Fabric virtualization is a technology that significantly re-architects datacenter I/O by using a centralized device, often called an I/O director/gateway or a fabric interconnect. The fabric interconnect contains the physical I/O adapters, such as Ethernet or Fibre Channel, for multiple servers. The physical servers themselves connect to the fabric interconnect through an intermediate high-speed network and present virtual adapters to the attached VMs or bare metal operating system. Management software is used to provision, monitor, and adjust the I/O dynamically.
The Oracle Virtual Networking product line, which is based on technology that Oracle acquired in its purchase of Xsigo Systems circa 2014, consists of a hardware fabric interconnect as well as several supporting software components.
Oracle Fabric Interconnect (PDF datasheet) is the physical hardware device that virtualizes the I/O and fabric. It connects servers to Ethernet networks and storage (FC, iSCSI, NAS) through high-speed, low-latency InfiniBand that runs at 40Gbps per line, with 80Gbps for dual redundant lines. Dynamic virtual NICs and HBAs allow the connected servers to dynamically add or move connectivity, such as with a newly provisioned VM or a live migrated VM. Oracle Fabric Interconnect also includes QoS controls to manage SLAs.
It supports a wide variety of hypervisors and operating systems, including Oracle Linux, Red Hat Linux, Oracle Solaris, VMware ESXi, Microsoft Hyper-V and Windows Server, Oracle VM, and Red Hat KVM. A configuration with eight Oracle Fabric Interconnects can support up to 1,000 connected physical servers
Oracle Solaris 11 Express delivers advanced Oracle Solaris features that have been in development over the past five years. Oracle Solaris 11 Express provides availability features that greatly reduce planned downtime by eliminating traditional patching- and maintenance- related reboots and vastly improving system boot time. It also adds network virtualization and resource management to the complete, built-in virtualization capabilities of Oracle Solaris, providing high-performance virtualization with low overhead.
Oracle Solaris 11 Express also powers Oracle’s Exadata Database Machine X2-2 and Exadata Database Machine X2-8 and Oracle Exalogic Elastic Cloud.
“We are excited to announce the release of Oracle Solaris 11 Express to enable our customers to deploy the new advanced features of Oracle Solaris 11 across a broad set of platforms and our engineered systems: Oracle Exadata and Oracle Exalogic Elastic Cloud,” says John F., executive vice president, Oracle Hardware. “Through the same engineering disciplines that achieved a legendary mission-critical reputation for Oracle Solaris, we are expecting Oracle Solaris 11 to further reduce any downtime by being quicker and easier to deploy, maintain, and update and to deliver a highly efficient virtualized operating system to meet the scale and performance requirements of immediate and future virtualization and cloud-based deployments.”
Things are heating up in the private cloud appliance world. Meet Exalogic Elastic Compute Cloud (EECC), which contains both a full server and storage hardware. It is not an appliance, it is much more!
Exalogic is an Engineered System: an assemblage of best-of-breed storage, compute, network, operating system and software products that are integrated, tested, tuned, optimized, delivered and supported by Oracle as a single factory-assembled unit. Exalogic is not an appliance (customers can disassemble the system and use the components for whatever they like, whenever they like, with full support from Oracle) and it is not a blue-print.
Exalogic is designed to provide extreme high performance, reliability, ease-of-use and versatility without being a proprietary, closed system with high total cost of ownership and vendor lock-in. Exalogic is everything enterprises love about both mainframes and open systems with none of the stuff they don’t. Exalogic is the realization of a new way of looking at the role of IT in the modern enterprise.
