CIOs Need To Realize That Virtualization Isn't All That It's Cracked Up To Be (a chief information officer needs an IT strategy to create IT alignment)

The Accidental Successful CIO

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.

The New Storage Buyer

Chuck's Blog - EMC

Present newer concepts around software-defined storage (SDS) to a traditional storage group, and you’ll mostly get polite interest and head-nodding, rarely more.  As the network world has started to debate the merits of SDN (software-defined networking) as compared to the hardware-defined alternative, the storage world has started to do the same. While it’d be certainly convenient to have an authoritative definition of software-defined storage, no such luck.

For a start, it provides easy optimization of infrastructural resources since it uses hardware more effectively. The isolation containers enable users to run their software consistently across environments, ?n As a result, this considerably simplifies and speeds up the software development and release process, bringing a faster time-to-market. Therefore, this allows users to save on hardware and data center costs. Traffic routing and load balancing.

The ability to virtualize the network devices such as firewalls, IPS and load balancers also means that these once physical devices that have discrete interfaces can be controlled by software. Since they can be provisioned and configured by software means that they can now be automated using vCAC and vCD. The question is if IT has the ability to implement and support a physical data center let alone a Software-Defined Data Center (SDDC).

This is session COMS002, titled “The Future of Software-Defined Networking with the Intel Open Network Platform Switch Reference Design.” Recep will cover the hardware side of ONP; Gershon will cover the software side of ONP (referred to as ONS). ONP fits into this picture by performing VTEP functions in hardware (at line rate). Some of these services naturally should run on the top-of-rack (ToR) switch, like load balancing or security services.

On Network Virtualization and SDN

Scott Lowe

Is there a difference between network virtualization and Software-Defined Networking (SDN)? I encourage you to read Keith’s full blog post, but I think the key point he makes is right here: How is this different from Software Defined Networking or SDN? Think about it: existing protocols like OSPF and BGP (which run in software ) manipulate the forwarding rules in the data plane—does that make them SDN, too? These are all software—does that make them SDN?

Fountainhead: IO Virtualization: The ?Hypervisor? for Your.

Fountainhead

Existing physical IO but with address hardware-based mapping/virtualization (e.g. You should think of IOV using the following analogy: The way in which the hypervisor abstracts software in the application domain, IOV abstracts IO and networking in the infrastructure domain. However, to be clear, IOV is not a software layer as-is the hypervisor). This provides a ‘universal’ style of failover that doesn’t require clustering software.

Fountainhead: Emergence of Fabric as an IT Management Enabler

Fountainhead

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. can all be simplified and accomplished via software as well. Software being either a virtual host, or a traditional native OS).

As a provider, Expedient has to balance five core resources: compute, storage (capacity), storage (performance), network I/O, and memory. 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.

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. And I mean I/O components like NICs and HBAs, not to mention switches, load balancers and cables. Also remember that with few moving (physical) parts, you also have to purchase few software tools and licenses.

Tom’s key point is that disaggregating software from hardware—which is kind of a given if you’re buying whitebox networking gear—gives you the (potential) flexibility to repurpose network gear based on the software running on it. 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. Servers/Hardware.

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 early GPU systems were very vendor specific and mostly consisted of graphic operators implemented in hardware being able to operate on data streams in parallel. The different stages were then load balanced across the available units.
