z/VM vs. Distributed Hypervisor Matchup: z/VM Holds the Title
Hear from Reed Mullen, IBM's lead product planner for z/VM, to learn why so many are re-discovering the value of z/VM. The content of this webinar is designed to give attendees an understanding of the technology advantages to running Linux under z/VM.More
Hear from Reed Mullen, IBM's lead product planner for z/VM, to learn why so many are re-discovering the value of z/VM. The content of this webinar is designed to give attendees an understanding of the technology advantages to running Linux under z/VM. Reed will focus on the following two major themes:
Business Drivers of Infrastructure Simplification
It's likely you've heard a virtualization pitch before. What makes z/VM on the System z platform different? This section will detail the IBM Mainframe qualities of service, systems management efficiencies gained with z/VM, and overviews of customer deployments.
System z Technology Exploitation in z/VM Red Hat Enterprise Linux running on z/VM exploits several features of both the hardware and underlying hypervisor, many of which are not available on other platforms. Reed will detail the following, from a technical level:
- How CPU sharing works
- How I/O is shared across multiple zones on IBM System z
- Resource over commitment
- VMRM Cooperative Memory Management (VMRM-CMM)
- Discontiguous Saved Segments (DCSS), which allows z/VM to share a single, real memory location among multiple virtual machines
- VDISK configurations, which allows for simulating a storage device using real memory. VDISKs are especially applicable for workload which has high swap rates.
- N_Port ID Virtualization (NPIV) support
- Parallel Access Volume (PAV), and HyperPAV, which allows multiple concurrent I/O operations to the same disk by multiple virtual machines
- Virtual networking on System z, covering VLAN, VSWITCH, and Link Aggregation technology
- Coordinated near-continuous availability and DR solution for z/OS, Linux, and z/VM using GDPS technology.
