Seagate Leadership: SAS for Tiered Storage To better serve your customers, Seagate offers several choices in SAS drives for both Tier 1 and Tier 2 applications. The Seagate® Savvio® 2.5-inch 10K and 15K drives and the Cheetah® 3.5-inch 10K and 15K drives provide mission-critical Tier 1 options while the Barracuda® ES.2 SAS drive is a 3.5-inch 7200-RPM drive designed for Tier 2 nearline applications. Seagate Savvio Drives For mainstream applications, Seagate Savvio 10K and 15K drives are the leading 2.5-inch enterprise drives. Smaller • 70 percent smaller than 3.5-inch drives • More drives in the same space Higher reliability • Industry-leading 1.6M hours MTBF • SAS dual-porting provides redundancy • Backed by a 5-year limited warranty. Faster • 10 percent faster seek times than 3.5-inch 10K • Higher performance per U (more IOPS/U) • Over 30 percent faster sustained transfer rates than previous generation Cooler • Low power consumption equals cooler-running drives • 20 percent less power than 3.5-inch drives • 2.5-inch size enables more airflow to cool processors • Result: lower overall costs 2.5-inch Tier 1 Best-Fit Applications • Mainstream enterprise applications • File and print • Blade servers • Rack and tower servers • Storage arrays Seagate Cheetah Drive The Seagate Cheetah 15K.6 and Cheetah NS drives set a new standard for storage cost-effectiveness with an unprecedented blend of performance, capacity and reliability. Eco-friendly • PowerTrim™ technology provides 62 percent improvement in GBs/watt at idle. Lower cost • Greater areal density means fewer drives, reducing supporting infrastructure, maintenance and space while boosting system reliability Higher performance • Unprecendented performance with a sustained data rate of up to 164 MB/s Better availability • Reduces RAID rebuild times • Minimizes reliability risk exposure • Nonrecoverable error rate improved by 10X 3.5-Inch Tier 1 Best-Fit Applications • Email • Business processing • Transaction processing • Storage area networks • Network attached storage • Internet and e-commerce Seagate Barracuda ES.2 SAS Drives Designed for high-capacity enterprise storage applications in the tier 2 (nearline) storage area, where dollars/GB and GB/watt are a primary concern, the Seagate Barracuda ES.2 SAS drive provides worldleading technology and value. Unbeatable performance - 135% increase over SATA • Full duplex I/O, 7200 RPM • Top performer in sequential read/writes • Improved rotational vibration for use in enterprise cabinetry Superior data integrity • SAS = Full Read and Write Error Correction and Detection (IOECC/IOEDC) vs. SATA with IOECC/ IOEDC on Writes and only IOEDC (Error Detection) on Reads • Dual-port SAS for fail-over and data recovery in shared storage environments Investment protection • Seamless SAS-SATA connectivity (no interposer cards necessary) • Compatible with all existing SCSI software and middleware Eco-Friendly • 12.5 watts operating and 9 watts idle temperature - only 1-watt increase over SATA • PowerTrim™ technology reduces power consumption, heat and energy costs without sacrificing performance Simplicity and continuity • Easy, enterprise-level management with multi-host support - 16:1 = SAS:SATA True enterprise Tier 2 to offload Tier 1 storage • Supports up to 1 TB for storage-hungry applications • Designed for 24x7 operations, 1.2M hours MTBF • Hot-swappable drives and simple four-wire cabling makes serviceability quick and easy • Improved reliability with SAS by eliminating the single point of failure of single-ported SATA drives 3.5-Inch Tier 2 Best-Fit Applications • Maximum-capacity servers • Rich media content storage • R eference and compliance data storage • Video surveillance
