Blogging from the iPhone

I’ve had my iPhone for about a week now and I’m still exploring all the cool features (there’s an app for that). I was one of those folks that always figured my cell phone just needed to be a phone, and really that’s all mine ever was – until now. What an awesome piece of technology!

I can check my email, get my bank statement, listen to music, play games, track the ISS, and even blog! I am in fact writing this blog post on my iPhone.

So far I have been playing with some of the free apps (there a 100s of them) and I am pretty impressed with the quaility of the free apps. The wordpress app that I am using to post this allows me to post to all of my blogs and moderate the comments on each of them and it’s FREE!

Very cool!

I’ll post a bit more about some of my favorite apps in another post

Have a great weekend!

Staging Patches in vSphere vCenter Update Manager

New feature in vCenter Update Manager allows you to stage vSphere updates before installing them.

Use the Stage wizard to download the patches before using remediation. This downloads and prepares the patches while the host is still online. This decrease the amount of time the host is off line (in maintenance mode) will applying patches.

You can stage at the cluster and Data Center level to prepare all hosts in the cluster for remediation.

Shortcuts in Home-Inventory-Hosts and Clusters

Just updated to ESX 4.0.0 build 175625. Staging took about 3 1/2 minutes total and remediation took about 12 minutes per host (this include Entering maintenance mode, VM migration, patch installation, reboot, exit maintenance mode). Three and a half minutes of savings may not seem like much, and across three hosts it really isn’t that big of a deal, but across 20 hosts that would make a huge difference.

Awesome new vSphere feature!

vSphere vNetwork Distributed Switch vDS Configuration

One of the new features of vSphere is the vNetwork Distributed Switch (vDS). Basically vDS allows you to create, manage, and provision your virtual network across all of your vSphere hosts in vCenter. vDS is available under the Enterprise Plus license.

Here is how I set up my vDS. I basically used the 3 host configuration example in What’s New in VMware vSphere 4: Virtual Networking white paper as a guide.

First I created a new vNetwork Distributed Switch in Inventory->Networking.

I configured it for 8 dvUplink ports. Why 8? Well I have 8 NICs in each of my host, and I would like to be able to use and manage all eight of them across one vDS.

I added each of my host to the vDS but did not add any physical adapters yet.

After the new vDS is created I created my port groups. One port group for the Service Console, one for vmotion, and one for each of my production VLANs.

When creating these port groups I just used the defaults except for changing the VLANs where needed.

Now that I have my vDS set up, time to migrate the host networks to the new switch. In Inventory->Hosts and Clusters select the host Configuration tab then Networking and the Distributed Virtual Switch button.

First i migrated the Virtual Machine networks to the new vDS. I took one NIC out of the port channel on the physical switch and added that physical NICs to the vDS. I did this for each of my hosts.

Then I use the Migrate Virtual Machine Networking wizard to move all of my VMs from the vSwitch port groups to the new vDS.

After this is done I add the rest of the physical NICs associated with my VM network to the vDS and recreate the port channel on the physical switch.

Now on to the vmkernel ports. I used the Manage Virtual Adapters wizard to migrate my VMotion VMKernel adapter to the new vDS.

I then did the same to my service console. Before I started making changes to the Service Console I put the host in maintenance mode. I created a new service console with a new IP address on the same subnet on my management port group and made sure I had connectivitiy (OK I did not do this the first time, messed up and lost the Service Console connectivity to my host – had to go CLI to fix it, but that is a completely different multi-page post in itself – very thankful for the spare NIC I have in each host).

Since my vMotion vmkernel port and Service Console are now on the vDS I attached their physical NICs to the new vDS and then added them to the port channel on the physical switch.

The only issue I had was with the iSCSI vmkernel ports. I was not able to get them to work on the vDS so they are still configured on a vSwitch on each hosts.

Not sure why I could not get it to work, but I will tackle that another day.

After I verified everything works, I deleted the old Virtual Switches from each host.

Just a quick overview of how I set up my vDS. Hope you find it helpful.

TGIF!

HAVE A GREAT WEEKEND!!!

Vizioncore Puzzle Contest – I WON!

Check it out I was chosen as one of the winners in the Vizioncore Crossword Puzzle contest that has been going on the for the last few weeks! The contest was to promote the release Vizioncore’s backup product vRanger Pro DPP 4.0.

I guessed at the last clue and looks like I got it right.

Very Awesome!!!

Mozy Online Backups – Backup Your Home Computer

If you are looking for a way to backup your home computer check out Mozy.com. They offer a 2 Gig backup for free but for just $4.95 you get unlimited backup for a single computer. They have clients for Windows and Mac.

“Mozy is a simple and safe way to back up all the important stuff on your computer. A copy of your data is stored in a secure, remote location for safekeeping, so that in the event of disaster your data is still retrievable.”

Sign up for an account, install the client, select the files you want to backup, and that’s it. There are some tweaks to allow more bandwidth to be used for backups, or backup only when idle but I just selected all the defaults. The initial backup took about 10 days for 45GBs of data, but now my data is quickly backed up daily. I am sure they are using some sort of source de-duplication similar to AVAMAR.

Here is a capture from my Mozy account of my backup data

I have not tried to do a restore yet, but I have browsed through my backed up files on the Virtual Drive created when you install the Mozy Client and using the Web restore online.

If anyone from Mozy reads this… I wish you had a Linux Client!!!
