Example cost: Virtual Private Cloud (updated)
Feb 10th
Back in September, 2009, I had written a post with a quick overview of what a private cloud (or infrastructure) looks like and some basic costs and information, including why it is a great product (I am biased).
Since then, Dell has retired the PE2900III model server and items change, this is an update for the basic configuration.
Reminder graphic:
2 Servers, 1 firewall
So, originally, the physical servers were configured as:
- Dell PE2900III (reasonably priced, very reliable, I have spares on the shelf)
- 4 ethernet ports (2 built in, 2 port card installed, more can be added)
- 2 73GB SAS drives mirrored together for booting VMware vSphere 4
- 32GB RAM (48GB is max for this hardware platform)
New servers look like:
- Dell PET610 (reasonable price, very reliable, spares to go onto the shelf)
- 4 ethernet ports (all built in)
- 2 80GB SATA drives mirrored together for booting VMware vSphere 4
- 48GB RAM (192GB max available – very expensive)
The reason for the RAM change is that I am seeing a 2:1 (or higher) ratio of RAM to CPU usage in terms of percentage, and 48GB is a good place for this sized system. Also, the newer Xeon 55xx series processors uses RAM sticks in 3s instead of 2 or 4 at a time. 48GB is 12 4GB sticks of RAM. The newer 55xx series of processors also has working hyper-threading (or H/T) and I am seeing very nice performance on servers deployed using this processor family in our network.
Cost difference? The original posting listed had estimated the cost at $1,600.00 per month (see previous post), and I estimate this to be very close, inching up to approximately $1,700.00 per month, and this number should be high. (for accurate pricing, please contact ipHouse sales people, they can run up a quote based on real numbers)
VMware releases vSphere 4.0 Update 1
Nov 20th
The crowd cheers!
Though that might just be me :)
I am very excited for this update and I hope that it goes as smoothly as other updates have gone.
I have already updated 2 non-production systems (both ESX) and I am in the process of updating some non-production ESXi servers.
One of the items I need to schedule is the update of the vCenter software – this will require an actual outage for customers who are managing their VMs through ipHouse.
I hope that this update fixes 2 problems I have seen in the past (from the vSphere Client point of view):
- Inability for a datacenter administrator to view or clear host alerts and alarms from the hardware
- Interesting permissions issues that end up being more restrictive than the topic states
Both of these have been difficult to work around.
The first one requires the customer to contact us to ‘reset’ their hardware sensors.
The second one has actually hampered one customer from controlling their VMware cluster because of issues dealing with datastore management and the ability to attach an ISO image to their newly created VMs.
One item that is really exciting is the raising of the number of vCPUs (virtual CPUs) per physical CPU core to 25 per. Since we are able to sell VMware based virtual servers to customers, the ability to scale this higher could mean higher savings long term. Be nice to update pricing to reflect these savings later as well, though don’t know if there will be enough right now. At this point we really aren’t reaching the previous limit of 20 vCPU per pCPU.
Added support for Microsoft Windows Server 2008R2 is also welcome as we were wanting to deploy this version of Windows for customers.
Full release notes can be found here and are worth reading if you are into the enterprise products from VMware.

Example cost: Virtual Private Cloud on VMware
Sep 4th
In the last 6 months, I have helped multiple customers achieve their dream of a virtual machine environment built for them exclusively, but with abilities to control their virtual machine setup, configuration, turn up, tear down, etc. These dedicated infrastructure environments are in the ipHouse data center.
This isn’t ‘cloud computing’ as many people think of it (thanks to Amazon EC2 and the like), but it is pretty close to that vague definition, and with far more control available in terms of everything-vm-wise.
What do I mean? With this virtual private cloud, a customer can set up 3 Ubuntu systems, 2 Windows Server 2003, 1 FreeBSD, and 7 Windows Server 2008 systems. There really isn’t anything novel about this (again, reference Amazon EC2 and the like).
What is novel is that the customer can configure these VMs as they wish. Disk space allocation, partitioning, memory configurations, number of vCPUs. Basically, if you can do it on a physical server – you can do it virtually.
Another differentiating feature is that VMware vSphere 4 supports many operating systems while most public cloud providers offer a very limited number in comparison. This choice alone can be enough to warrant looking at this kind of solution.
No per hour fees, no storage fees (above what the customer has purchased), highly available (if configured to do so), dynamic resource scheduling (if configured to do so), bandwidth fees that are predictable. (see VMare vMotion and Storage vMotion, VMware HA, VMware DRS via website)
I’ll build a configuration example offering shared storage between the VMware physical servers. I’ll be doing some cost estimates for the per month fees. These estimates will be high and are purely shown for example. You would want to contact ipHouse Sales to get a real idea for the costs involved.
VMware vSphere takes me by storm
May 26th
Official download was available on May 21st, 2009, and I was waiting anxiously for my license keys for the new vCenter (management console) and host license keys (that which is the hypervisor)…
I got them on that day, and then proceeded to spend way too much time with it. For some people, addiction is a bad thing. For me…no need to guess.
I find playing and working with VMware (and the suite of tools available) to be on par with playing World of Warcraft. I can lose myself for hours and hours. With WoW, I complete quests, work with groups of people (9 or 24 others) accomplishing a goal. With VMware, I make clusters, I play virtual networking games, I make one computer act like many.
Since Thursday, I have upgraded my not-for-resale copies of vCenter and installed an Enterprise level host (well, upgraded from ESX 3.5 to vSphere 4 Enterprise). I want to get used to things. It hasn’t taken very long to get comfortable. Sure, some things have changed, but the core methods have not.
Hopefully over the next 2-4 weeks I can upgrade our VMware cluster(s) to vSphere 4 from ESX 3.5. The added performance benefits (according to VMware), the prettier and better organized client software (still no native Mac client, BOO!), and the eventual vNetwork Distributed Switch implementation.
My testing so far (ha, hard to believe what you can do in 4 days), upgrading the infrastructure shouldn’t be hard at all, and should be pretty seamless in our data center, though before the clusters get some love, I’ll be doing a few more test installs and test upgrades.
Until next time… VMware addict out!
