Supported Hypervisors

The SLB supports the following hypervisors for version S-Cz9.2.0:

• KVM: Linux kernel version (4.1.12-124 or later), with KVM/QEMU (2.9.0_16 or later) and libvirt (3.9.0_14 or later)
• VMware: vSphere ESXi (Version 6.5 or later)

Supported Public Cloud Platforms

You can run the S-Cz9.2.0 SLB over the following public cloud platforms.

• Oracle Cloud Infrastructure (OCI)

  OCI Cloud Shapes and options supported by this release are listed below. After deployment, you can change the shape of your machine by, for example, adding disks and interfaces.

  Shape	OCPUs/VCPUs	vNICs	Tx/Rx Queues	Max Forwarding Cores	DoS Protection	Memory
  VM.Standard2.4	4/8	4	2	2	Y	60
  VM.Standard2.8	8/16	8	2	2	Y	120
  VM.Optimized3.Flex-Small	4/8	4	8	6Foot 1	Y	16
  VM.Optimized3.Flex-Medium	8/16	8	15	14Foot 2	Y	32
  VM.Optimized3.Flex-Large	16/32	16	15	15	Y	64

  ^Footnote 1 This maximum is 5 when using DoS Protection

  ^Footnote 2 This maximum is 13 when using DoS Protection

  Networking using image mode [SR-IOV mode - Native] is supported on OCI. PV and Emulated modes are not currently supported.

  Note:

  Although the VM.Optimized3.Flex OCI shape is flexible, allowing you to choose from 1-18 OCPUs and 1-256GB of memory, the vSBC requires a minimum of 4 OCPUs and 16GB of memory per instance on these Flex shapes.
• Amazon Web Services (EC2)

  This table lists the AWS instance sizes that apply to the SLB.

  Instance Type	vCPUs	Memory (GB)	Max NICs
  c5.xlarge*	4	8	4
  c5.2xlarge	8	16	4
  c5.4xlarge	16	32	8
  c5.9xlarge	36	72	8
  c5.12xlarge	48	96	8
  c5.18xlarge	72	144	15
  c5n.xlarge	4	10.5	4
  c5n.2xlarge	8	21	4
  c5n.4xlarge	16	42	8
  c5n.9xlarge	36	96	8
  c5n.18xlarge	72	192	15

  * — Hyperthreading must be disabled for this shape.

  Note:

  C5 instances use the Nitro hypervisor.

  Note:

  ENA is supported on the C5/C5n family.
• Google Cloud Platform

  The following table lists the GCP instance sizes that you can use for the SLB.

  Table 1-1 GCP Machine Types

  Machine Type	vCPUs	Memory (GB)	vNICs	Egress Bandwidth (Gbps)	Max Tx/Rx queues per VM
  n2-standard-4	4	16	4	10	4
  n2-standard-8	8	32	8	16	8
  n2-standard-16	16	64	8	32	16

  Use the n2-standard-4 machine type if you're deploying an SLB that requires one management interface and only two or three media interfaces. Otherwise, use the n2-standard-8 or n2-standard-16 machine types for an SLB that requires one management interface and four media interfaces. Also use the n2-standard-8 or n2-standard-16 machine types if deploying the SLB in HA mode.

  Before deploying your SLB, check the Available regions and zones to confirm that your region and zone support N2 shapes.

  On GCP the SLB must use the virtio network interface card. The SLB will not work with the GVNIC

OpenStack Compatibility

Oracle distributes Heat templates for the Newton and Pike versions of OpenStack. Use the Newton template when running either the Newton or Ocata versions of OpenStack. Use the Pike template when running Pike or a later version of OpenStack.

Oracle distributes Heat templates for the Newton and Pike versions of OpenStack. Download the source, nnSCZ920_HOT.tar.gz, and follow the OpenStack Heat Template instructions.

The nnSCZ920_HOT.tar.gz file contains two files:

• nnSCZ920_HOT_pike.tar
• nnSCZ920_HOT_newton.tar

Use the Newton template when running either the Newton or Ocata versions of OpenStack. Use the Pike template when running Pike or a later version of OpenStack.

Platform Hyperthreading Support

Of the supported hypervisors, only VMware does not expose SMT capability to the SLB. OCI, AWS and GCP enable SMT by default and expose it to the SLB.

DPDK Reference

The SLB relies on DPDK for packet processing and related functions. You may reference the Tested Platforms section of the DPDK release notes available at https://doc.dpdk.org. This information can be used in conjunction with this Release Notes document for you to set a baseline of:

• CPU
• Host OS and version
• NIC driver and version
• NIC firmware version

The DPDK version used in this release is:

• 21.11
