Medusa Labs Test Tools Suite

Medusa Labs Test Tools Suite is leading application-based data testing and signal integrity testing tool enabling developers to identify, locate, and resolve elusive errors through stress testing before products are released to market.

Medusa Labs Test Tools Suite

The Medusa Labs Test Tool (MLTT) Suite 7.4 is the industry’s leading application-based data- and signal-integrity testing solution for companies developing servers, switches, host bus adapters (HBAs), PCIe Interfaces, converged network adapters (CNAs), and other storage equipment for next-generation converged storage networks.

Facilitate design validation, accelerate system bring-up, and simplify quality assurance testing with the MLTT suite for the most comprehensive set of data integrity, benchmarking, and stress-test tools. The MLTT test tools can help uncover and identify data-corruption errors, undesirable device and system data-pattern sensitivities, input/output (I/O) timeouts, I/O losses, and system lockup scenarios. These MLTT capabilities enable development of higher-quality products in less time to reach the market faster. MLTT provides a stable test environment with superior performance using as little CPU overhead as possible. Devices under test (DUT) can run at their optimal rates, giving developers complete—and accurate—visibility into a system’s performance.

Offering advanced storage and TCP application tests, MLTT is a unique commercial analysis and benchmarking tool to support unified storage area network (SAN) and local area network (LAN) applications. Flexible configuration control lets testers create test cases that can simulate TCP applications such as file server, Exchange server, HTTP, Oracle and SIP. MLTT is the ideal tool for combining LAN and SAN tests for next-generation converged-data-center networking.

Solid-State Device (SSD) and NVMe Enhanced Testing

SSD and NVMe devices can present special challenges to qualification and performance testing. Because SSDs tend to start out with a higher level of performance and level out over time, MLTT has a configurable “steady state” detection feature that ensures a stable level of performance prior to benchmark testing. MLTT also includes several erase methods for ATA-, SCSI-, and NVMe-attached devices that can return these devices to a known, factory-fresh state prior to testing.
