FCP Full fabric connectivity

attachability means that customers have more choices for new storage solutions, or may have the ability to use existing storage devices, thus helping to leverage exist- ing investments and lower total cost of ownership for their Linux implementation.

and in the Planning section go to z890/z990 I/O Connec-

resources and infrastructure. Further savings may be real- ized in the reduction of the number of fi ber optic cabling and director ports.

When confi gured as FCP CHPID type, the z890 FICON Express features support the industry standard interface for Storage Area Network (SAN) managment tools.

tion information.

The support for FCP channels is for Linux and z/VM 4.3 and later. Linux may be the native operating system on the zSeries server (note z890 runs LPAR mode only), or it can be in LPAR mode or, operating as a guest under z/VM 4.3 or later. The z890 provides support for IPL of Linux guest images from appropriate FCP attached devices.

Now, z/VM V5.1, support for SCSI FCP disks enables the deployment of a Linux server farm running under VM con-

figured only with SCSI disks. With this support you can install, IPL, and operate z/VM from SCSI disks.

The 2 Gbps capability on the FICON Express channel cards means that 2 Gbps link data rates are available for FCP channels as well.

FCP Full fabric connectivity

FCP full fabric support means that any number of (single vendor) FCP directors/ switches can be placed between the server and FCP/ SCSI device thereby allowing many “hops” through a storage network for I/O connectivity. This support along with 2 Gbps link capability is being deliv- ered together with IBM and directors from IBM, CNT, and McDATA. FCP full fabric connectivity enables multiple FCP switches/ directors on a fabric to share links and there- fore provide improved utilization of inter-site connected

Preview - FCP LUN Access Control

IBM zSeries is previewing Fibre Channel Protocol (FCP) Logical Unit Number (LUN) Access Control which is designed to provide host-based control of access to storage controllers and their devices as identifi ed by their logical unit numbers (LUNs). It will allow read-only sharing of FCP SCSI devices among multiple operating system images.

If a host channel is shared among multiple operating system images, the access control mechanism would pro- vide for either none or all of these images to have access to a particular storage controller or device (logical unit).

FCP LUN Access Control will allow you to defi ne, via an access control table, individual access rights to storage controller ports and devices for each operating system
