APC iSCSI SATA II Installation Steps for Large Volume Over 2TB, Introduction

E. Installation Steps for Large Volume (Over 2TB)

Introduction:

The iSCSI RAID subsystem is capable of supporting large volumes (>2TB). When connecting controllers to 64bit OS installed host/server, the host/server is inherently capable for large volumes from the 64bit address. On the other side, if the host/server is installed with 32bit OS, user has to change the block size to 1KB, 2KB or 4KB to support volumes up to 4TB, 8TB or 16TB, for the 32bit host/server is not LBA (Logical Block Addressing) 64bit supported. For detail installation steps, please refer to following steps below.

Step 1: Configure target

1.Prepare large capacity hard drivers where the RG/VD capacity will be over 2TB. Follow the steps in Chapter 3 to create a RG/VD. Then attach LUN.

NOTE: If the OS is 64bit, user can set the block size to any available value. If the OS is 32bit, user must change the block size to larger values than 512B. There will be a confirmation pop-up message when VD size is over 2TB.

Choose “OK” for 64bit OS, or choose “Cancel” for 32bit OS. This step will change block size to 4K automatically.

2.Move the mouse pointer to the gray button next to the VD number then click “More information”. Look at block size; 512B for 64bit OS setting, while 4K for 32bit OS setting.

Step 2: Configure host/server

1.Follow the installation guild provided by HBA vendor, install HBA driver properly. For iSCSI models, please install the latest Microsoft iSCSI initiator from the link below.
