Introduction

I have been working as a UNIX administrator since 1992, starting with AIX and moving to Solaris and Linux. I have been using Legato (now EMC) Networker off and on since 1996. I have only been directly responsible for Networker the last four years.

We are currently running Networker 7.3.3 on a Sun T2000 with 16 threads and 16 GB of memory. We are trunking two of the copper gigabit Ethernet adapters. There are three QLogic 2462 HBA’s in this system: two ports are connected to SAN disk, two ports are connected to two 9509 2GB FC switches (connected to the tape library) , and two ports are connected to two 9513 4GB FC switches (connected to two VTL’s.

We have 139 Windows clients, 44 Linux clients, 118 Solaris clients and 13 AIX clients. We also have 6 clusters, 6 NDMP and 3 Exchange servers. We also have two COPAN VTL’s (more on this later). We also have one storage node and 25 dedicated storage nodes. We have a Quantum (ADIC) i2000 with 9 LTO-2’s, 11 LTO-3’s and 16 LTO-4’s. Quite a varied installation!
