  • 1. Storage media solution "including pricing as a factor" Tony Roug Rougs.com LLC Storage Technology Consulting August 15, 2013
  • 2. Where does pricing fit? • Storage decision are driven by – Capacity – Performance – Price • In a world of many technologies and usage models – what's a simple visualization of the above – propose best price tradeoff for single server configs Rougs.com LLC Copyright HDDSSDPCIe SSDDDR or or or or What's the low cost for a Performance/Capacity requirement assumes a "commodity" model for storage hardware
  • 3. Configuration • Server configuration – Basic SuperMicro 1U and 2U rack 23.5" server – processor/board: Xeon E5 C600 Chipset – Single and Dual – drive slots: 1U - 10, 2U – 24, assume possible for either 2.5 or 3.5 (i.e. HDDs.) – PCIe slots: 1U – 2, 2U – 4, only consider half height, half width – DDR: up to 1TB per server – All configurations forced to single server – Servers Direct Pricing • SATA/SAS HDDs – Seagate 15K/10K and 7.2K SATA – Servers Direct pricing – IOPS based on rotational speed • SATA SSDs: – SATA SSDs (Intel) – Amazon and NewEgg pricing – Spec sheet 4K random performance • PCIe SSD: – Intel 910, Amazon Pricing – No Fusion because no public price or performance info • DDR DRAM: – Kinston – Servers Direct Pricing – Spec Sheet performance • Notes/Assumptions – IOPS Performance scales linearly as drives are added – No extra drives for reliability or availability Rougs.com LLC Copyright

  • 12. Summary • For a simple study on spec price/performance • Commercial SATA SSDs have significantly improved in 3 years • Can cover most of the common usage cases • For typical usage models, performance of SATA SSD seems largely good enough • For typical usage models, SATA SSD seem to be the lowest power for almost all usage models
