GeekOn with Ron #5: Storage Deep Dive with Special Guest

  1. 1. GeekOn Discussion:Understanding Storage and VDI Ron Oglesby @ronoglesby #GeekOn
  2. 2. Special Guest for this GeekOn! Ed Lee, Lead Architect at Tintri Most recently, Ed was Principal Systems Architect at Data Domain, and a key contributor to the first and subsequent releases of Data Domain’s file system. He was responsible for innovations like the BOOST deduplication protocol and replication. Prior to Data Domain, Ed was at Zambeel and Compaq Systems Research Center. He has a Ph.D. from UC Berkeley in Computer Science, where he was an original member of the Berkeley RAID team.Copyright © 2010 Unidesk Corporation. All Rights Reserved. www.unidesk.com
  3. 3. Agenda Why storage became so important to VDI Common desktop disk use characteristics/abilities IO and throughput performance on various types of storage How RAID configurations impact performance Hybrid Arrays
  4. 4. Typical Desktop Profile (workload) From Project Virtual Reality Check Phase III:Copyright © 2010 Unidesk Corporation. All Rights Reserved. www.unidesk.com

  6. 6. Now we need understand disk capabilitiesRotating disk 7.2k, 10K, 15kThe basics of SSD  SLC, eMLC, MLC, TLC, etc  Very High IOPs  Endurance  Expensive per GBCopyright © 2010 Unidesk Corporation. All Rights Reserved. www.unidesk.com
  7. 7. Why is storage so important to VDI? Examples: (Modify for login numbers)  Take those 5 ,10, 15 IOPs per desktops and multiply x 75 or 1000…..  75 Desktops on a single server?  1000 Desktops on a single array? So if you require 750 (raw) IOPs on a server how many rotating disks required? Reliability, Manageability and ScalabilityCopyright © 2010 Unidesk Corporation.

  8. 8. How do controllers and RAID impact IOCacheRAID levelBlock sizeFilesystem  Log structured file systemCopyright © 2010 Unidesk Corporation. All Rights Reserved. www.unidesk.com
  9. 9. Hybrid ArraysBasic explanation of the model  Disk based hybrid-arrays  Flash based hybrid-arraysKey questions to ask of any Hybrid vendorCopyright © 2010 Unidesk Corporation. All Rights Reserved. www.unidesk.com
  10. 10. Storage IO Example for 1,000 VMs
  11. 11. VMware View Planner Lab Results 1,000 VMs4 Dell R720 ESXi hosts  2 x Intel Xeon E5-2690 (2.9Ghz)  256GB RAM  2 x 1 GbE Ethernet adapters  2 x 10 GbE Ethernet adapters Tintri VMstore T540  2.4 TB raw MLC SSD  26 TB raw 5.4K SATA disks
