CONFIDENTIAL 148,103 VM's Created 1 VM created every 1.215 Seconds 2 Hours Lab time on average per attendee 50 Hours of Lab time during the show 12,388 Lab Hours sat in total By the way – we also destroy them at the end of each lab…..!!!! 13,415 Labs Taken by attendees 5042 Attendees took the Labs 487 Simultaneous Lab seats an hour Nested VM’s workload – Highly latency sensitive Each lab deploys between 10-25 VM’s per lab seat Completely Random based choice of labs – No way to determine and precache Each VM up to 26GB in size
  • How did we stack up? Nexenta Systems Inc. CONFIDENTIAL 7.9 Billion IOPs server from 4 Heads during the labs 3 Billion IOPs server from 1 Controller Peak controller load 154K 4K NFS ops at sub 1 ms latency Highest Bandwidth on a Single head (Average I/O 16k) 1,305 MB/sec Total 928 MB/Sec Reads 376 MB/Sec Writes Less than 2 ms latency 38,590 NFS 16K NFS ops Peak load on a single controller Ran 4 of the 8 Workloads for the duration of VMworld RAM failure in a head triggers HA failover HA works faultlessly and Controller 3 runs the workload of 2 controllers for 6 hours seemlessly. Cost $ 325,000
