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

This low level software allowed multiple applications to run on the same physical hardware but believe that they had the box all to themselves. Things like what operating system an application used no longer mattered – you could mix and match to your heart’s content.

Solarflare’s Open Compute Platform, Software-Defined, NIC Card

CTOvision

This is the industry’s first universal kernel bypass (UKB) solution which includes three techniques for kernel bypass: a POSIX (Portable Operating System Interface) sockets-based API (Application Program Interface), TCP (Transmission Control Protocol) Direct and DPDK (Data Plane Development Kit). Other capabilities include: Hardware Based Packet Telemetry. Hardware Based Security (ServerLock). Unique hardware filter tables for each adapter hosted IP address.

The New Storage Buyer

Chuck's Blog - EMC

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.   And to help achieve this, they’re looking for converged platforms: both hardware and software.

IDF 2013: Future of SDN with the Intel ONP Switch Reference Design

” The speakers are Recep Ozdag, a PME with Intel, and Gershon Schatzberg, a PLM with Wind River Systems. Recep will cover the hardware side of ONP; Gershon will cover the software side of ONP (referred to as ONS). From the operator’s point of view, network virtualization allows each tenant (or customer) to see a single network switch that is specific to that tenant or customer. ONP fits into this picture by performing VTEP functions in hardware (at line rate).

First up is Brent Salisbury’s how to build an SDN lab without needing OpenFlow hardware. Not unsurprisingly, one of the key advantages of STT that’s highlighted is its improved performance due to TSO support in NIC hardware. Related to the bare metal provisioning work (see below under “Servers/Hardware”), Mirantis also detailed some bare-metal networking stuff they’ve done for OpenStack in relation to the use of bare metal nodes.
