Want to know more about the Cisco Nexus 1000V?

The Cisco Nexus 1000V is the first switch that can be placed in your vSphere virtual infrastructure, giving back network control back to the people that know the most about networking: The network admins. The Nexus 1000V is built on the distributed vSwitch technology in vSphere and can be managed by the same tools that network admins already use for manging their physical switches.

Cisco is organizing a series of free seminars aimed at sales professionals as well as admins.

The workplace in 2020

Have you ever wondered what the world of work would look like in 2020? I have. With the huge technological progress, it’s hard to imagine what we will be doing and how the world around will look.

If you look at the way we do our jobs today, it seems to be a lot like factory, blue collar labour. It is somewhat cleaner, but the way we do our work today is just like in the early 1900’s in the Ford factory at the treadmill. The industrial revolution made it possible to automate almost everything with machines. Only the parts that could not be automated, were filled by people. Still we treat them as if they are just a mechanical part of a larger machine.

Apple iPad announced, can it change daily operations?

Apple finally annoumced their tablet officially,dubbed the  iPad. The last months more and more rumors appeared on the internet. You probably wonder why this is interesting for the virtualization community.

Although a lot of people over at Gizmodo complain that it’s just an iPhone on steroids. I can see some real world applications for it.

Since I’m a real gadgetfreak, together with a lot of you I guess, I wonder how I could use the iPad in the daily operation. I see visions how the daily operation would look like.

vSphere 4: 9 months later

May 21th VMware released their new flagship product VMware vSphere 4 which should bring us tons of new features and performance improvements.

But how is the vSphere experience almost 9 months later?

Starting with the installation and setup experience, my personal experience with vSphere is very good. During the installation and setup of VMware ESX or ESXi 3.x I experienced a lot of issues like BIOS settings causing HA issues, HA issues when changing the ESX IP addresses, Problems with VMware Update Manager and faulty HP USB sticks. We even created a HA checklist for you to easily address HA issues.

Once up and running ESX(i) 3.x ran fine with the occasional HA error which 99% of the time could be fixed by reconfiguring HA from Virtual Center.

Now with vSphere the installation and setup is simple, error free and straight forward. Setup HA in the cluster properties wait for all progress indicators to reach 100% and you’re done.

Please tell me: ‘What is MED-V?’

This week I got the question if I could draw up a short lists of pro’s and cons for MED-V. Since I’m doing virtualization in the widest possible way, this fits well in my job description.

But heck, what a question! Before I could even try to  answer the question I really had to dive into the Microsoft Enterprise Desktop Virtualization solution (hence MED-V) which is part of the Microsoft Desktop Optimization Pack (MDOP). Sure, I already seen some comments on the internet about MED-V and I already was somewhat biased. Still I tried to make it an objective report.

Let’s start with what it is not in my opinion. Although it enables management of virtualized desktops it is not a full blown desktop virtualization solution like XenDesktop and VMware View.

VMware to acquire Zimbra

It was a rumor for some time but 45 minutes ago Steve Herrod, CTO of VMware, acknowledged that VMware has entered into a definitive agreement to acquire Zimbra from Yahoo.



First of all, for those of you that don’t know, Zimbra delivers open-source email, calendaring, and collaboration software for deployment within companies of all sizes, as well as to cloud and hosting providers offering mail services over the web.  From a business perspective, Zimbra is one of the most popular collaboration software offerings, with more than 55,000,000 users and a subscriber base that is growing rapidly.

So, why does VMware buy their own e-mail. calendering and collaboration platform? This has nothing to do with virtualization, right?

According to Steve Herrod there are two main reasons for the acquisition:

  1. Zimbra will further VMware’s mission of simplifying IT.

    VMware’s mission is to simplify IT, and every VMware product focuses on attacking the complexity and rigidity that has crept into this world. In many ways we see the excitement over cloud computing to be a longing for a simpler, more flexible way of doing computing. The VMware strategy is to help customers achieve cloud-like efficiency and operational improvements across the major IT infrastructure investment areas.

  2. Zimbra will add to the portfolio of offerings VMware provides to the VMware vCloud partner.

    This second motivation is very much related to the above point. We launched our VMware vCloud™ initiative just over a year ago to develop an ecosystem of telecom, hosting, and service providers that offer cloud solutions based on VMware technologies. This ecosystem has grown by leaps and bounds, quickly surpassing 1,000 members. Today we offer this ecosystem VMware vSphere-based compute and storage infrastructure upon which they can offer what is commonly referred to as “infrastructure-as-a-service” (IaaS). With the acquisition of SpringSource, we can enable our partners to offer a higher level of cloud-based service; one where programmers can write their code and let the cloud handle the details of how and where it runs. This is commonly referred to as “platform-as-a-service” (PaaS). And with Zimbra, we will now offer our partners an even higher level of cloud capability; one where customers can simply use an application without worrying about the details of how and where it runs. This top layer of the hierarchy is known as “software-as-a-service” (SaaS).

