Chapter 3. Virtualization 85

Draft Document for Review September 2, 2008 5:05 pm 4405ch03 Virtualization.fm

At the time of writing, virtual SCSI supports Fibre Channel, parallel SCSI, iSCSI, SAS, SCSI

RAID devices and optical devices, including DVD-RAM and DVD-ROM. Other protocols such

as SSA and tape devices are not supported.

For more information about the specific storage devices supported for Virtual I/O Server, see:

http://www14.software.ibm.com/webapp/set2/sas/f/vios/documentation/datasheet.html

Virtual I/O Server function

Virtual I/O Server includes a number of features, including monitoring solutions:

򐂰 Support for Live Partition Mobility on POWER6 processor-based systems with the

PowerVM Enterprise Edition. More information about Live Partition Mobility can be found

on 3.3.4, “PowerVM Live Partition Mobility” on page 87.

򐂰 Support for virtual SCSI devices backed by a file. These are then accessed as standard

SCSI-compliant LUNs.

򐂰 Virtual I/O Server Expansion Pack with additional security functions like Kerberos

(Network Authentication Service for users and Client and Server Applications), SNMP v3

(Simple Network Management Protocol) and LDAP (Lightweight Directory Access

Protocol client functionality).

򐂰 System Planning Tool (SPT) and Workload Estimator are designed to ease the

deployment of a virtualized infrastructure. More on the System Planning Tool in section

3.4, “System Planning Tool” on page 91.

򐂰 IBM Systems Director and a number of preinstalled Tivoli® agents are included like Tivoli

Identity Manager (TIM) in order to allow easy integration into an existing Tivoli Systems

Management infrastructure, and Tivoli Application Dependency Discovery Manager

(ADDM) which creates and maintains automatically application infrastructure maps

including dependencies, change histories and deep configuration values.

򐂰 vSCSI eRAS

򐂰 Additional Command Line Interface (CLI) statistics in svmon, vmstat, fcstat and topas

򐂰 Monitoring solutions to help manage and monitor the Virtual I/O Server and shared

resources. New commands and views provide additional metrics for memory, paging,

processes, Fibre Channel HBA statistics and virtualization.

For more information on the Virtual I/O Server and its implementation, refer to PowerVM

virtualization on IBM System p, Introduction and Configuration, SG24-7940.

3.3.3 PowerVM Lx86

The IBM PowerVM Lx86 feature creates a virtual x86 Linux application environment on

POWER processor-based systems, so most 32-bit x86 Linux applications can run without

requiring clients or ISVs to recompile the code. This brings new benefits to organizations who

want the reliability and flexibility of consolidating (through virtualization) on Power Systems

and use applications that have not yet been ported to the platform.

PowerVM Lx86 dynamically translates x86 instructions to Power Architecture instructions,

operating much like the Just-in-time compiler (JIT) in a Java™ system. The technology

creates an environment in which the applications being translated run on the new target

platform, in this case Linux on POWER. This environment encapsulates the application and

runtime libraries and runs them on the Linux on POWER operating system kernel. These

applications can be run side by side with POWER native applications on a single system

image and do not require a separate partition.
