New with Virtualization

VM Placement• Goal: Determine the number of physical servers required

• How to do VM Placement?- Manual placement using the rules in the docwiki- Use VM Placement Tool (VMPT)

Logical Processors

CPU Resources – Physical Core

Consider the number of PHYSICAL cores on the server

Core 1 Core 2

Core 3 Core 4

Core 5 Core 6

Do not consider the number of LOGICAL cores obtained through Hyper-threading

CPU Cores

Core 1 Core 2

Core 3 Core 4

Core 5 Core 6

Dual sockets, 6 cores per socket

CPU Resources - Mapping

No oversubscription: The number of vCPUs can’t exceed the number of physical cores

Mapping: One vCPU = One physical core

vCPUUCM-PUB UCM-SUB1 IM&P-1 CER-1 CCX-1

CPU Resources – Unity Connection

With Unity Connection only:Reserve a spare core for the ESXi scheduler

Other Hardware Resources

◆ Memory▪ No Oversubscription▪ Reserve RAM for ESXi scheduler

• ESXi 5.1 or earlier: 2 GB• ESXi 5.5: 4 GB

◆ Storage▪ Ensure enough storage space is available▪ Thick vs. Thin provisioning

• TRC with DAS: Thick provisioning required• Specs-Based or SAN: Thick provisioning recommended, Thin provisioning allowed

Co-residency with 3rd party applications

More info in the docwiki:http://docwiki.cisco.com/wiki/Unified_Communications_Virtualization_Sizing_Guidelines

• The co-residency rules and categories apply to TRC and Specs-Based• Number and Type of 3rd party co-resident applications limited with Cisco

Collaboration virtualization SW OEMs (Cisco UC Virt. Hypervisor/Foundation, default ship with BE6000/BE7000)

• TAC TechNote: http://www.cisco.com/en/US/products/ps6884/products_tech_note09186a0080bbd913.shtml

• UC on UCS rules also imposed on 3rd party VMs (e.g. no Oversubscription allowed for 3rd party apps)

VM Placement Tool

• Visual VM placement tool

• Greatly simplifies VM Placement

• Most co-residency rules are implemented

Virtual Machine Placement Tool (VMPT): http://www.cisco.com/go/vmpt

VM Placement Tool

VM Placement – Example with 5000 users

Best Practices• Spread VMs across different

nodes to minimize failure impact.

• Provide spare capacity for future growth, server maintenance, or Collaboration application upgrades possibly requiring more resources.

Storage Performance Design

No IOPS calculation needed

• Use TRC as reference• Or calculate IOPS

Networking Considerations with UCS C-series• In general, use all ports available… Or

Calculate Bandwidth requirements for each VM– Bandwidth Formulas available in the Design Guides and SRND.– Only account for traffic in/out of the host (not within host)– Consider traffic streams that carry media, especially Video

• Plan for upstream switch redundancy.With redundancy, need 2x number of ports.

VMware vSphere Release Compatibility

• ESXi release support varies with UC application (many apps do not support ESXi 5.5)

• ESXi Updates (e.g. U1, U2, etc…) implicitly supported unless specified otherwise

• For the exact release of Cisco Collaboration application or ESXi, refer to the docwiki

Summary

Application Design

VM Placement

▪ Perform the Application Design as usual – Deployment Model, High Availability, VM Config, Number of VMs…

▪ VM Placement– Select type of platforms (TRC vs. Specs-based, B vs. C,…)– VM placement: Sizing and Co-residency– Storage, Networking, VMware considerations

▪ Plan how to install/migrate
