SBC SWe for VMware – Server Hardware Requirements

Multiexcerpt
MultiExcerptName SBC SWe for VMware – Server Hardware Requirements
The following table lists the server hardware requirements: Caption 0 Table 1 Server Hardware Requirements    Configuration Requirement Processor Intel Xeon processors (Nehalem micro-architecture or above) with 6 cores and above (processors should support hyper threading). Info title Note Sonus recommends using Westmere (or newer) processors for better SRTP performance. These processors have the AES-NI instruction set for performing cryptographic operations in hardware. Info title Note The supported CPU Family Number is 6 and CPU Model Number must be newer than 26. Refer to Intel Architecture and Processor Identification document for more information. Info title Note ESXi 6.5 and later releases requires approximately 2 physical cores to be set aside for hypervisor functionality. Number of VMs which can be hosted on a server needs to be planned accordingly.  RAM Minimum 24 GB Hard Disk Minimum 500 GB Network Interface Cards (NICs) Minimum 4 NICs, if physical NIC redundancy is not required. Otherwise, 8 NICs (preferably with SR-IOV capability to support future SWe optimizations). Info title Note Make sure NIC has multi-queue support which enhances network performance by allowing RX and TX queues to scale with the number of CPUs on multi-processor systems. Info title Note Only The Intel I350 Ethernet adapter is , x540, and 82599 Ethernet adapters are supported for configuring as VMDirectPath SR-IOV and DirectPath I/O pass-through device devices. The SR-IOV is supported only with 10Gbps interfaces (x540/82599). Ports Number of ports allowed: 1 Management port 1 HA port 2 Media ports     Warning title Warning The  Spacevars 0 product2 software only runs on platforms using Intel processors. Platforms using AMD processors are not supported.

BIOS Setting Recommendations

Sonus recommends the following BIOS settings for optimum performance:

SBC SWe for VMware – Software Requirements The following are the VMware ESXi and  Spacevars 0 product2  software requirements: VMware ESXi Requirements Caption 0 Table 1 VMWare ESXi Requirements Software Version Tested and Qualified Version For More Information vSphere ESXi 5.1 or above VMware 6.0 tested with VM version 11 VMware 6.5 tested with VM version 13 Customized ESXi images for various server platforms are available on VMware and Hardware platform vendor sites. It ensures that all the required drivers for network and storage controllers are available to run ESXi server. Most of the customized ESXi images comes with customized management software to manage server running ESXi software. Customized ESXi images for HP ProLiant and IBM servers are available at: HP Servers Custom Image for HP Servers IBM Servers (under Download images) vSphere Client 5.1 or above   VMware Knowledge Base vCenter Server 5.1 or above   vCenter Server Info title Note The VMware Standard License will be sufficient for SWe SBC unless the PKT interfaces for SBC SWe needs to be configured in Direct IO Pass-through mode. In that case, the Enterprise Plus version of VMware ESXi software is required.

Sonus Recommendations for Optimum Performance

Following are recommended VMware ESXi and

Spacevars
0 product2

virtual machine (VM) configurations. 

General ESXi Recommendations

Following are recommended VMware ESXi configurations:

• Plan enough resources (RAM, CPU, NIC ports, hard disk, etc.) for all the virtual machines (VMs) to run on server platform, including resources needed by ESXi itself.
• Allocate each VM only as much virtual hardware as that VM requires. Provisioning a VM with more resources than it requires can, in some cases, reduce the performance of that VM as well as other virtual machines sharing the same host.
• Disconnect or disable any physical hardware devices (Floppy devices, Network interfaces, Storage controllers, Optical drives, USB controllers, etc.) under BIOS settings that you will not be using to free up interrupt/CPU resources.

• Use virtual hardware version 8 and above while creating new VMs (available starting ESXi 5.x). This provides additional capabilities to VMs such as supporting VM with up to 1 TB RAM, up to 32 vCPUs etc.

VM Configuration Recommendations

Caption
0 Table 1 VM Configuration Recommendations

Info
title Note
Make sure the Processors, ESXi version and VM configuration (vCPUs, vRAMs, Virtual Hard Disk, vNICs, and vSwitch Settings) must be identical for SBC SWe HA pair.

Info
title Note
Make sure that the BIOS and ESXi settings and recommendations must not be changed once it is applied on the server.

Info
title Note
On a server with a single 4 cores processor, ESXi 6.5 and above releases are not supported since there is not enough CPU available for launching 3 vCPUs SBC SWe VM after considering overhead required for ESXi.
