While the costs of managing a data center are becoming a major concern with the increased number of under-utilized servers, customers are actively looking for solutions to consolidate their workloads to:

• improve server utilization
• improve data center space utilization
• reduce power and cooling requirements
• lower capital and operating expenditures
• reduce carbon footprint, ..

To cater those customers, Sun offers several virtualization technologies such as Logical Domains, Solaris Containers, xVM at free of cost for SPARC and x86/x64 platforms.

In order to help our customers who are planning for the consolidation of their MySQL databases on systems running Solaris 10, we put together a document with a bunch of installation steps and the best practices to run MySQL inside a Solaris Container. Although the document was focused on the Solaris Containers technology, …

I’m speaking at the User Conference this year, with a half-day tutorial and three further sessions. The running theme is performance, both in terms of the performance of your queries, and in terms of scaling up.

Scale Up, Scale Out, and High Availability: Solutions and Combinations

This is the big tutorial. It’s difficult to resolve what I’ll be talking about into a few sentences, but think about all of the different technologies available here - replication, partitions, sharding, DRBD, memcached - I’ll be talking about all of them, and more importantly combinations of the different solutions and where the potential performance gains and pitfalls are. I’ll also be using the opportunity to demonstrate some of the more obscure combinations that you can use to provide the environment you need.

Here is my experience trying to run OpenBSD with XenServer 5 Enterprise.

• XenServer console doesn’t function properly as it keeps overlaying text displayed previously or anything you have typed into the console. Makes it very difficult to read and see what you are doing. As well it appears numerpad with numlock on does not work either. The best work around is to SSH into OpenBSD.
• Receiving the following error messages at boot up, “clock: unknown CMOS layout” and “rl0: watchdog timeout”. Yes the NIC is being detected as a Realteak 8139. If I check /var/run/dmesg.boot out of the two error messages I only see the “clock: unknown CMOS layout”. So I would assume the watchdog timeout message occurs after initial boot sequence.

VirtualBox is really nice, but if you’re like me, maybe you found the networking confusing. There are three ways to do it, as explained by the manual, and the best way is with host interfaces, which don’t have limitations like the inability to ping and so on. I found what I think is [...]

Update: Sun has expanded its Cloud Computing portfolio with the recent acquisition of Qlayer, a cloud computing company that automates the deployment and management of both public and private clouds.  The Q-layer organization, based in Belgium, is now part of Sun's Cloud Computing business unit which develops and integrates cloud computing technologies, architectures and services.

Cloud computing is about managing petascale data. Sun's server and storage systems can radically improve the data-intensive computing emerging in the cloud. Some clouds are closed platforms that lock you in. Sun's open source philosophy and Java principles form the core of a strategy that provides interoperability for large-scale computing resources.

or timebound ? or don't you have any load on your DB at all ?

I personally don't see many reasons to virtualize your database, apart from the , we plan to start small and scale out, or the we need it now and we don't have the hardware yet , putting your database on a virtual platform where you have to share resources with other virtual machines doesn't really sound like a tempting proposition to me. Small, almost idle databases , maybe. But enterprise production level databases no thnx.

Sheeri Cabral also mentions the above reasons .. and there also .. Enterprise Production use isn't listed.

Databases typically require a good amount of memory , and steady disk access.
So if you are in a production environment with a fairly loaded database, would you want a 4Gb machine with full direct memory access, Or 3.5Gb of virtual …
