Now that Cisco’s UCS X -Sequence launch is behind us, I wished 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 material. Knowledge storage entry instances in milliseconds had been the cutting-edge. CPU cores had been the principle execution aspect. As the last decade progressed, storage protocols reminiscent of NVMeoF began changing the normal SAS/FC. With little or no protocol overhead over native system latencies of SSD, information entry transitioned from milliseconds to microseconds and decrease.
Whereas Moore’s regulation 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 part. Utility programmers’ quest for operating on the very best {hardware} is main @macro degree, rising use of hybrid cloud computing. However, @micro degree, there’s a paradigm shift occurring from homogeneous computing to heterogeneous computing. Heterogeneous computing depends on Workload optimized compute islands reminiscent of AI/ML accelerators, accelerated computing, storage computing & reminiscence pool with conventional CPU cores operating a part of software.
Architectural Problem
This brings challenges on how you can construct a environment friendly structure with such a divergent compute wants additionally being prepared for necessities which can be troublesome to foretell upfront? What material selections will handle IO latencies from milliseconds to nano seconds? Ought to there be one material or multi material 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.
Apart from IO interconnects, class main Very important statistics reminiscent of energy, thermal efficiency & superior blade quantity units UCS X- Sequence other than competitors. Proper sizing these points with out sacrificing the compute density and future energy scaling was a problem that required iterative course of. Formfactor is sticky throughout the lifetime of the chassis whereas the structure should be agile to accommodate altering compute wants.
UCS X-Sequence is not only a {hardware} product launch. For example, how does one provision & handle these divergent assets, whereas permitting for ample debuggability? Product success will depend on abstracting away the underlying complexity to offer a easy interface for the top customers. Cloud managed -Cisco Intersight administration platform is the important thing aspect of this UCS X-Sequence structure bringing within the much-required simplicity.
Within the subsequent put up, we’ll delve into key tendencies that drove electromechanical points of UCS X- Sequence platform.
