State of the Art SSD Technology

  1. 1. SessionState of the Art – SSD Technology SESSION ABSTRACT Contrasting and comparing enterprise HDD and enterprise SSD technology, examining the pro’s and con’s of each media type and a discussion of how organizations can exploit each technology to effectively improve business performance without risking reliability or currently established SLAs
  2. 2. A Changing Storage Landscape SATA Pure Capacity PlaySLA Tiers FC/SAS Performance Limited Traditional Emerging Storage Memory Vendors Storage Vendors Performance
  3. 3. Expanding Virtualization Drivers What is the key goal behind virtualization for this year? Next year?Reducing the Number of Physical Servers to Fewer Than We Have NowMaintain the Number of Servers We Have, But Keep Up With Application Demand/User Growth Higher Availability Position Ourselves for the Future Disaster Recovery Dynamic Provisioning Cost Savings Improved Manageability and Reporting 2010 Experimentation/Experience 2011 0% 20% 40% 60% 80% 100% Source TheInfoPro (12/27/10): Full Sample. 2010, n=179; 2011, n=178.
  4. 4. Server Virtualization Concerns Which of these is your greatest concern regarding server virtualization for this year? Next year? Performance Under Load Manageability Application Licensing OS Licensing Recoverability Security Reliability Little or No Cost Benefits Compatibilty With OS/Application Chargeback Complexity Using It for Production Applications Learning Curve Cost of Storage VM Licensing Model and Cost Backup and Recovery Stability Learning Curve Knowledge Transfer 2010Interoperability With Other Hypervisors Data Storage Growth 2011 Other 0% 20% 40% 60% 80% 100% Source TheInfoPro (12/27/10): Full Sample. 2010, n=179; 2011, n=179.
  5. 5. #of VMs on a Server That Create a Failure Risk How many VMs will you host on a single physical server before failure risk becomes too great? <5 5-1011-2021-3031-4041-50> 50 0% 20% 40% 60% 80% 100% Source TheInfoPro (12/27/10): Full Sample. n=23.
  6. 6. Today’s Applications Demand Both: High Performance and Consistent SLA Backup, Archive HPC Rich Media Serving OLTP/ Not expecting BI to need ExchangeCapacity Web 2.0 Virtual Desktops / Routine Servers File Serving Cloud Need a better solution Throwaway Trading storage Desk Virtual Dev Servers Spare no expense Performance
