ESX boot from SAN - design limitations

Posted on September 26th, 2007 in SAN, esx by Rich

While working with a SMB customer this week I came across an unexpected problem. The customer wants to boot all of his ESX servers from the SAN as well as the VC2 server and a handful of other physical servers. They have an IBM Bladecenter and ordered several new HS21 blades without hard drives. So, after spending a day with the storage admin and developing the best array, LUN, and host group design we started to build the solution. Turns out that the customer’s SAN controller is a DS4300 turbo and is limited to a max of 8 partitions. (IBM calls host groups partitions for some reason.)

Considerations for Implementing Fail Over VI at a Secondary Site

Posted on September 18th, 2007 in availability, dr, esx, fail over, services, treesum, vcb by Rich

These are my notes I used to prepare for a discussion with a client about implementing a secondary site for DR fail over. The client has already virtualized their production data center and is wanting to leverage VI for DR. The point of my discussion is that VI is too often viewed as a “silver bullet” for tough projects like back up and fail over. Yes, there are some specific areas that are easier to implement with VI, but careful consideration and planning must be executed if the overall DR plan is to be successful.

Goals and Objectives - the customer must make important decisions first !

 

· Recovery Time Objectives – acceptable time to start up systems and allow user access

requires server by server analysis

· Recovery Point Objectives – acceptable point in time recovery or start up at secondary site

requires application by application analysis

· Mission Critical Services

which applications & services must be available first.

Thursday 9.13.07 Keynote - what I missed :(

Posted on September 15th, 2007 in appliance, availability, gen session, stor vmotion, vmware, vmworld by Rich

Unfortunately I slept late Thursday morning. Waking up at 7:30 am in Hayward, CA meant that there was no way short of a helicopter I was going to make it to San Francisco before 9. I’m pretty sure my company would not let me expense a helicopter so I decided to catch up on some email from the hotel until traffic burned off. I also had “Smash Head” from the party Weds night!

blog.scottlowe.org has some great notes on this session. Here’s my thoughts on what I missed.

It’s a rental

Posted on September 14th, 2007 in vmworld by Rich

Chevy HRI rented a Chevrolet HHR for week at VMWorld. I wasn’t expecting to rent a car at all so thank goodness National had cars available Sunday when I arrived at SFO.

The car was fun to drive and it had a lot of pep for a 4 cylinder engine. Although I never had more than three adults in the car, the HR had plenty of room for passengers.

It’s compact design was both a positive and a negative. I was thankful for the ability to maneuver easily in downtown traffic and park in tight spaces, but the cockpit area was cramped. I kept rubbing my leg on the center console just using the accelerator. The windshield was small and very close, and my field of view was at roof level inside the car. I felt like I had to bend down to see.

The Rock (and Roll)

Posted on September 14th, 2007 in conf info, vmworld by Rich

Smash Mouth Rocks Treasure IslandIf Alcatraz is called “The Rock” then Treasure Island was “The Roll” for Wednesday’s VMWorld 2007 party.

First on stage was the Wonderbread 5. I believe this band was once a Jackson 5 tribute band that has now evolved into 5 white guys wearing afros that definitely know how to start the party!

Associatedentertainment.com describes this local San Francisco band best:

“With their tongue planted firmly in cheek, the Wonder Bread 5 posse fuses hip-hop, country-fied white-trash anthems, disco and hair metal, resulting in a high energy spectacle of fun, grooves and all the songs you love to sing…and sing loudly.”

Smash Mouth topped the evening off with all of their hits as well as some amazing Van Halen covers! The band started a multi song encore with a version of “Running with the Devil” that would have made even David Lee Roth jealous!

According to their web site Smash Mouth has a new album in stores and is also currently working on songs for an upcoming movie soundtrack. I will definitely be adding their newest CD to my collection.

Replicate your VMFS partitions - NetApp

Posted on September 13th, 2007 in SAN, netapp, replication, sol exchange, storage, vmworld by Rich

Another “ton of bricks” moment happened to me when I was talking about SAN replication with NetApp yesterday in the Solutions Exchange. Using your WAN, NetApp’s products can replicate block level data between each other, or they can replicate the data from your existing SAN.

So, this means that I can buy a single NetApp product and put it at my DR site and start replicating my VI for fail-over. I don’t even need to worry about building the ESX infrastructure right away. Although, the ability to test my DR fail-over requires I have ESX servers at my secondary site.

