TRIAL CLOUD - SuperRackApproached February 2011 with a design for a commodity white box solution to compete with Vblock and vPod.

Designed to run High Density Generic Cloud Workloads as a trial within VMware

Cost per TB primary design consideration but good IOP’s performance important

Architected around Commodity X86 Hardware with our technology partners

Nexenta HA design and scaleout for future with NFS referalls

Classic POD Cloud Design

Hands on Labs Real Workload

5 Nexenta Systems Inc. CONFIDENTIAL

148,103 VM's Created1 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?

6 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 Total928 MB/Sec Reads376 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