With the coming acquisition of Zimbra I think VMware is trying to fight of their link with Microsoft and deliver a total package without being bound to a Microsoft operating system or Exchange implementation. This might be a smart move in the ongoing hypervisor battle because the Microsoft marketing machine is coming weather we like it or not.

For the complete article from Steve Herrod look here.

Oracle VM, things they do not tell

Last week a colleague, who sells applications running on an Oracle Database, had some questions regarding Oracle and running it in a Virtual Machine (VM) on top of a VMware infrastructure with a customer.

1) How to license Oracle in a virtual environment?

I pointed him to an article about licensing the Oracle software in a virtual environment I wrote some time ago.

Oracle can namely be hard- and soft partitioned, where VMware, XenServer, Hyper V and Oracle VM are all marked as soft partitioning, while looking into the way Oracle VM can be hard partitioned I stumbled on the following how to do it:

There are two methods to pin virtual CPUs. You can use the xm command to pin a guests’s virtual CPUs or you can hardcode the CPU mapping in a guest’s vm.cfg file. The difference between pinning CPUs with xm and hard coding the CPU mapping in a guest’s vm.cfg file is the persistence of the CPU mapping. CPUs that are pinned with xm are not persistent between reboots. Hard coding the CPU mapping in a guest’s vm.cfg file is persistent between reboots. To comply with Oracle’s hard partitioning policy, you must hardcode the CPU mapping in a guest’s vm.cfg file.

Deciphering the Cisco 3750 product code

When designing a virtual infrastructure an important bit in the design is the storage infrastructure also called the Storage Area Network (SAN). In a SAN based on iSCSI we often use Cisco 3750 switches, but when you are going to select the right Cisco 3750 for the job the fun starts. You will be dazzled by the amount of different product numbers and will be busy deciphering the product code.

The product code for a Cisco 3750 switch is build up like this:

WS-C3750a-xxbc-dee

WS stands for Switch
C stands for Catalyst series
3750 stands for the 3750 product line

a >> blank, G, E
blank = classic 3750 switch, 6.5 or 13.1 mpps forwarding rate
G = all ports are gigabit, 35 or 38 mpps forwarding rate
E = enterprise line, 65.5 or 101.2 mpps forwarding rate

xx >> 12, 16, 24, 48
12 = 12 Ethernet ports
16 = 16 Ethernet ports
24 = 24 Ethernet ports
48 = 48 Ethernet ports

b >> T, P, F, D, W
T = Ethernet ports
P = Power over Ethernet

The real value of Project VRC

About two weeks ago I attended a session at the VMware User Group meeting here in the Netherlands about Project VRC.  After the presentation I asked myself: ‘What is the value of this project?‘.

For you who don’t know what Project VRC is:

“Project Virtual Reality Check (VRC) is a joint venture of Log•in Consultants and PQR, who have researched the optimal configuration for the different available hypervisors (hardware virtualization layers). The project arises from the growing demand for a founded advice on how to virtualise Terminal Server and Virtual Desktop (VDI) workloads. Through a number of researches, Log•in Consultants and PQR show you the scaling possibilities for Terminal Server environments as well as Virtual Desktops.” http://www.virtualrealitycheck.net/

Don’t get me wrong: What they did was a very good initiative, it showed the performance differences between different hypervisors. Although the results were not that surprising it was good to see the validation numbers of the things we already knew.

I also think that the guys who did the project where totally surprised by the attention vendors and customers gave to the project. It was an outstanding (marketing) tool to show the value of virtualization and especially XenApp on a hypervisor. Because of this attention the whole project got out of hand. Although this was not the goal of the project, vendors and customers used it as a reference guide for vitalizing XenApp. That’s the point where I started to wonder what the real value of the project VRC was.

Best practices XenApp on vSphere

Based on the real life results when virtualizing XenApp I thought it was about time to summarize some of the best practices for virtualizing XenApp servers.

Why we DO want to virtualize XenApp?

  1. For server consolidation:  vSphere enables scale up XenApp deployments;
  2. For mixing server editions: 32-bit and 64-bit XenApp VMs can coexist;
  3. For management: Better management through flexibility & isolation think about Change Management and VMware DRS;
  4. For high availability and disaster recovery: VMware HA and vCenter Site Recovery Manager;
  5. For less costs for server hardware, maintenance contracts, power, cooling, floor and rackspace.

Virtualizing XenApp servers is very complex. There are a lot more layers involved, like the type of hardware, the capabilities of the processor, the performance of the shared storage, the hypervisor used, the specific settings per hypervisor, operating system settings in a virtual environment, the XenApp settings in a virtual environment, the Workspace management settings in a virtual environment etc, etc.

In the following sections I tried to summarize some of the best practices we use in our projects:
