  75. 75. © Copyright IBM Corporation 2009<br />What is iSCSI?<br />iSCSI: Internet SCSI (Small Computer System Interface), SCSI commands sent across a network in TCP/IP packets. It was developed as a storage networking standard for linking data storage facilities<br />Initiator: System making the iSCSI requests for data<br />Target: System receiving the iSCSI requests for data<br />
  76. 76. © Copyright IBM Corporation 2009<br />iSCSI expansion card overview<br />The iSCSI expansion card offers a connection to an iSCSI storage device, via iSCSI host connections, to leverage the available standard Ethernet infrastructure to offer storage area network (SAN) solutions<br />Blade Server<br />iSCSI Storage Device<br />Via TCP<br />

  83. 83. © Copyright IBM Corporation 2009<br />Benefits to booting from SAN<br />Improving disaster tolerance If a server becomes faulty, unavailable or compromised, it can be swapped out for a new server with the same configuration, without having to: <br />Reconstruct the booting, operating and application environments for the new machine when it is most urgently needed. <br />Swap out hard drives, reconfigure arrays, and restore data and applications from backup. <br />The ability to replace and add servers in minutes provides a significant return on investment (ROI) by preventing lengthy downtime of core servers. <br />Enabling centralized administration <br />Reducing TCO through diskless servers <br />Using high availability (HA) storage ensuring business continuance<br />
  84. 84. © Copyright IBM Corporation 2009<br />Implementation considerations of booting from SAN<br />The server must have an FC HBA equipped with a boot BIOS that can support booting from the storage device attached to the SAN<br />Typically the host needs to have a boot order of CD-ROM, diskette, and then drive 0 <br />The SAN must be installed and configured, and the storage visible to the host<br />The storage system must have at least one available LUN for booting the server(s)<br />The storage must be configured to allow the server exclusive access to the LUN; access is typically assigned via the FC HBA’s WorldWide Port Name (WWPN) on the storage<br />To minimize data interruptions between hosts, it is best to keep hosts separated from each other by way of zoning to minimize the Registered State Change Notification (RSCN) interruptions<br />
  85. 85. © Copyright IBM Corporation 2009<br />Booting from SAN: Creating the LUNs<br />Create an array<br />Create a logical drive (LUN) <br />From the blade, broadcast the WWPN<br />Map the LUN to the host via the WWPN<br />Assign the Boot LUN to HBA Port A<br />Install the operating system<br />9 GB Logical Drive<br />18 GB<br />18 GB<br />18 GB<br />Array A (RAID 5)<br />

Select Configuration Settings and Host Adapter Settings.</li></li></ul><li>© Copyright IBM Corporation 2009<br />Broadcasting the world wide name (WWN)<br />In order for the storage device to see the HBA ports, you need to open the port by doing a Scan Fibre Devices. Do this for both ports.<br />
  91. 91. © Copyright IBM Corporation 2009<br />Mapping the logical drive to the WWN<br />
  92. 92. © Copyright IBM Corporation 2009<br />Assign the boot LUN to an HBA port <br />We want to assign the boot LUN to port B also, but we will disable this path during the initial OS installation<br />
  93. 93. © Copyright IBM Corporation 2009<br />Installing the operating system<br />You must use the Fibre card Driver diskette during the installation phase (press F6 for boot disk during install)<br />During the POST sequence notice the following text:Drive letter C: is moved to the Drive letter D:<br /> Loop ID 129,0 is installed as Drive C:<br />This indicates that the blade is now booting from the LUN 0 associated to the first HBA adapter<br />
