1 Topics Networking Concepts Storage Concepts Presentation by Anand Mewalal Vmware VI3 Concepts On networking and Storage

2 Networking Concepts There are 3 types of Port :Service Console Port Virtual Machine Port VMKernal port Virtual Switch : vSwitch detects which virtual machines are logically connected to each of its virtual ports and uses that information to forward traffic to the correct virtual machines. Port Group: Specifies port configuration options such as bandwidth limitations and VLAN tagging policies for each member port. Labeled networks are properly configured only when all port groups using the same network label are able to see the same broadcast traffic. vNic Mac Address:An Algorithm is run which takes a combination of Network Adapter OUI (organizationally unique Identifier) x Vmware UUID (Universally Unique Identifier) Max No of vSwitches on a single host – 248 Max no of logical port of a single switch – 1016 Max no of port groups on a single host – 512

3 Creating a Virtual Switch Click the Configuration tab, and click Networking. On the right side of the screen, click Add Networking.

11 Design a network configuration for an ESX server based on a set of requirements You are an administrator in charge of configuring an ESX server in your company's production environment. Fill in the virtual switch layer, indicating port groups and thier policies, and the physical connection between the server's physical NIC's and the external switches. Details of the networking environment include VM's and Application: Web based applications implemented using 3 VM's arranged as follows: VM1 and VM2 - the web servers - NAT Clients of VM3 VM3 - the front end for the web server - act as a NAT router for the backend VM's VM4, a test box - used to test intrusion detection systems and virus protection software, among other applications IP based Storage - A NAS, used to hold running vm for the test VM's only (storage for the production VM's is provided by SAN) Physical NIC's : There are 4 physical adapters, 1 x 100MBPS and 3 Gig Ethernet cards Ethernet networks: There are 2 physical switches and 4 external LAN's, each named to indicate its purpose. A single physical switch is configured to handle traffic for 3 networks, which are implemented as VLAN's. One Physical switch is dedicated to the management LAN that by company policy must be physially separated from all networks. The management LAN is used by Virtuial centre.

12 Storage Concepts ESX Server supports the following types of storage devices: Local – Stores files locally on an internal or external SCSI device. Fibre Channel – Stores files remotely on a Storage Area Network (SAN). Requires Fibre Channel adapters. iSCSI (hardware initiated) – Stores files on remote iSCSI storage devices. Files are accessed over TCP/IP network using hardware-based iSCSI HBAs. It Uses CHAP authentication. iSCSI (software initiated) – Stores files on remote iSCSI storage devices. Files are accessed over TCP/IP network using software-based iSCSI code in the VMkernel. Network file system (NFS) – Stores files on remote file servers. Files are accessed over TCP/IP network using the NFS protocol. Requires a standard network adapter for network connectivity.

15 SAN STORAGE - Multipathing

16 Max LUNs per host – 256 LUNs Max virtual HBA per VM – 4 HBA Max targets per HBA – 15 Max target per VM – 60 SAN – WWPN – vmhba1:3:0:1 adapter, target, LUN, and partition ISCSI – IQN No: iqn com.mycompany:myserver iqn.. : You can have Fibre Channel and Iscsi HBA in the same ESX server but not supported to access the same LUN.
