Yeah, this is the one I’ve been waiting for a 9″ Asus Eee PC. The 7″ is a cool device, but lacks a decent screen resolution. This is probably fixed with the 9″. Asus has also added a 12GB flash disk instead of a 8GB flash disk. I really need to pick one up as soon as it becomes available in Europe.

VMworld, the aftermath
It’s been a weird couple of days. I arrived in Cannes with the flu. Especially Monday, but also Tuesday, I wasn’t in top condition to say the least. Same goes for my cellphone which for some reason decided to quit on me, apologies to the people that tried to reach me and got my voice mail instead. Besides these physical and technical problems VMworld was awesome! I’ve met a lot of cool people and attended a lot of cool sessions, especially the vendor sessions were great, EMC / Brocade / Netapp. Although I must say that it would be nice if VMware adds a few real in depth sessions which will leave your brain dazzled for days, for instance on VMotion/DRS/Networking/Storage.
What surprised me most were the products Stage Manager, Lifecycle Manager and Lab Manager. They all seem the same to me. There’s a slight difference here and there but the global idea is the same. Provision VM’s with the possibility to archive them, assign them to a team or people etc. I can imagine these products will merge into one product or at least Lab Manager and Stage Manager will. Lifecycle Manager should be turned into a plugin for VirtualCenter. I don’t have any hard evidence for this or even a remote clue… but this is what I would expect to happen over the next couple of months.
One of the most promising new products that I played with definitely is Site Recovery Manager. This will save a lot of time and money for the companies that now have to do a manual fail over when a disaster occurs. One of the things that Site Recovery Manager still lacks though is the “Fail Back” button, which definitely is a feature that should be included soon. If I can fail over automatically it would be very nice if I could fail back automatically, the test button is great but everyone should really test the fail over every once in a while and with out a fail back this will be very hard.
The two new announced “products” VMsafe and vServices both leave the competition light years behind again. Both products were in the line of expectations. VMsafe was already more or less announced when VMware introduced VMCI 6 months ago:
The Virtual Machine Communication Interface (VMCI) is an infrastructure that provides fast and efficient communication between a virtual machine and the host operating system and between two or more virtual machines on the same host. The VMCI SDK facilitates development of applications that use the VMCI infrastructure.
vServices is the next step for VirtualAppliances. This gives the system engineer a new view on his system, looking at the VM from a service perspective instead of a server perspective makes sense to me, especially when you consider most services span multiple VM’s/servers these days.
Also VDI/VDM is definitely a technology VMware heavily bets on. Especially the new “offline usage” feature and the “patch one patch many” feature is something that will attract all engineers. This will not only save a lot of time updating but also solves most Corporate Laptop problems we are currently facing. The Linked Clone option sounds awesome, but what will happen when a 1000 VDI Desktops running linked clones are accessing the SAN at the same time and expanding the linked clone file at the same time. (The 09:00 clock bubble) I can only imagine this would put an outrages amount of stress on the SAN, but only time will tell I guess.
So that’s it for now, I’m gonna spend some time with my family and will be blogging full speed again the upcoming days, and testing those 16.000 users on my Exchange server of course. Maybe one of you can hook me up with suitable test servers and SAN… ๐
VMworld here we come
In a couple of hours my colleague Remco and I will be flying to VMworld, Cannes. I will be leaving my laptop at home so no blogs over the next couple of days! I want to spend as much time as possible gathering information/knowledge and making new virtual contacts! ๐
Xen HA clustering
The company I work for, Ictivity, recently started testing with Xen(not Xensource!) and HA clustering. There were two case studies, one based on Suse and one based on Red Hat. Both definitely have it’s own advantages and disadvantages but it seemed promising to me. Today I noticed a blog on ONLamp.com about how to set this up. It’s a good read and gives you insight information. You can do this with open source only software so it will not get any cheaper than this. If this solution is suitable for an enterprise environment is definitely a point of discussion, but it is good to see there are more alternatives coming our way.
The idea of using virtual machines to build high available clusters is not new. Some software companies claim that virtualization is the answer to your HA problems, off course that’s not true. Yes, you can reduce downtime by migrating virtual machines to another physical machine for maintenance purposes or when you think hardware is about to fail, but if an application crashes you still need to make sure another application instance takes over the service. And by the time your hardware fails, it’s usually already too late to initiate the migration. So, for each and every application you still need to look at whether you want to have it constantly available, if you can afford the application to be down for some time, or if your users won’t mind having to relogin when one server fails.
Citrix Xenserver 4.1 Beta
Thincomputing.net just posted about a new Xenserver Beta. Looking at the new features list it seems things are finally getting up to speed, especially “bonding of NIC’s” is a must have in a enterprise environment. Hope you can also pin the live migration on a specific NIC in this release, but looking at the specs I don’t think it’s possible.
