Fixing the Broken Storage Model: A Storage Hypervisor At Last

Published on

Presence of a storage hypervisor on the back end allows disparate SAN products (iSCSI, fibre channel, or both) and local storage (including “JBOD” expansion shelves), plus a mix of SSD, SAS, and SATA drives to operate seamlessly and optimally. The storage hypervisor masks all complexities and presents a consistent resource – in the form of iSCSI virtual volumes – to the systems that need to consume storage both physical or virtual servers.

The sprawl and multiplication of storage systems and the rising number of specialty devices are now the norm. The intelligence of a storage hypervisor provides a strategic advantage to managing the many as one

Fixing the Broken Storage Model: A Storage Hypervisor At Last

  1. 1. Fixing The Broken Storage Model: A Storage Hypervisor At Last Jon Toigo CEO Toigo Partners International Chairman Data Management Institute
  2. 2. Welcome and Overview • Three questions to address: • What is the broken storageCopyright © 2011 by Toigo Partners International LLC. All Rights Reserved. model…and who broke it? • What is a “storage hypervisor?” • How can a storage hypervisor help? • All in 30 minutes! (Whew.)
  3. 3. Define “Broken” • bro·ken [broh-kuh’n]Copyright © 2011 by Toigo Partners International LLC. All Rights Reserved. – Out of working order, malfunctioning – Disunited or divided – Bankrupt, ruined, lacking efficiency • Storage technology is inefficient – From an engineering perspective – From an operational perspective – From a budgetary perspective
  4. 4. Copyright © 2011 by Toigo Partners International LLC. All Rights Reserved. CAPACITY TB+ (Areal Density = Gb per in2) Sub-MB1980 • Disk keeps getting bigger and cheaper, but… Engineering-wise ARRAY COSTS ACCELERATING2010 COST PER GB LOW HIGH Jon Toigo, Scientific American Source: “Avoiding the Storage Crunch,”
  5. 5. “Creeping Featuritus”- Blurring the Lines… 100Copyright © 2011 by Toigo Partners International LLC.

  6. 6. Why All of the “Value Add?” • Differentiation of otherwise commodityCopyright © 2011 by Toigo Partners International LLC. All Rights Reserved. hardware requires value-add functionality All drives and enclosures from – Publicly-traded OEMs must “innovate” (aka “add handful of OEMs value via software embedded on array controller”) every 6-8 months, or risk losing market analyst interest – Embedded software used to lock in customer/lock out competitors RAID dates to 1977: freeware – Portrayed as “one-stop-shop” or “pre-integrated” or “intelligent or smart(er) product” with purported TCO reduction value – Software costs nearly $0 to mass produce – a plus
  7. 7. Oh, and Value Add adds Profit • For example: A popular de-duplication solutionCopyright © 2011 by Toigo Partners International LLC. All Rights Reserved. vendor offers two kinds of de-duplication rigs A. Software only • Licenses software separately for $2500 per TB • Run on a server, use any storage you have B. Software plus hardware • 32 TB of commodity SATA disk storage with embedded software = $410,000 MSRP (or $12,812.50 per TB) • 1 TB SATA disk costs $79 - $140 on NewEgg.com (~$3200 for 32 TB) • Vendor’s “value-add” rig costs $80K for software, $330K for disks or 100x the cost of the disks themselves
  8. 8. Copyright © 2011 by Toigo Partners International LLC. All Rights Reserved. Resulting Infrastructure
  9. 9. Not to Mention • Inflexible infrastructure design in the face ofCopyright © 2011 by Toigo Partners International LLC. All Rights Reserved. changing workload demands • Higher failure rates because of incomplete interoperability testing matrix data • Scaling challenges (services and hardware) • Performance challenges • Lack of predictability (units of storage)
  10. 10. From the Operational Perspective • Heterogeneous “value-Copyright © 2011 by Toigo Partners International LLC. All Rights Reserved. add” storage is making life miserable – No unified cross-platform management capability for “meta-management tasks” • Capacity • Performance • Data protection – No unified management for “hardware and plumbing” to facilitate troubleshooting or tuning
  11. 11. Last Year… • Roughly 7% of 40.5M disk drives failed = 2.8M drivesCopyright © 2011 by Toigo Partners International LLC. All Rights Reserved. – per Google, Carnegie Mellon and IDC reports • Downtime from outages at 3000 US/European firms = 127M hours (like paying 65,000 persons full time wages for a year-long holiday from productive work) – per a study commissioned by CA Technologies • The annual operational costs of storage (administration, manual management, environmentals) were 4x the cost of hardware acquisition (and firms currently implementing server and desktop virtualization are expected to grow their storage infrastructure capacity 600% over the next three years) – per Gartner
  12. 12. Not Surprising, The Bean Counters Aren’t Thrilled about the Cost… • From a financial perspective, storage cost looks like aCopyright © 2011 by Toigo Partners International LLC. All Rights Reserved. nail in search of a cost cutting hammer… Or maybe, something better outsourced to “clouds”… (Got C.V.?)
  13. 13. Copyright © 2011 by Toigo Partners International LLC. All Rights Reserved. 33-70% Storage is Financially Inefficientof the IT hardware budget…
  14. 14. Add to That… Warranty and maintenance agreement costsCopyright © 2011 by Toigo Partners International LLC. All Rights Reserved. • • Annualized value-add software license costs • Installed “hot spare” drives • “Signed drives” • Wire, switch, HBA/NICs… Few other industries make as much money by cutting down their product…
  15. 15. Copyright © 2011 by Toigo Partners International LLC. All Rights Reserved. And CAPEX is only a Fraction of Storage Total Cost of Ownership…
  16. 16. Copyright © 2011 by Toigo Partners International LLC. All Rights Reserved. • So, what is the latest advice? “Unsustainable”

The x86 Server is a commodity… Applications and operating systems don’t care about the brand of gear on which they are hosted. Software is portable… Server hardware is just a building block with known resources and performance capabilities.

  24. 24. Equally Applicable to a Storage Hypervisor…Copyright © 2011 by Toigo Partners International LLC. All Rights Reserved. Media capacities and interfaces aside, storage arrays are commodity gear… Most value-add applications don’t need to be hosted on HW array controllers. Software is portable… Storage hardware is ideally just a building block with known resources and performance capabilities. It can be surfaced/presented as block or file storage readily… Done correctly, with careful planning and good management tools, abstracting software away from storage hardware can simplify infrastructure and reduce cost of ownership…
  25. 25. Several Ways to Implement  Storage Hypervisor implemented on aCopyright © 2011 by Toigo Partners International LLC. All Rights Reserved. generic server…  Use array mount points already established with server OS…  Aggregate storage capacity as desired into one or more virtual resource pools…  Service I/O from server memory for 2X or more performance bump, regardless of back-end hardware…  Manage capacity, performance and data protection in a unified way…
