Johnson shows a great diagram that reviews all the various types of VM-to-VM communications that can exist in modern data centers: VM-to-VM (on the same host) via the software-based virtual switch (could be speeds of 30 to 40 Gbps in this use case). In this case, the switching is done in hardware in the SR-IOV NIC.

Each has a differing technology approach to blade repurposing, and each differs in the type (and source) of management control software. The UCS Manager software bundled with the system provides core functionality (see diagram, right). As sophisticated as it is, in contrast to HP, this software is essentially "1.0" Blog Archive.

Parallel processing can be achieved through shared memory, distributed memory, or hybrid parallel processing, which are discussed in more detail later in this blog. To address scalability problems, parallel processing systems use load balancing algorithms to distribute tasks evenly among processors and ensure optimal performance.

The arrival of virtualization software changed everything. This low level software allowed multiple applications to run on the same physical hardware but believe that they had the box all to themselves.

A specific angle I want to address here is that of infrastructure automation ; that is, the dynamic manipulation of physical resources (virtualized or not) such as I/O, networking, load balancing, and storage connections - Sometimes referred to as "Infrastructure 2.0". a Fabric), and network switches, load balancers, etc.

Craig Matsumoto of SDxCentral recently published a piece on NFV performance ; that article was based largely on a blog post by Martin Taylor of Metaswitch found here. The “gotcha” is that these software stacks haven’t been written yet, so the idea of repurposing hardware from switch to firewall to load balancer is still a bit of a unicorn.

Essentially the punchline is this: Weve taken the most commonly-purchased hardware configuration and management tools used by mission-critical IT Ops, and integrated them into a single product with a single GUI that you can install and use in ~ 1 day. If you dont believe Dell hardware is ready for the Data Center, then think again.

This blog is related to my 2009 installment on Fabric as an IT Enabler. Existing physical IO but with address hardware-based mapping/virtualization (e.g. However, to be clear, IOV is not a software layer as-is the hypervisor).

If you’re interested in learning more about OpenFlow and software-defined networking but need to do this on a shoestring budget in your home lab, a number of guides have been written to help out. First up is Brent Salisbury’s how to build an SDN lab without needing OpenFlow hardware. Servers/Hardware. Networking.

other than managing your software stack). Capital cost – if you count all of the separate hardware components they’re trying to manage. That last bullet, the thing about hardware components, is also something to drill down into. The result: Buying, integrating and maintaining less software. See diagram below.

This is very much analogous to how OS virtualization componentizes and abstracts OS and application software stacks. The next step is to define in software the converged network, its switching, and even network devices such as load balancers. Provisioning of the network, VLANs, IP load balancing, etc.

Converged Infrastructure and Unified Computing are both terms referring to technology where the complete server profile, including I/O (NICs, HBAs, KVM), networking (VLANs, IP load balancing, etc.), and storage connectivity (LUN mapping, switch control) are all abstracted and defined/configured in software.

Modern CPUs strongly favor lower latency of operations with clock cycles in the nanoseconds and we have built general purpose software architectures that can exploit these low latencies very well. The different stages were then load balanced across the available units. Also more details can be found on the AWS Developer blog.
