VM Placement 2 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) Resources - Docwiki: http://www.cisco.com/go/uc-virtualized - VM Placement Tool (VMPT): http://www.cisco.com/go/vmpt tuali r i V h t wi New zation

CPU Resources Physical Core Dual sockets, 6 cores per socket Core 1 Core 2 Core 1 Core 2 Core 3 Core 4 Core 3 Core 4 Core 5 Core 6 Core 5 Core 6 Consider the number of PHYSICAL cores on the server CPU Cores Do not consider the number of LOGICAL cores obtained through Hyperthreading Logical Processors

CPU Resources - Mapping Mapping: One vcpu = One physical core No oversubscription: The number of vcpus can t exceed the number of physical cores vcpu UCM-PUB UCM-SUB1 IM&P-1 Cores 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: Mixing Applications Limited (includes no co-residency) Specific Cisco UC Specific Cisco UC Examples: CWMS CCE Logger 8.x UC with UC Only Cisco UC Cisco UC Examples: CUCM 8.6(1)IM&P 8.5(x)CUC 8.5(1)CCX 8.0 CCE Logger 9.x Full Cisco UC+ Non-UC/3rd party Cisco UC Examples: CUCM 8.6(2)+ IM&P 8.6(1)+ CUC 8.6(2)+ CCX 8.5+ CCE 10+ 3rd Party/Non-UC (e.g. Nexus 1000v, vcenter)

Co-residency with 3rd party applications UC on UCS rules also imposed on 3rd party VMs (e.g. no Oversubscription allowed for 3rd party apps) 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 More info in the docwiki: http://docwiki.cisco.com/wiki/unified_communications_virtualization_sizing_guidelines

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.

AGENDA Overview Platforms How To Design Other Design Considerations: Storage and Network Considerations VMware features support How To Deploy

Storage Array Requirements UCS B-series TRC Storage Vendor Specs-Based Any Vendor compatible with Server and VMware Storage Technology FC only Flexible (FCoE, iscsi, NFS ) Meet Performance Requirements Thick Provisioning Recommended (not required) Flexible RAID Configuration Other Requirements Performance Requirements SAN Kernel Command Latency < 4ms Hypervisor Physical Device Command Latency < 20ms Reference: http://docwiki.cisco.com/wiki/uc_virtualization_supported_hardware NAS Total Guest Latency < 24ms

Storage Array Performance Design Unified CM BHCA Average IOPS 10K ~35 25K ~50 50K ~100 CUCM upgrades generate 800 to 1200 IOPS in addition to steady state IOPS Presence VM Size Average IOPS Unity Connection 1000 users VM size ~60 Average IOPS Peak IOPS 2 vcpu (5,000 users) ~130 ~715 4 vcpu (10,000 users) ~220 ~870 VM Size Average IOPS Peak IOPS 2 vcpu (300 agents) ~150 ~1500 Unified CCX Traffic Type: In general, I/Os are mostly sequential writes Reference: www.cisco.com/go/uc-virtualized > Collaboration Application

DAS Storage Requirements TRC and BE6000 / BE7000 Specs-Based BOM (Disks/RAID controllers) Fixed. Exceptions: Faster/Larger disks ok Flexible RAID configuration Fixed Flexible Thick/Thin Provisioning Thick only Thick recommended 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.

Migration to Virtualization Migration CUCM on MCS CUCM release supporting virtualization Upgrade if current CUCM release doesn t support virtualization DRS CUCM Virtual Follow the normal Server Replacement procedure: DRS backup, Install using the same UC release, DRS restore. Upgrade if current CUCM release doesn t support virtualization. In general, virtualization requires 8.0(2)+.
