7-1 Configure Software Initiator: Enable Topic 1: iSCSI Storage (GUI & Command Line) Enable the iSCSI initiator, the iSCSI name and alias are automatically filled in Change iSCSI name to match your setup (requires reboot)

7-2 Enter the IP address/Port of each iSCSI target The maximum number of targets is 64 Static Discovery (Using a iSCSI HBA) Dynamic Discovery (Software Initiator or HBA) – Uses “Send Targets” to discover LUNs and all available routes Discovering iSCSI Targets Topic 1: iSCSI Storage (GUI & Command Line) 1

7-3 Viewing and Creating a VMFS datastore Topic 3: VMFS Datastores (GUI & Command Line)

7-4 Add an Extent to your existing VMFS The list of possible extents to add will not include LUNs with an existing VMFS, or RDMs mounted to a VM Topic 3: VMFS Datastores (GUI & Command Line) 5

7-5 Expanding your SAN LUN You can expand a SAN LUN using Mfg. software ESX 3 cannot stretch the VMFS partition on the LUN – Same as adding an extent, results in multiple partitions combined – ESX 4 can perform dynamic expansion of VMFS volumes Topic 3: VMFS Datastores (GUI & Command Line) Process used here: 1.Use SAN software to add another 200 GB to an existing 500 GB LUN 2.Rescan from Storage Adapters shows 700 GB LUN Capacity 3.Properties of existing 500 GB VMFS LUN shows Capacity of 700 GB but Primary Partition of 500 GB 4.Choosing Add Extent allows adding the extra 200 GB extent 5.The final VMFS will be 700 GB with two extents, not one large primary partition 5

Your boss has just announced that all iSCSI connections over the SAN network must be secure. What type of security can you implement with iSCSI SAN on your VMware ESX 3.5 servers? A x authentication with the iSCSI SAN for your VMware ESX 3.5 hosts B. MS-CHAP2 authentication with the iSCSI SAN for your Microsoft hosts C. RSA token authentication with the iSCSI SAN for all hosts D. CHAP authentication with the iSCSI SAN for your VMware ESX 3.5 hosts 5. In VMware ESX 3.5, you attempt to add an NFS datastore to your VMware ESX 3.5 host and you receive an error message. What must be done before you can add an NFS datastore? A. Open the NFS firewall port B. Create a VMkernel port C. Check the box for VMotion D. Open the firewall for the SMB Client 6. A VMware ESX 3.5 host can recognize up to 256 LUNS in a Fibre Channel SAN during boot up. A. True B. False
