Load DynamiX will put your stress to the test

If you’ve never heard of Load DynamiX, that’s probably because until today the start-up was known as SwiftTest. And if you never heard of SwiftTest, that’s probably because until today it only sold its storage validation software directly to storage vendors.

Along with the name change, Load DynamiX today launched a series of infrastructure and application performance validation appliances for IT organizations. The appliances generate massive loads to stress enterprise storage systems, simulate production workloads and validate new devices before putting them into production.

The appliance models include the 10G Base Series with two 10 Gigabit (10 GigE) ports and support for iSCSI and NAS protocol emulation; the 10G Advanced Series with support for NFS 4, SMB 3, HTTP/S, CDMI and OpenStack Swift protocol emulation on top of the Base Series; FC Series with two 8 Gbps Fibre Channel (FC) ports and FC and iSCSI emulation; and the Unified Series with support for two 10 GigE and two FC ports and iSCSI, NFS, SMB 2, FC and SCSI emulation. List prices are $130,000 for the 10G Base, $225,000 for the 10G Advanced, $95,000 for the FC and $180,000 for the Unified appliances.

All of the appliances include Workload Insight Manager, the software the vendor has made available to storage vendors since 2009.

Load DynamiX VP of marketing Len Rosenthal said EMC, Dell, NetApp and Hitachi Data Systems (HDS) use Workload Insight Manager to test their storage arrays.

Rosenthal said each 2u Load DynamiX appliance has the load generation capabilities of 20 servers, and they emulate the I/O profile of applications. He said the appliances are an alternative to using Iometer with a bank of servers. Unlike Iometer, Load DynamiX simulates metadata.

“We’re about understanding changing workloads,” Rosenthal said. “We get people to simulate workloads before going live.”

Rosenthal said used Load DyanmiX to validate a hybrid solid-state drive (SSD) storage array and significantly reduced its cost before putting it into production, and the site fiasco was caused at least in part by lack of load testing before going live.

If you’ve never heard of the fiasco, that’s probably because you’ve been spending too much time trying to get your SAN or NAS up to speed.
