UCS X-Sequence – The Way forward for Computing – Half 1 of three


Now that Cisco’s UCS X -Sequence launch is behind us, I needed to debate the tenets that formed the product structure of UCS X- Sequence. It has been greater than decade since Cisco launched our UCS platform, a newcomer into the well-established enterprise server market. Relaxation is historical past. What has modified since then?

Shift in the direction of Heterogenous Computing

The earlier decade of computing was all about convergence. Protocol maturity of SAS & Fibre Channel  made them the goal to get converged on the ever present Ethernet cloth. Knowledge storage entry instances in milliseconds had been the cutting-edge.  CPU cores had been the principle execution ingredient. As the last decade progressed, storage protocols equivalent to NVMeoF began changing the normal SAS/FC.   With little or no protocol overhead over native gadget latencies of SSD, knowledge entry transitioned from milliseconds to microseconds and decrease.

Whereas Moore’s legislation and optimized algorithmic programming is shortening the software program execution instances, placement of information is essential to derive most profit. Core explosion is occurring, however feeds AKA interconnect is sluggish to evolve.   All of that is placing stress on the general-purpose homogeneous computing mannequin, the place a CPU core is on the heart of every little thing.  Software programmers’ quest for working on the absolute best {hardware} is main @macro stage,  rising use of hybrid cloud computing. Then again, @micro stage, there’s a paradigm shift occurring from homogeneous computing to heterogeneous computing. Heterogeneous computing depends on Workload optimized compute islands equivalent to AI/ML accelerators, accelerated computing, storage computing & reminiscence pool with conventional CPU cores working a part of utility.

Architectural Problem

This brings challenges on methods to construct a environment friendly structure with such a divergent compute wants additionally being prepared for  necessities which are tough to foretell prematurely?  What cloth decisions will handle IO latencies from milliseconds to nano seconds?  Ought to there be one cloth or multi cloth structure?  The “X” within the Cisco UCS X-Sequence has been designed to fulfill the current computing wants in addition to evolving use instances & past.

In addition to IO interconnects, class main Important statistics equivalent to energy, thermal efficiency & superior blade quantity units  UCS X- Sequence  aside from competitors. Proper sizing  these features with out sacrificing the compute density and future  energy scaling was a problem that required iterative course of.  Formfactor is sticky in the course of the lifetime of the chassis whereas the structure should be agile to accommodate altering compute wants.

UCS X-Sequence isn’t just a {hardware} product launch.  As an example, how does one provision & handle these divergent assets, whereas permitting for enough debuggability? Product success is determined by abstracting away the underlying complexity to offer a easy interface for the top customers. Cloud managed -Cisco Intersight administration platform is the important thing ingredient of this UCS X-Sequence structure bringing  within the much-required simplicity.

Within the subsequent publish, we are going to delve into key traits that drove electromechanical features  of UCS X- Sequence platform.
