Storwize_V7000.fm Draft Document for Review June 27, 2012 9:05 am If the SAN Boot devices are configured with the default reserve policy and path selection algorithm, you must not configure these SAN Boot devices on other AIX servers, since no scsi-2 reserve or scsi-3 persistent reserve is implemented on these SAN Boot devices to prevent access from another AIX server. To find out more about AIX OS installation procedures in multipath SDD SAN Boot environment, refer to the SDD User's Guide, at: http://www-01.IBM.com/support/docview.wss?uid=ssg1S1002675 5.11 More Information Note: For instructions about how to create a logical partition and partition profile, refer to the Creating logical partitions and partition profiles article in PowerVM Virtualization on IBM System p: Introduction and Configuration Fourth Edition, SG24-7940. For more information about the IBM Storwize v7000, refer to Implementing the IBM Storwize V7000, SG24-7938 and the URLs listed below: ► Product site http://www.IBM.com/systems/storage/disk/storwize_v7000/index.html ► Information Center http://publib.boulder.IBM.com/infocenter/storwize/ic/index.jsp ► Configuration Limits and Restrictions http://www.IBM.com/support/docview.wss?uid=ssg1S1003702 ► Techdocs Library http://www.IBM.com/support/techdocs/atsmastr.nsf/Web/Search ► Product Manuals http://www.IBM.com/support/docview.wss?uid=ssg1S7003318 390 SAN Boot Implementation and Best Practices Guide for IBM System Storage
Draft Document for Review June 27, 2012 9:05 am SG247958-iSCSI_DS5000-CL.fm 6 Chapter 6. iSCSI SAN Boot Implementation with IBM system Storage DS5000 Storage area networks (SANs) have been rapidly gaining popularity over traditional client-server configurations due to their ability to efficiently handle data. Typically, SANs require Fibre Channel, a specialized “fabric" or communication backbone. However, Fibre Channel is much more expensive than the standard IP (Internet Protocol) backbone that exists in nearly every enterprise. iSCSI, a new standard for storage networks, encapsulates standard SCSI commands to communicate with disks and transmits them over the existing IP network. Not only is iSCSI seen as a lower cost alternative to Fibre Channel, but is also expected to outperform Fibre Channel as Ethernet speeds jump from 100 Mb/sec to 1 Gb and 10 Gb in the near future. In this chapter, we describe the SAN Boot Implementation using IBM DS5000 series of storage subsystems with iSCSI. © Copyright IBM Corp. 2012. All rights reserved. 391
