Recent Virtualization PapersVirtualization Related BlogsServer Virtualization - Creating IO Domains on T5440
If we refer to the System Topology diagram in my previous blog, we find that the internal disks of T5440 are connected to PCIe-0. Hence it is not possible to remove the PCIe-0 from the Primary (or Control) Domain. However it is possible to remove PCIe-1, PCIe-2 and PCIe-3 from the Primary Domain and allocate them to IO Domains. Server Virtualization - Using LDOMs on T5440
The Sun Fire T5440 can have at most 4 UltraSPARC T2 processor. Each UltraSPARC-T2 Procesor is directly connected to ¼th of the entire system memory with 1Gigabyte memory interleaving and owns a PCIe Root-Complex. When fully populated with Processor and memory, Solaris can see 256 CPUs and 512GB of memory. That is a lot for many applications except for some large databases. With this class of system, it is not usually possible to consume the entire system with a singe instance of most applications. But that is in fact a very good opportunity to consolidate a bunch of such applications in this system using LDOMs, there-by reducing Power consumption and rack space. The BUI, or how Sun learned to stop over-thinking and love the customer
There are a lot of things that Sun is known for doing well. Shiny hardware, open-source software, excellent April Fools Day pranks. But user interfaces are generally not placed on that list. Honestly, our UIs have, in the past, probably gone on the opposite list. Sun Ray Bandwidth Monitoring Scripts
Kent Peacock, one of our illustrious Senior Engineers who helped give birth the to Sun Rays almost 10 years ago in Sun Labs has some great scripts that we use internally for watching how much bandwidth Sun Rays use. I asked him if it would be OK to share these scripts with our user community and he said "Please do!". An Update on xVM Ops Center 2.0
One of the coolest things about the forthcoming xVM Ops Center 2.0 is that it shares a common set of UI metaphors with the embedded xVM Server user interface. In fact, one could go so far as to say each copy of xVM Server embeds a slimmed down, for both features and footprint, optimized copy of Ops Center 2. All of your questions answered
Some folks here at Sun have put together a white paper giving a high-level overview of Sun xVM and how it all fits together. If you're curious about the bigger picture for Sun xVM, and how Sun xVM Ops Center, Sun xVM Server, Sun xVM VDI, and Sun xVM VirtualBox fit together, it's a good read. How do I know if I can virtualize my application using Sun Virtualization?
Somebody asked me the other day, "How do I know when to use which Sun Virtualization Technology and how do I know if I can virtualize my application?" Well it depends on what problem your are trying to solve. The following are a some general rules of thumb that I use and I though I would share them with you. Consolidation Technologies - One Size Doesn't Fit All
So, which technology approach is best for a given use case? The answer is "it depends". It's important to carefully consider your workloads technical and operational requirements as well as your organization's technical depth and operational maturity. |