I asked for general pricing for a small office SAN. I guestimated about 3TB of data would be needed. Although they wouldn’t give me a firm quote I was told pricing should be somewhere in the $10k - $15K range.


Platespin PowerRecon Virtual Infrastruture Edition

Posted on September 13th, 2007 in P2V, capacity analysis, feature comparison, platespin, powerrecon, services, sol exchange, vmworld by Rich

I received an email announcing a new release of PowerRecon from Platespin. It sounds like features have been added to the product to take it from being a capacity analysis tool to a VI monitoring and reporting tool. I will have to stop by their booth and get the scoop.

From the email:

PlateSpin is announcing the general availability of PowerRecon 3.1., and the new Virtual Infrastructure Edition.

Highlights of this release:

VIE features:- Integration with VMware Virtual Center

- Discovery and inventory of the complete physical and virtual infrastructure

- Power and Cooling Reporting

- Virtual Infrastructure Chargeback Reporting

- Virtual Machine Sprawl Reporting

- Priced per CPU

Other noteworthy feature enhancements:- Group and matrix reporting capabilities

- Scalability enhancements

- Tighter integration with the virtual infrastructure layer

- Extended platform support

Live VM backups from a VM - esXpress VBA

Posted on September 12th, 2007 in appliance, dr, esxpress, sol exchange, vmworld by Rich

You don’t have the budget for the required infrastructure of VCB backups? Try esXpress from PHD technologies. I mean literally, try their free 30 day, fully functioning, fully supported demo that can back up live VMs to a dedicated VMFS partition, an FTP server, or both! After the 30 days you can continue to perform daily full backups for FREE!

Once you install it on all your ESX hosts, you can configure the backups from a basic console GUI or integrated within the VI client connected to the VC2 server.

Vizioncore’s new products and releases

Posted on September 12th, 2007 in sol exchange, virtual iron, vizioncore, vmworld by Rich

Quest is the parent company of Vizioncore. Look for some new VI monitoring tools from these guys soon, but for now check out:

vRanger (formerly ESXRanger) - is still the best VCB based solution for live VM backups IMHO. I am not sure of the general availability date, but the product will soon use MS VSS as well.

vReplicator (formerly ESXReplicator) - Service console based VM replication. The only solution that I know of at this time that goes the extra step and registers the replicated VM in the VI at the DR site.

vCharter - monitoring, drill down performance analytics, and charge back reporting tool

vMigrator -

“vMigrator provides a powerful tool that can support the upgrade process from ESX Server to VI3, by enabling smooth and seamless migrations to the new platform with minimal downtime even for complex environments.”

vOptimizer -

“vOptimizer is an advanced optimization solution that quickly and easily reduces a virtual machine’s virtual hard drive to the smallest size possible while optimizing Windows guest operating systems for speed and performance. “

vConverter - similar to VMware’s VMConverter in design but can also V2V

“vConverter enables fast and easy conversions without disrupting the source physical system during the conversion process. There are never any reboots, no need to visit machines being converted, no software to install on the source and no downtime. vConverter contains advanced disk and network I/O algorithms to ensure that the fastest possible conversions are executed, and extremely reliable block level cloning is performed to minimize any risk of data loss. “

vPackager - sounds like this product will give some competition to VMware’s LabManager

“With vPackager, customers can configure a Windows based VM with the applications and configurations they wish to distribute, then extract these changes to a compressed package. This package can be distributed without OS licensing implications and applied to similar VMs to merge the changes.”

LeftHand Networks VSA

Posted on September 12th, 2007 in SAN, appliance, iSCSI, lefthand, sol exchange, vmworld, vsa by Rich

Virtual SAN Appliance for VMware ESX

I’ve been hearing about it all week. The President of my company sent me an email about this at the start of the conference. I finally got to talk to the LeftHand team at their booth today about their new virtual appliance - VSA.

You can download a trial version of VSA here.

Some notes about implementing VSA:

  1. you must reserve 1 GB ram for VSA on each ESX host
  2. you must reserve 2 GHz cpu for VSA on each ESX host
  3. you must create a dedicated Gigabit virtual switch for VSA on each ESX host

After you configure the VSA VMs on each of your local ESX VMFS they are clustered and data is “striped” between all hosts. Then if one host goes down the data is still available to the VMs as they are VMotion-ed or restarted via HA on the other hosts.

The VSA has native ability to do SAN based replication via the WAN.
