VMware Acquires Zimbra

I was stunned as I read this morning that VMware Acquires Zimbra. Just a few years ago, Yahoo! bought this open source email and collaboration suite. Zimbra is a kind of open source Exchange server that uses open standards where MS Exchange uses proprietary closed formats to store your mail and calendar. You can use any client, desktop or mobile, to check your mail, calendar or contacts and work together on documents with coworkers. Zimbra is similar to Zarafa, in that is also replaces the expensive Exchange server, but Zarafa introduces an interface to Microsoft's MAPI layer. The interface exists for many platforms.

MediaWiki Appliance from Turnkey Linux

At work I run a few wikis and while I could install/config the thing myself, I was using an old Linux version, did not have the time to tweak the OS and needed a wiki badly. I had been using an external wiki but security objected and I needed to move it. So I used the rPath mediawiki. But rPath is a bit custom if not proprietary. It's seldomly updated and perhaps even not maintained anymore.
So I found a new MediaWiki Appliance. This one's from Turnkey Linux, based on Ubuntu (Hardy), updated in the main stream and only 180 MB large. :)

Going to investigate it but it seems to solve all my previous gripes...

16,000 Exchange mailboxes on one server with VMware

VMware and IBM showed at VMworld 2008 how to 16,000 Exchange mailboxes on one physical server. They ran ESX 3.5 to host 8 VMs, each with 2000 mailboxes on 2 cores and 14 GB of RAM. Utilizing VMware's transparent page sharing allocated a total of 140 GB RAM and kept each guest humming along nicely, within Microsoft's recommended 1000ms latency threshold. Coool!

Update: server was IBM x3850M2 (quad quad-core), with 128GB RAM and 255 spindels on a cheap EMC Clarion SAN box. VMs were configured to run 1000 mailboxen per kernel, as recommended by Microsoft. MS Load generator was used to generate traffic with the Outlook 2007 online profile, heavy with pre logon.

VMworld 2007 report

Wanted to write this too, but virtualization.info already has it and did a good job! Live from VMworld 2007: Day 1. Lists all major things. Same thing for today, Day 2.

Intel Virtualization Technology for Directed I/O

Had a keynote of Intel today at VMworld2007. Learned a lot of new acronyms and that virtualization is only starting. The concept is now main stream, granted, but what we know and do with virtualization is only the beginning.
VMware has shipped ESX 3i, which is only 32MB in size and contains the hypervisor. So new hardware can become an ESX in the time it takes to boot! B) However, hardware support for virtualization has just begun. Intel is adding VTD, VMDQ, VTX and VTI to all new CPUs starting next year. This alleviates even more intermediate layers and increases performance even further. Especially network and disk I/O can use some assistance this is exactly what Intel's doing. Many of its developments assist VMware's VMM in delivering the right information to the right VM in as little time and with as little CPU overhead as possible... Now I wander what AMD will do... :) Read an Intel report on Virtualization Technology for Directed I/O (VTD) for details.

Update: forgot to mention FlexMigration

VMworld 2007

Woohoo! VMware invited KPN to come to VMworld 2007. As of September 1st, I work for KPN again and they sent me. :) Just booked the flight, now it's trying to find a hotel in a city just one week before a major event... fat chance! :( We'll see...

Citrix buys XenSource

I just got back on my chair after reading on the Register that Citrix buys XenSource, the affordable open source VMware competitor. And this despite the big share Microsoft has in XenSource. Plus, they launched XenEnterprise 4.0 yesterday...
/me still amazed

Veeam FastSCP for VMware

Ever need to copy or transfer large quantities of files to an ESX server? It's bad. First, it depends on your uplink to the servers. Second, copying normal data to VMFS partitions locks them and renders the server basically useless. This is where Veeam FastSCP for VMware comes in handy. As a friend of mine said: "In the case of the 'Uuh' factor, this is an 'uuuuuuuuuuh' ". :) 'nuf said

3D Graphics in VMware Fusion for Mac OS X

A friend showed me a YouTube video of 3D Graphics in VMware Fusion for Mac OS X. Amazing! They have DirectX 8.1 virtualized!

