![]() ![]() When creating a high availability pair using ASAv, it is necessary to add the data interfaces to each ASAv in the same order. VPN Optimization-See VPN Optimization for additional considerations for optimizing VPN performance with the ASAv.ĬPU pinning is required for the ASAv to function in a KVM environment see Enable CPU Pinning.įailover for High Availability Guidelinesįor failover deployments, make sure that the standby unit has the same license entitlement for example, both units should See Multiple RX Queues for Receive Side Scaling (RSS) for more information. Receive Side Scaling-The ASAv supports Receive Side Scaling (RSS), which is a technology utilized by network adapters to distribute network receive traffic See NUMA Guidelines for more information. NUMA-You can improve performance of the ASAv by isolating the CPU resources of the guest VM to a single non-uniform memory access (NUMA) node. See Performance Tuning for more information. To achieve the best performance out of the ASAv, you can make adjustments to the both the VM and the host. Virtio-This is a para-virtualized network driver that supports 10Gbps operation but also requires CPU cycles. SR-IOV is generally preferred because it has more deployment flexibility. I40evf/ixgbe-vf-Effectively the same as above (DMAs packets between the NIC and the VM) but allows the NIC to be shared across No CPU cycles are required for moving packets. ![]() I40e in PCI passthrough-Dedicates the server's physical NIC to the VM and transfers packet data between the NIC and the VM The following vNICs are recommended in order of optimum performance. The Intel® Xeon® CPU E5-2690v4 processors running at 2.6GHz. The host CPU must be a server class x86-based Intel or AMD CPU with virtualization extension.įor example, ASAv performance test labs use as minimum the following: Cisco Unified Computing System™ (Cisco UCS®) C series M4 server with Make sure to conform to the specifications below to ensure optimal performance. Review the following guidelines and limitations before you deploy the ASAv. It is not possible to change the resource allocation of the disk space. The ASAv deploys with a disk storage size of 8GB. Requires a minimum resource allocation-memory, number of CPUs, and disk space-on the host machine. The specific hardware used for ASAv deployments can vary, depending on the number of instances deployed and usage requirements. You can also redeploy a new ASAv machine with the latest version. If your current ASAv runs with less than 2GB of memory, you cannot upgrade to 9.13(1)+ from an earlier version without increasing the memory of The minimum memory requirement for the ASAv is 2GB. You can deploy the ASAv on any server class x86 CPU device that is capable of running the Kernel-based Virtual Machine (KVM). ![]()
