Many of the virtualization customers I speak with have been asking about what database can be virtualized, so I typically present a green, yellow and red set of criteria to help guide the process. We typically look at I/O rates, SMP width and capacity of the source physical system as ...

In a stark contrast to recent past when Solaris Internals was hosted on physical machines, we've just experienced one of the core values of virtualization -- encapsulated, portable state allowing geographic mobility. Solaris Internals has over the last two weeks been teleported out of my datacenter (As Jim notes, the ...

[ there was a bad youtube server hosting the first video, so here's a resubmit with a pointer to an alternative youtube copy
It's been well talked up that consolidating physical systems can save a lot of datacenter engery -- for example, consolidating 20 systems, all with 3-5% utilization can reduce ...

It's been well talked up that consolidating physical systems can save a lot of datacenter engery -- for example, consolidating 20 systems, all with 3-5% utilization can reduce power by up to 10-15x -- or considered in more tractable terms, each server removed is equivalent to taking four cars off ...

We're really excited to announce that we hit over 100k IOPS!
This was done using 77TB of storage, adding a 3rd rack totalling 495 disks -- enough storage to hold the entire printed library of congress, and all being driven from a single ESX server!
Chethan's just written a detailed report over ...

We've doubled the number of disks, totaling just over 300, taking up two entire CX-380 racks..
That's 44TB of disk, and enough spindles to drive over 100,000 exchange users...
More disks are on the way...

We're at Santa Cruz this week at the workshop for file system benchmarking. , chaired by Erez Zadok of StonyBrook University.
The objective of this week is to converge on a set of strategies and recommendations towards more accurate and representative benchmarking of file systems and storage.
Many of the File Systems ...

We now starting to see some of the more enterprise-league I/O rates... In contrast to the simple NVRAM cached 3 disk configurations used in the previous posts, we've moved to one of the more typical SAN based setups used for running the bigger applications. In this case, we now have ...

This result is on a somewhat tiny system -- we are able to get 4013 iops from a Dell 1950 server with just 3 disks.
You might expect a somewhat smaller number with just 3 disks (like ~750), but these servers have a non-volatile cached storage RAID controller, which is able ...

Our engineers have been working on the I/O challenge...
They are using iometer as the workload generator -- it can faithfully produce a random I/O load on Windows, and small-random-io is typical of a database access. I'd love to use filebench, but we don't have a Windows port yet ...
