The Evolu@on of SoBware
• The @mes the are a changin (Thanks, Bob) • Much less about what the vendor gives you • Much more about what the business wants the applica@on to do, with a range of op@ons
• Influenced by open development • Influenced by compe@@on • Modularity is prolifera@ng

The Evolu@on of SoBware
• Many systems being replaced are from the monolithic era.
• New systems are typically much more externally dependent rather then request / result
• Custom Binaries in C have moved more and more to layered architectures, J2EE, Web+App+DB, message busses and more
• Ruby, Python, JAVA, C# -‐ all have considerable system level impact

Assump@ons of New SoBware
• New SoBware oBen makes New System assump@ons
• Much of the new soBware out there expects – Huge amounts of memory – Many threads – Very low latency interconnects – CPUs with hardware support for many func@ons

Solu@on when SoBware and Hardware are not a good match?

The Progression of Hardware
• CPU’s no longer gedng drama@cally faster in a straight line – but are gedng WIDER
• CPUs gedng more capability in silicone • Memory System bandwidth increasing – though latency is not improving
• Memory density increasing, but also not progressing nearly as fast as applica@ons can use it

The Progression of Hardware
• Interconnects have improved • Busses and loops have given way to fabrics (SAS, PCI-‐E, Infiniband)
• ‘Commodity’ is a commodity term. • Focus is oBen on CapEx – though oBen at the expense of OpEx.

Interconnects

Interconnects and caching
• 10Gbe Now, 40 and 100GbE coming soon • QDR Infiniband here now (40Gbps), EDR and FDR already releasing
• FLASH (Ah aaaaaah) • SoBware gedng much smarter about using @ers WITHOUT external assistance (eg: 11gR2 using flash directly)

Hypervisors are cool, right?
• To V or not to V! • Why do we Virtualize? • Regularly required because ‘the hardware is too big’, and because commodity hardware lacks many of the safeguards of Enterprise
• The an@thesis of what makes sense in ‘large systems’. S@ll has value (eg: Availability)
• Many and varied: Which should you use? When should you use them?

Clawing back the Datacentre
• Racks of old systems can be consolidated into RU’s of space
• Do in 200W what previously took 2000W • Legacy support costs can be crippling • Message passing speed of older plamorms (using PCI, PCI-‐X) are slower. Today is all about message speed
• Increased reliability: ECC, Checksums, etc.

Exclusive Convergence vs Solu@ons
• Many vendors have their own ‘convergence’ • Most are claimed to be designed with a ‘system’ approach in mind, and are pitched as a ‘architected solu@on’
• Many solu@ons are incompa@ble and force you into that vendors idea how it should be done.
• The Oracle value is that you can use best of breed components, OR allow Oracle to provide the en@re stack.

COST
• New hardware delivers more bang for buck • Oracle Core Factor -‐ .25 for T3, .5 for M-‐series and X86, 1 for P-‐series, and Itanium largely irrelevant! ;)

Lifecycle WIN vs Expenditure FAIL
• Infrastructure is typically only a small component of an IT project.
• It’s typically the one chance for a to change it’s deployment architecture and to get onto the latest and greatest hardware
• Provides the opportunity to build the right sized infrastructure rather than guessing
• CPU capabili@es will be tracking soBware developments. Eg: DB specific instruc@ons

It’s great news: Your applica@on can be fast.

Get the MOST from your SoBware
• Understanding your soBware helps architect a system to suit it
• Select the right CPU architecture type • Select the right memory architecture • Balance I/O • Use teiring intelligently, not just because you can
• Agility in deployment: Virtual versus Physical

Summary:
• Running new soBware on previous genera@on hardware is fraught with danger
• Many soBware assump@ons don’t stack up on old hardware
• Many applica@ons actually require instruc@on set support to run at their best
• To get the most from your soBware applica@ons, the best start you can give them is a fresh batch of @n.
