The Shape of Things to Come!

A Resurgent SPARC platform for Enterprise Cloud Workloads (Part 2) - SPARC T5

Some time ago, I blogged about the resurgence of the SPARC platform. The then newly designed SPARC T4 was showing tremendous promise in its own write to be able to take up its former mantle of being an innovation leader running extreme workloads with the Solaris 11 operating system.

Indeed, it was used as the driving engine of the SPARC Supercluster for dealing with not just massive acceleration of Oracle database workloads using the Exadata Storage Cell technology, but the ability to combine firmware embedded near-zero overhead virtualization concepts for electrically separate logical domains, carving up the physical hardware, and Solaris zones which allow near-native "virtual machines" sharing an installed Solaris operating system.

Up to 128 virtual machines (zones) supported on a system - a vast improvement over the 20-30 one gets under VMware-like hypervisors typically!

This welcome addition to the wider Oracle engineered systems family allowed the missing parts of the datacenter to be consolidated - these being typically glossed over or totally skipped when virtualization with VMware-like hypervisors was discussed. Customers were aware that their mission critical workloads were not always able to run with an x86 platform which was then further reduced in performance using a hypervisor to support large data set manipulation.

Well the rumor mills have started as the run up to Oracle Openworld 2012 at the end of September. One of the interesting areas is the "possible" announcement of the SPARC T5 processor. This is interesting in its own right as we have steadily been seeing the SPARC T4 and now the T5 having ever greater embedded capability in silicon to drive database consolidation and indeed the entire WebLogic middleware stack together with high-end vertical applications such as SAP, EBusiness Suite, Siebel CRM and so on.

Speculating on what "rumors" and the Oracle SPARC public roadmap, I'd like to indicate where I see this new chip making inroads in those extreme cloud workload environments whilst maintaining the paradigm of continuous consolidation. This paradigm that I outlined in a blog in 2010 is still very relevant - the SPARC T5 providing alternative avenues than simply following the crowd on x86.

Questioning "Datacenter Wisdom"

The new SPARC T5 will have, according to the roadmap the following features and technologies included:

  • Increasing System-on-a-Chip (SOC) orientation providing ever more enhanced silicon accelerators for offloading tasks that software typically struggles with at cloud scale. This combines cores, memory controllers, I/O ports, accelerators and network interface controllers providing a very utilitarian design.
  • 16 cores from the T4's 8-core. This takes them right up to the top end in core terms.
  • 8 threads per core - giving 128 threads of execution per processor providing exceptional performance for threaded applications such as with Java and indeed the entire SOA environment
  • Core speeds of 3.6GHz providing exceptional single threaded performance as well as the intelligence to detect thread workloads dynamically (think chip level thread workload elasticity)
  • Move to 28nm from 40nm - continuous consolidation paradigm being applied at silicon level
  • Crossbar bandwidth of 1TB/s (twice that of the T4) providing exceptional straight line scaling for applications as well as supporting the glueless NUMA design of the T5
  • Move to PCIe Generation 3 and 1TB/s memory bandwidth using 1GHz DDR3 memory chips will start to provide the means of creating very large memory server configuration (think double-digit TB of RAM for all in-memory workload processing)
  • QDR (40Gbps) Infiniband private networking
  • 10GbE Public networking
  • Database workload stacking becomes even more capable and effective than simple hypervisor based virtualization for datacenter estate consolidation at multiple levels (storage, server, network and licensed core levels)

This in itself at the processor level is really impressive, but the features that are on the roadmap aligned to the T5 possibly are the real crown jewels:

  •  on-die crypto accelerators for encryption (RSA, DH, DSA, ECC, AES, DES,3DES, Camellia, Kasum) providing excellent performance through offloading. This is particularly relevant in multi-tenant Cloud based environments
  • on-die message digest and hashing accelerators (CRC32c, MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512) providing excellent security offloading. Again particularly relevant in multi-tenant environments
  • on-die accelerator for random number generation
  • PCIe Generation 3 opens the door to even faster Infiniband networking (56Gbps instead of the current 40Gbps - with active-active links being possible to drive at wire speed)
  • Hardware based compression which will seriously reduce the storage footprint of databases. This will provide further consolidation and optimization of database information architectures.
  • Columnar database acceleration and Oracle number acceleration will provide extremely fast access to structured information. Further, when combined with in-memory structures, the database will literally be roaring !