VMware Virtualization for MAC OS X - VMware

While playing with the Mac, I also installed OpenOffice.org so I can open some files people send me. I synced my entire phone over bluetooth with iCal and I installed VMware Fusion, giving me VMs in OS X! Works like a charm! I'm impressed.

What is VMware VDI?

The guys at MSTerminalServices have a decent, detailed description of what Vmware's latest attempt at desktop virtualization, VDI, is.
It works much like Citrix or MS's own Terminal Services but capitalizes on the existing, known, stable and managed ESX server infrastructure. Clever...

Playing with OLPC in VMware

There is a VMware virtual appliance with the OLPC virtual machine so you yourself can play with the new interface of the $100 laptop aimed at children in developing countries. Just download the image, get VMware Player (free) and see for yourself what children will be using.

VMProfessional

Today, I passed my VCP-101v exam and became - or will become very soon - an official VMProfessional. W00t! I had 78 out 80 questions right. The exam wasn't hard per sé, but the questions were very tricky. I did better than expected. :) There were silly questions that didn't really matter and won't make a better or worse Vmware consultant if you know the answer or not. There were also sneaky questions where you had to choose which answer was right, but there were 3 right answers. So which is the most right...? Anyway, intuïtion serves best I guess, although I reviewed some 15 answers before hitting "done".

IBM accelerates push into 3D virtual worlds

IBM will invest $10 million in virtual 3D worlds. 10 years ago, 3D worlds were all the hype too, however nowadays our PC can actually handle all the 3D things quite well.
Apparently, IBM already has 250 employees running around online and deals with 20 clients inside Second Life, a popular 3D world with over 1 million registered users. IBM wants to expand its use of 3D worlds and will invest in a virtual on its intranet to discuss sensitive information.

VMTN - Ultimate Virtual Appliance Challenge Winners

VMware annouced the winners of the Ultimate Virtual Appliance Challenge. It was a contest to see who could build a really useful and easy to use virtual server that was really useful. The FreeNAS server I am using at home won in the category Consumers. W00t! Congrats to Olivier!

VMware VCP training

vmwareCool, today I'm starting a 4 day training for VMware ESX server. W00t! Very cool! It can do sooo much more than I thought (Duuh!).
I hope I can get my VCP certificate this month, if the TU Delft project gives me enough time. The month of May has been a bitch, time-wise, so far...
Learnt some cool utils for ESX server: vmktree, which resembles vmkusage. esxRanger and esxCharter to resp. help you make hot replicates of an ESX server's VMFS volumes and report on ESX usage (important for managed when you need an additional ESX server ;)

VMware Introduces Free GSX Server

It's true: VMware Introduces Free GSX Server. Cool! The virtualization battle is heating up...
"In the left corner: MS Virtual Server, the proprietary giant. In the right corner: the reigning champion VMware... In the other left corner: XEN, the open source boy-wonder!" LOL :D

OpenSUSE 10.0 on my laptop

opensuseWell, it took a little longer than expected... a 6 Mbit downlink is only so fast. But I finally have replaced SuSE 9.5 (originally SuSE 9.3 Pro but upgraded to OpenSUSE 10.1 using CDs and online patches) with OpenSUSE 10.0 stable.
I had repartinioned my harddrive to using an 8 GB root partition with the rest in a logical drive (25 GB) and a 1 GB FAT32 partition to exchange data with Windows XP running in VMware workstation, so I simply popped the 70 MB OpenSUSE network install and selected a fast mirror (thanx to belnet.be!) and downloaded 5 GB of software in about 2 hours. I just completed installing Thunderbird and Java and some misc packages, so now I'm up and running again. And I must say... my little HP nx9030 is now lightning fast compared to my old patched SuSE 9.5 system... :)

Debian -- The Universal Operating System

OK, it took me 2 months but I knew the day would come sooner or later. I now have dumped SuSE at work for everything except desktops and test & play servers (inside VMware) and I'm running Debian -- The Universal Operating System on my barebone, basic, stable, mission-critical server! B) Finally. Now why wouldn't they listen to me sooner... *sigh* Apache, Postfix, DNS... rock solid!
