What's new for V5R4

For V5R4, Windows environment on iSeries has several new functions:

• Support for integrating xSeries® and IBM® BladeCenter™ systems with the iSeries™ server via the iSCSI host bus adapters (iSCSI HBAs) is provided. This server integration technology complements the existing Integrated xSeries Server and Integrated xSeries Adapter technologies. Support is provided for servers connected by a scalable Gigabit Ethernet network using the iSCSI protocol and supported adapters in both the iSeries and xSeries servers. For information about how the iSCSI technology is used to integrate IBM xSeries and BladeCenter systems with the iSeries server, see Concepts. For information about how to manage and configure iSCSI attached servers, see Administer connections to iSCSI attached servers and Administer integrated Windows servers.
• The product IBM iSeries Integration for Windows Server (5722-WSV) has been repackaged as i5/OS™ Integrated Server Support (5722-SS1 option 29).
  Note:
  When you upgrade from a prior release to i5/OS V5R4, product 5722-WSV is automatically removed and product 5722-SS1 option 29 is installed in its place.
• Increased storage capacity for iSCSI attached Windows servers. Up to 64 disk drives (network server storage spaces) can be attached to an iSCSI attached Windows server, allowing over 60 TB of disk storage per server.
• Support for extending the size of a disk drive (network server storage space) is added. See Expand a disk drive.
• Support for Windows Server 2003 Volume Shadow Copy Service is added, which can be used by backup applications that run on Windows. This allows data for applications that support the Volume Shadow Copy Service to be backed up without stopping the application, which improves application availability. See Back up and recover integrated Windows servers.
• Additional iSeries Navigator GUI support, including support for managing iSCSI attached servers, managing integrated Linux® and AIX® servers, and configuring virtual Ethernet ports for integrated servers.
• Support for the 200 MHz and 333MHz IBM Integrated PC Server for AS/400® (IPCS) and IBM Integrated Netfinity® Server for AS/400 (INS) is withdrawn. The withdrawn IPCS and INS hardware resource types are 6617 and 2850 with feature codes 2854, 2857, 2865, 2866, 6617 and 6618. Since IPCS and INS servers were the only integrated server types that provided host LAN support (sharing LAN adapters between i5/OS and Windows), the host LAN function has also been withdrawn.
• Information previously in this document related to Windows NT® 4.0 servers (which are no longer supported as of V5R3), IPCS or INS hardware (types 6617 and 2850), shared network adapters (host LAN), and considerations for servers installed before V4R5 has been removed from this document. For information related to these topics, refer to the Windows environment on iSeries topic in the V5R3 iSeries Information Center.
