While selecting hardware for Oracle VM environments, many factors need to be considered to be able to pick the right hardware architecture to create your Oracle Cloud project effective. The key factor facts to consider would be the CPU, RAM and storage needs you have to consider hardware vendor certification, kind of internal hard drives, etc.
Vendor certification
The server hardware needs to be jointly using the hardware vendor and Oracle. Only jointly supported hardware product receives vendor support when problems occur and repair tickets are produced.
CPU
Server hardware will most likely be bought with two socket Apple or AMD multiple-core CPUs for medium and small workloads and 4 socket multiple-core CPUs for giant CPU-bound workloads. Probably the most amount of CPU cores or threads an Oracle VM server supports is 160. Oracle VM server maps an internet-based CPU having a hardware thread round the CPU core within the CPU socket. Oracle VM Server supports CPU over-subscription, meaning an online server with 160 CPU cores could over-allocate the entire amount of CPU cores to virtual machines. For instance, an online server through getting an Apple Xeon processor 5600-series CPU with hyper-threading might have around six cores and twelve threads per socket. A Few socket server through getting an Apple Xeon processor 5600-series CPU could allocate 24 virtual CPUs without oversubscribing the physical CPUs. CPU-bound workloads shouldn’t perform servers with oversubscribed CPUs.
RAM
Server hardware will most likely be bought using the physical memory. Oracle VM server doesn’t support memory over-subscription, meaning it can’t pay an energetic Migration or HA request unless of course obviously clearly the server has available RAM for the virtual machines. Getting available RAM on every server provides versatility in relation to adding new virtual machines for that server pool, and to allow Live Migration and HA within the server pool. Instantly, each server reserves 512 MB of memory for dom0. The standard memory overhead for every running guest round the dom0 is roughly 20 MB plus 1% within the guest’s memory size. All individuals other physical memory may be utilized on visitors.
Storage
Unless of course obviously clearly the server is booting from SAN, an SSD internal hard drive is suggested. Virtual machine image and configuration files are available on shared SAN, iSCSI, or NFS repositories. Oracle VM Server requires “only” 4 GB of local storage for the whole installation. The look goal for Oracle VM should be to support multiple node server pools with shared fibre funnel SAN, iSCSI and/or NFS storage.
Network Interface Cards
For network-interface high availability 802.3AD bonds can be used each number of network interfaces. Oracle VM supports two NICs ports per 802.3 AD bond and around five 802.3AD bonds per Oracle VM Server. Both 802.3AD NIC bonds, port-based VLANs and/or 802.1Q tag-based VLANs are supported and configured publish-installation with Oracle VM Manager. Network redundancy, i.e. 802.3AD NIC connecting doubles the amount of needed NICs. Oracle VM uses around five discrete systems – Server Management, Cluster Heartbeat, live Migration, Storage and Virtual Machines. All five systems may be supported one mode 2 bond with 802.1Q tag-based VLANs (2 NICs) or depleting to 5 802.3AD bond (10 NICs).
