  1. SATA In Enterprise Storage Ron Engelbrecht Vice President and General Manager Engineering and Manufacturing Operations September 21, 2004

  2. Engenio Information Technologies • Leading designer and manufacturer of high performance disk storage technology • 24 years of open storage technology innovation • More than 180 storage patents • Shipped over 212,000 storage systems • Over 18 PB in 2003 alone • Installed footprint of $13.3 billion

  3. Serial ATA – Ready For The Enterprise • SATA’s serial interface and faster mechanism have enabled it to enter the enterprise storage market

  4. Application Access Patterns – IOPS • Random, small-block transfers • OLTP, databases, Exchange • Vast majority of enterprise applications • Drive performance enablers: • Number of drives • More drives equals more IOPS • Seek time, latency, rotational velocity, command queuing

  5. Application Access Patterns – Throughput • Sequential, large-block transfers • Video servers, rich media, seismic processing, HPC • Drive performance enablers: • Data transfer rate, max I/O size, command queuing • Max controller bandwidth typically reached with relatively low number of drives, negating small differences in per drive transfer rates

  6. Classes Of Disk Storage

  7. Enterprise SATA Applications • Secondary storage applications • Disk-to-disk backup / restore • Disaster recovery • Fixed content / reference data • Bandwidth / streaming applications (HPC) • Good throughput at low cost per MB • Entry-level SMB • Low-cost, low I/O requirements

  8. Secondary Storage Applications • Disk-to-disk backup / restore • Shorter backup time / higher application availability • Spinning archive enables faster restores • Improved backup / restore reliability • Fixed content / reference data • Medical imaging, object folders, historical reports • “Nearline” – data previously stored on tape • Disaster recovery • Restoration source of archived information • Hot site storage of “like” data from primary site • Temp work space for short-term processing • Minimal IOPS performance requirements

  9. Primary Storage Applications • Bandwidth / streaming applications • High Performance Computing (HPC), video streaming, media / rich content, oil and gas • Primary requirement: good throughput at low cost per GB • Entry-level SMB • Primary requirement: low-cost • Also has low performance requirement

  10. “How Will You Deploy ATA” D2D Backup Primary Reference / archive Test / temp Disaster recovery Email 40% 20% 20% 40% Current ATA Users All Respondents Baird – Storage and IT Survey III (Q2 ’04)

  11. Application Drive Requirements • FC and SATA will typically be deployed to satisfy very different application requirements • FC – performance requirements • Maximum number of spindles per box/capacity point, spinning at maximum rotations per minute • SATA – cost-per-gigabyte requirements • Minimum number of spindles per box/capacity point, spinning at acceptably fast rotations per minute

  12. Designing An Enterprise-Class SATA System • Redundant pathing for single-ported SATA drives • Dual-active controllers with automatic I/O path failover • Redundant, hot-swappable components • Fully-featured storage management • Online administration and dynamic configuration • Online scalability past initial enclosure • Centralized administration of FC and SATA systems

  13. Engenio SATA Storage Systems • Designed for environments that require lower cost storage, but do not want to give up the availability and functionality achieved with FC-based systems • SATA systems utilize same controllers, enclosures, firmware and management software as enterprise-class FC systems • Unique SATA Interface card provides SATA drives with redundant I/O pathing and FC-like functionality • Robust firmware ensures data protectionand integrity

  14. SATA Solutions In The Field • Customer: Veritas DGC • A leading provider of integrated geophysical, geological and reservoir technologies to the petroleum industry worldwide • Business problem: • Bring more data online to: reduce the time of completion of customer projects; handle more customer projects in parallel; do the same projects more cost effectively. • SATA solution: • Over 400 TB of SATA storage worldwide