Indeed when we think that the Exadata Storage cells will also be enhanced to support new chip generations, flash density as well as other optimizations, the next SPARC Supercluster (which has the embedded Exadata storage cells) will literally be one of the best performing database platforms on the planet!

To ignore the new SPARC T5 (whenever it arrives) is to really miss a trick. The embedded technology provides true sticky competitive advantage to anyone that running a database workload or indeed multi-threaded applications. As a Java platform, middleware and SOA platform as well as vertical application platform, the enterprise can seriously benefit from this new innovation.

Why is this important for the CIO & CFO?

CIOs and CFOs are constantly being bombarded with messages from IT that x86 is the only way to go, that Linux is the only way to go, that VMware is the only way to go. As most CFOs will have noted by now:

  • Financially speaking - the x86 servers may have been cheaper per unit, but the number of units is so large to get the job done that any financial advantage that might have been there has evaporated!
  • Overall end-2-end costs for those services that the CIO/CFO signed off on are never really well calculated for the current environment.
  • Focused investment on those activities that support revenue streams and those technologies that will continue to do that for at least the next decade with capacity upgrades of course
  • There must be other ways of doing things that make life easier and more predictable

Well Engineered Systems with the new SPARC T5 represent a way for the CIO/CFO to be able to power those projects that need investment which in turn drive revenue and value. The ability to literally roll the SPARC SuperCluster or any other Engineered System is going to be instrumental in:

  • Shortening project cycles at the infrastructure level
    • don't lose 6 months on a critical ERP/CRM/Custom application project in provisioning hardware, getting unexpected billing for general infrastructure layers such as networking that have nothing to do with this project, IT trying to tune and assemble, getting stuck in multi-vendor contract and support negotiations etc.
    • That time can be literally worth millions - why lose that value?
  • Concentrate valuable and sparse investment strategies literally to the last square meter in the datacenter!
    • If that next project is a risk management platform, then IT should be able to give exactly to the last datacenter floor tile the resources that are needed for that one project alone and the cost
    • Project based or zero-budgetting will allow projects to come online faster, predictably, reuse of existing platforms dealing with the load as well as supporting continuous workload consolidation paradigms
    • Finance enterprise architecture projects that put in the enabling conditions to support faster turnaround for critical revenue focused/margin increasing project activity
Engineered systems are already using the technologies that the rest of the industry is trying to re-package to meet the challenges customers are facing now and in the coming years.The lead is not just in technology but also the approach that customers are demanding - specific investments balanced with specific revenue generating high-yield business returns.

As a CIO it is important to recognize the value that Engineered Systems and the SPARC platform, as part of an overall datacenter landscape, bring in addressing key business requirements and ensure an overall simplification of the Datacenter challenge and large CAPEX requirements in general.

As Oracle and others proceed in acquiring or organically developing new capabilities in customer facing technologies, managing exabyte data sets it becomes strategically important to understand how that can be dealt with.

Hardware alone is not the only answer. Operating systems need to be able to deal with big thinking and big strategy as do applications and the hardware. By creating balanced designs that can then scale-out a consistent effective execution strategy can be managed at the CIO/CTO/CFO levels to ensure that business is not hindered but encouraged to the maximum through removing barriers that IT may well have propagated with the state of the art many years ago.

Engineered Systems enable and weaponize the datacenter to directly handle the real-time enterprise. High-end operating systems such as Solaris and the SPARC processor roadmap are dealing with the notions of having terabyte datasets, millions of execution threads and thousands of logical domains with hundreds of zones (virtual machines) each per purchased core.

Simply carving up a physical server's resources to make up for the deficiencies of operating system/application in dealing with workloads can't be an answer by itself. This is what is also fueling the Platform-as-a-Service strategies partly. How to get systems working cooperatively together to deal with more of the same workload (e.g. database access/web server content for millions of users) or indeed different workloads spread across systems transparently is the question!

High performance computing fields have been doing just this with stunning results albeit at extreme cost conditions and limited workloads. Engineered systems are facilitating this thinking at scale with relatively modest investment for the workloads being supported.

It is this big thinking from organizations such as Oracle and others, who are used to dealing with petabytes of data, and millions of concurrent users that can fulfill  requirements expressed by the CIO/CTO/CFO teams. If millions of users needing web/content/database/analytics/billing can be serviced per square meter of datacenter space - why not do it?
