IBM Solid State in eX5 servers

  1. 1. System x® and BladeCenter® Key uses for SSDs in servers today 1. To replace spinning boot disks to improve application performance, power consumption, reliability, etc. Boot disks – Low cost SSD - better reliability, good read performance High performance databases, web/e-Mail servers – High performance SSDs can replace many HDDs Note: All Flash/SSD is not created equal! Consumer flash technology (USB memory sticks, MP3s) is cheap but lacks enterprise class durability, reliability, data protection – write cache protection, wear data leveling, etc. 2. To replace spinning disks in High IOPs storage systems for improved performance of high transaction applications Each SSD can deliver the same IOPs performance as dozens of traditional spinning disks Reduction in storage acquisition cost and lower ongoing power & cooling cost Improved application performance for local database and IOPs constrained environments 3. As a fast virtual memory paging device to reduce need for expensive main memory DIMMs Possible reduction in server acquisition costs and lowering ongoing power and cooling costs. Big reduction in server cost with small reduction in application performance. Results are application/workload dependent More usages will come as enterprise SSDs continue to improve in price and performance… © 2010 IBM Corporation 1
  2. 2. IBM Modular and Blade Systems IBM 50GB High IOPS SSD for System x Servers and Blades 4K Multi-Threaded Random Read/Write Workload High IO Performance (67% Read, 33% Writes, 100% Random) – Up to 8X IOPS more than HDD 3000 – Media streaming, surveillance, file copy, logging, 2600 backup/recovery, business intelligence apps 2500 Lower cost IOPS Performance than HDD 2000 – Lower $/IOPS, less power and smaller footprint IOps 1500 required to reach performance target 1000 Superior Uptime – 3X the availability of mechanical drives with 500 291 372 RAID-1 – no moving parts to fail 41 0 – Enterprise wear leveling to extend life even 4K further Transfer Size (bytes) Flexible Deployment With Full OS Support 146GB SAS Drive Savio 10K.2 (FW B522) 73GB SAS Drive Savio 15K.2 (FW B612) 32GB SATA Flash SSD 50GB MACH8 IOPS SSD – Traditional HDD form factor offering – Supported in servers or EXP3000 disk IBM High IOPS SSD enclosures Name Part Number Support IBM 50GB SATA 3.5" HS High IOPS SSD 43W7698 EXP3000 with MR10M IBM 50GB SATA 2.5" SFF NHS High IOPS SSD 43W7706 HS21XM, LS22, LS42 IBM 50GB SATA 2.5" SFF Slim-HS High IOPS SSD 43W7714 HS22, 3550-M2, x3650-M2 50GB SATA 2.5" Slim HS High IOPS SSD IBM 50GB SATA 2.5" SFF HS High IOPS SSD 43W7722 3850-M2 & 3950-M2 Available today 2 © 2010 IBM Corporation
  3. 3. IBM Modular and Blade Systems High Performance SSDs for DS5000/8000 & SVC STEC Zeus-IOPS FC & SAS SSDs – 73, 146, 300, and 600GB capacities – Recognized leader for external storage – Meets IBM’s enterprise drive requirements SSD benefits – Increased small-block I/O performance – up to 80000 IOPs each – Up to 350MB/s for streaming applications – Lower power usage – up to 80% decrease – Dramatic reduction in system space for equivalent I/O 3 © 2010 IBM Corporation
  4. 4. System x® and BladeCenter® High IOPS SSD PCIe Adapters Superior solution to enterprise disk drives for applications sustaining high operations per second – e.g. database, data warehouse, stream analytics Based on fast growing NAND flash technology Standard PCIe form factor supports rack/tower servers and blades (via PEU/BPE3) Available in 160GB and 320GB capacities (640GB coming soon) Typically higher IOPs and MB/s performance than SATA/SAS/FC 160GB SLC 160GB SLC random sequential attached SSDs (IBM measured) (IBM measured) Must be mirrored via software to 4K Read 108,031 IOPS 128,509 IOPS provide data protection against an 32K Read 744 MBps 754 MBps adapter failure 32K Write 492 MBps 635 MBps Typically lowest cost per IOP vs. traditional SSDs © 2010 IBM Corporation 4
  5. 5. System x® and BladeCenter® Comparing SSD form factor – disk drive vs. PCI-E Disk drive: PCIe adapter: Low cost SSDs are good for boot - Adapter looks like a single disk to can exceed HDD performance on the OS and application. reads, though slow on writes Can provide higher IOPs than High performance SSDs are 100- SSD due to higher bandwidth of 1000x faster in random workloads PCIe vs. SAS, SATA, and FC than HDDs, but cost 10-100x more per GB Mirror 2 adapters using software for fault tolerance - can be costly Can be used like HDDs in RAID arrays for fault tolerance and/or data Direct sharing of the adapter/data sharing by >1 server typically not possible. RAID adapters/controllers can limit performance when many SSDs are used per adapter © 2010 IBM Corporation 5
