3. Introduction As IT professionals we apply technology solutions to business problems. We adapt to the technologies at hand and utilize them in the most efficient, cost effective manner to fulfill the needs of our customers. Some technologies have allowed us to deliver the complete power of a system to the end user and other technologies have not taken advantage of the available resources.

Classes of Servers Three classes of Servers Basic Server Inexpensive Not expandable Not redundant hardware Mid Range Server Somewhat Expensive Limited expandability Contains redundant components UPS power High End Server Is Very Expensive Fully expandable Multiple computer for clustering High End Server Is Very Expensive Fully expandable Multiple computer for clustering Cost and Maintenance LLNL-PRES-413167

13. Server Availability Three tiers of availability Basic Server Can be down 1 to 2 days Not part of redundant architecture Multiple single point of failure Is backed up Mid Range Server Can only be down ½ day or less Has some Redundancy UPS power Is backed up and has a recovery plan Critical Server Can only be down 1 hour or less Contains multiple redundant components Is usually part of a cluster Is backed up and has a recovery plan More Available LLNL-PRES-413167

LLNL Server Ratios Physical ServerSmall SizeTotal VMs 2 ESX Servers1835 Physical ServerMid SizeTotal VMs 2 ESX Servers1428 Physical ServerSmall SizeTotal VMs 2 ESX Servers3570 Physical ServerMid SizeTotal VMs 2 ESX Servers2856 Proposed Ratio – The original virtualization proposal suggested that per ESX server there could be 18 low/small utilization virtual servers and 14 mid utilization virtual servers Actual Projected Ratio – The actual ratio shows the original proposal to be too conservative. The numbers reflected below are estimates based on current ESX server utilization numbers and reflect a more accurate picture of the hardware utilization. LLNL-PRES-413167

33. LLNL Server Expansion Server Farm ESX Server Virtual Machines ESX Server Network Storage ESX Server ESX Server Server expansion will allow a higher utilization of each one of the ESX servers due to higher ratio of failover algorithms LLNL-PRES-413167
