Dell EqualLogic FS7500 – Unified block and file storage for virtual workloads

Virtual Workload Description

To ensure that we simulated a real life situation for our performance measurement, we chose to run a

virtual workload mix based on a set of typical datacenter workloads including business applications as

well as operations associated with managing the virtual environment. We used workloads suggested by

VMware's VMmark 2 benchmark, as these workloads are representative of popular applications

commonly run in the datacenter. However, individual loads were modified to saturate the storage

system in the test environment while making sure that other subsystems were not becoming a

bottleneck. We used a mix of the following three application workloads:

Mail server operations using Microsoft Exchange

The workload emulates 1000 heavy profile users with a fixed mailbox size and measures the transaction

capability of the email server based on number of completed email transactions.

Social networking operations using Olio, Web 2.0 based applications

The Olio workload is fixed at 400 concurrent users and the completed operations per minute reflect its

performance.

E-commerce transactional operations using DVDstore and MySQL databases

The workload simulates customer shopping activity including browsing catalogs, shopping, and

checkout with number of transactions per minutes reflecting the performance achieved.

In addition to the above application workloads, in parallel we also ran nominal virtualization

infrastructure activities like vMotion, Storage vMotion and VM creation in each run. For each underlying

benchmark, the application transaction counts were gathered at an acceptable quality of service (QoS)

represented by a maximum allowable transaction response time

storage environment was near saturation with sufficient headroom in CPU, memory, and network

resources. The table below shows a consolidated view of the workload mix.

These response time values were measured at the application using Windows PerfMon.
