While choosing hardware for Oracle VM environments, many factors must be considered so that you can choose the best hardware architecture to produce your Oracle Cloud project a hit. The important factors to consider are the Oracle VM Server CPU, RAM and storage requirements; you will probably need to consider hardware vendor certification, kind of internal hard drives, etc. Vendor certification The server hardware have to be jointly based on the hardware vendor and Oracle. Only jointly supported hardware product receives vendor support when problems occur and service tickets are manufactured. CPU Server hardware will be ordered with two socket Intel or AMD multiple-core CPUs for smaller than average medium workloads and four socket multiple-core CPUs for giant CPU-bound workloads. The maximum amount of CPU cores or [http://Data.gov.uk/data/search?q=threads threads] an Oracle VM server is capable of supporting is 160. Oracle VM server maps a virtual CPU with a hardware thread over a CPU core inside a CPU socket. Oracle VM Server supports CPU over-subscription, meaning an Oracle VM Server with 160 CPU cores could over-allocate the total number of CPU cores to virtual machines. For example, a server by having an Intel Xeon processor 5600-series CPU with hyper-threading might have up to six cores and twelve threads per socket. A two socket server with an Intel Xeon processor 5600-series CPU could allocate all day and virtual CPUs without oversubscribing the physical CPUs. CPU-bound workloads mustn't be on servers with oversubscribed CPUs. RAM Server hardware will probably be ordered with all the maximum amount of physical memory. Oracle VM server will not support memory over-subscription, meaning an Oracle VM server cannot accept a Live Migration or HA request unless the server has available RAM to the virtual machines. Having available RAM on each server provides flexibility with regards to adding new virtual machines towards the server pool, also to allow Live Migration and HA inside a server pool. By default, each Oracle VM server reserves 512 MB of memory for dom0. The average memory overhead for each running guest on a dom0 is around 20 MB plus 1% from the guest?s memory size. The remaining physical memory may be allocated to guests. Storage Unless the Oracle VM server is booting from SAN, an SSD internal hard disk drive is recommended. Virtual machine image and configuration files are hosted on shared SAN, iSCSI, or NFS repositories. Oracle VM Server requires ?only? 4 GB of local storage for your entire Oracle VM Server installation. The design goal for Oracle VM is always to support multiple node Oracle VM Server pools with shared fibre channel SAN, iSCSI and/or NFS storage. Network Interface Cards For network-interface high availability 802.3AD bonds are used for each and every pair of network interfaces. Oracle VM supports two NICs ports per 802.3 AD bond as well as a total of 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 post Oracle VM Server installation with Oracle VM Manager. Network redundancy, i.e. 802.3AD NIC bonding doubles the variety of required NICs. Oracle VM runs on the total of five discrete networks - Server Management, Cluster Heartbeat, live Migration, Storage and Virtual Machines. All five networks can be supported using one mode 2 bond with 802.1Q tag-based VLANs (2 NICs) or using around five 802.3AD bond (10 NICs). Host Bus desktop adapter ([http://www.sixcoloshop.com/16-intel-pro-1000-mt-8390mt-disklessintel-pro-1000-mt-8390.html www.sixcoloshop.com]) Cards For your storage space network, you will require 2 Host Bus Adapter Cards (HBAs) with the least 4 GFC. Using 2 HBAs eliminate any single point of failure. The HBA card may be chosen approximately 20 GFC using the line-rate and throughput capacity required to the network. By following the above guidelines, you will be able to create Oracle VM environment while using right hardware architecture.Article Source: is the only resource that is certainly entirely [https://Www.google.com/search?hl=en&gl=us&tbm=nws&q=focused focused] on delivering exhaustive coverage in regards to the Oracle Corporation and its technologies.
