HDS 2000-series AMS Storage Arrays (3)

Day 3 of the TCI1535 class.  Day 1 summary here, Day 2 is here.All of the day spent working with SNM2, GUI and CLI. Extensive lab work, good stuff!SNM2 is client-server. Specs included for server, Windows-only, no Solaris option. 2GHz CPU/2GB RAM recommended. Client reuires JRE 1.6.0 or higher. "password protection" from thunder/ams is being superseded by server-based "account authentication" move is more towards HDvM-style system. Installer needs to know IP address of management PC (SNM2 server) during wizard. GUI is a LOT like HDvM! Also has extensive on-line help. Initial setup procedures are a wizard. Alerts, ports, spares, WWNs, you get the idea.License keys must be installed as usual.Basic install lab activity--scheduled 60minutes, took about 90 for the three groups to complete. Lots of questions, no real problems. Looks like SNM2 works as described.LU Wizard is MUCH improved over SNM! Does the same tasks as SNM but interface is much cleaner.Host Groups now allow for heterogeneous Multi-Host Connections. LUN Manager section of SNM2 manages access. LUSE is changing. Existing material (and SNM2) still describes, but concept is changing, as is name of feature.Software Features - use "Advanced Settings" section of SNM2 to get to these. Must do custom config of Java 1.6.x to make work. Procedure is well-explained. SNM2 kicks you out of Advanced Settings after 30min of inactivity.Cache Partition Manager - no changes from earlier AMS. Copy-On-Write snapshot requires a re-boot of array--2000s support up to 32 snapshots, array must re-configure cache and carve out a lot of control memory for VVOL devices. Richard really rips on snapshots on modular. I'll be revising my notes on AMS2500-vs-USPVM based on his opinions on extent COW is a cash hog.
