IBM i Hosting IBM i Positioning

Same technology as IBM i hosting AIX, LINUX, and

iSCSI x86 servers

Leverage existing hardware investment

– Create new IBM i 6.1 LPARs using only virtual

hardware (No IOAs, IOPs, disk units, I/O slots

necessary for client partitions), but may also use

physical I/O.

Rapidly deploy new workloads

– Virtual disk created with 1 command or several

clicks in System i Navigator

– New LPAR, virtual resources deployed

dynamically

Create test environments without hardware

provisioning

–

Virtual resources allow new test environments of exact

size to be created, deleted without moving hardware

–

Test new applications, tools, fixes in virtual test LPAR

–

Test the next release in the client partition

PowerVM Active Memory Sharing

PowerVM Active Memory Sharing is an advanced memory

virtualization technology which intelligently flows memory from one

partition to another for increased utilization and flexibility of memory

usage

Memory virtualization enhancement for Power Systems

– Partitions share a pool of memory

– Memory dynamically allocated based on partition’s workload

demands

Extends Power Systems Virtualization Leadership

– Capabilities not provided by Sun and HP virtualization offerings

Designed for partitions with variable memory requirements

– Workloads that peak at different times across the partitions

– Active/inactive environments

– Test and Development environments

– Low average memory requirements

Available with PowerVM Enterprise Edition

– Supports AIX 6.1, i 6.1, and SUSE Linux Enterprise Server 11

– Partitions must use VIOS and shared processors

– POWER6 processor-based systems

Such information is not intended as a definitive statement of a commitment to specific levels of performance, function or delivery schedules with respect to any future products. Such commitments are only made in IBM product announcements. The information is presented here to communicate IBM's current investment and development activities as a good faith effort to help with our customers' future planning.

Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput or performance improvements equivalent to the ratios stated here.
