A manufacturing company wants to centrally manage all their multipath software using Hitachi Global Link Manager (HGLM). Which two types of multipath software are supported? (Choose two.)

Question

Options

• AHDLM
• BVxDMP
• CPowerPath
• DSDD

Explanation

HDLM (A) and VxDMP (B) are the two correct answers.

Hitachi Global Link Manager is designed to centrally manage multipath software on hosts connected to Hitachi storage systems. HDLM (Hitachi Dynamic Link Manager) is Hitachi's own native multipath driver and is the primary software HGLM was built to manage. VxDMP (Veritas Dynamic Multi-Pathing) is also supported, as Hitachi has a longstanding integration partnership with Veritas, allowing HGLM to monitor and manage VxDMP agents on host systems as well.

PowerPath (C) is EMC/Dell's proprietary multipath solution and is not supported by HGLM - it has its own management tools within the Dell ecosystem. SDD (D) is IBM's Subsystem Device Driver, a competing vendor's technology that HGLM has no management capability over.

Memory tip: Think "Hitachi manages Hitachi + Veritas" - HGLM handles its own native driver (HDLM) and its key third-party partner (VxDMP). PowerPath = EMC, SDD = IBM - both are rival ecosystems outside Hitachi's management scope.
