore to other.

3) Open the VM edit window and tried to add the disk. I selected use existing disk and browsed to the locations of the disk and follow all the steps.

When I click the last OK button, it gives me "A file was not found" error.

I know I files are there. I did not delete any time. I just moved them to a new location. Any idea?

ESXi: installing a new ssl certificate

kuldipsingh — Wed, 08 Oct 2008 13:47:49 GMT

I have a commercial certificate along with private key for my esxi server. I want to install this certificate on the esxi host. How to do it?

I have tried the following but no success.

My esxi host name is esxi.friendspc.ca and certificate has the exact same name.

1) Copied esxi.crt and esxi.key file to /etc/vmware/ssl and renamed the existing .cer and .key files.

2) Restart the services. However I was not able to login from VI client so obviously the certifcate was not installed properly.

Key points:

1) I am copying the certificate from windows system to esxi host using DATA STORE browser.

2) When i have a peak at the certifcate on esxi host using vi edito, I found some weird extra characters added to the end of each line. I guess this is the work of windows NotePad editor. However, I do have removed those extra characters using vi editor. Is it ok?

What am I doing wrong?

ESXi: moving to RAID from regular configuration.

weinstein5 — Tue, 30 Sep 2008 20:44:25 GMT

Answer 3 and 4 - Number of ways to do this - you can use tools like WinSCP, use the datastore browser

Answer 5 - really is going to depend on you RAID controller cards - most it will require a shut down and reboot to replace the disk -

Interesting and very interesting. Actually, it was my ethernet cable. I replaced it and now I am getting full speed.

ESXi: few general questions

weinstein5 — Mon, 15 Sep 2008 15:45:29 GMT

Not sure - this can be caused by many things - what else if running on the ESX hosts - how many VMs, etc
All depends on the loads being placed on the virtual machines and how many virtual processor each VM has - if your virtual machines are carrying a light load you can quite a few more running then loaded VMs - also having dual/quad virtual cpus will also limit the numebr of vms you can run - the one thing I will say about the specs 8 GB is a light amount of memory
With fours IMO I would create a RAID5 set that way you do get some resilience in case of drive failure
The network adapters will be identified but you will need to configure so they can be used - chekc out http://www.vmware.com/pdf/vi3_35/esx_3i_e/r35u2/vi3_35_25_u2_3i_server_config.pdf
