, load balancing, and disaster backup functions, high-speed network interconnection is also an essential condition. Therefore, Oracle Exalytics provides the following network interfaces to support the above requirements: InfiniBand: Each Exalytics provides two InfiniBand ports with a four data rate (QDR) of 40 Gbit/s. When Exalytics is connected to Exadata, Exalytics becomes an integrated part of the Exadat

Introduction to memory card knowledge 1. Common memory card related concepts HBA and WWN first introduce what is HBA. The HBA mentioned here is the full name of fc hba, that is, the Fiber Channel Host Bus Adapter. In an FC network, when a host (such as a server) needs to be connected to an FC network or an FC storage d

contains two core components: the Clusport and Clusblft,clusport implement a virtual HBA interface, which enables the connection of the server disk devices under all cluster nodes. The CLUSBLFT implements the virtualization encapsulation of all the disk devices and headers connected through the Clusport; the storage component stack in Windows Server 2016 is as follows, where the green part is the two software storage bus components.650) this.width=65

Organization of storage through similar protocols with low-cost and significant configuration flexibility and scalability, especially for large cluster environments and cloud environments. For a shared-storage environment, you no longer need to configure expensive HBA cards or FCoE cards for each connection, not to build expensive fibre connections, and you don't have to repeatedly modify the upper-end WWN for a storage group configuration to avoid t

performance and availability. With Sun's industry-standard hardware and Oracle's intelligent database and storage software, the Exadata appliance delivers superior performance for all database load types, including online transaction processing (OLTP), Data warehousing (DW), and hybrid load consolidation. The Exadata all-in-one implementation is simple and fast, capable of handling the largest and most important database applications, and typically allows these applications to run up to 10 time

This article will briefly introduce the Java Socket Direct protocol (Sockets Direct PROTOCOL,SDP) introduced in the Java 7 SDK, and this new technology is a very exciting breakthrough. If you want to native access to InfiniBand's remote Direct memory access (Sqlremote direct Memory ACCESS,RDMA), SDP enables ultra-high performance computing (Ultra high Performance Computing, UHPC) Community uses Java-generic features and advantages in this uncommon scenario. RDMA provides a protocol for low laten

connectivity The mobility and recoverability of server virtualization implementation depend on external shared storage, and these functions are most effective in SAN connection environments. Generally, virtual servers are deployed in the primary data center and the enterprise's storage resources are obtained through the fiber channel protocol. The high performance brought by fiber channel can meet the high I/O requirements of multiple virtual machines running on one server. SAN connections can

Emulex in the Linux field-Linux Enterprise Application-Linux server application information. The following is a detailed description. With the increasing influence of Linux in the server field, more and more software and HBA vendors are showing great interest in this little penguin. In the fc hba market, Emulex, which leads with QLogic in turn, has already become a member of the Linux team. Features of Emu

Work: Iscsi host connectivity requires a hardware component, such as a NIC with a software component (iSCSI initiator) or an iSCSI HBA. in order to use the iSCSI protocol, a software initiator or a translator must be installed to route the SCSI commands to the TCP/IP stack. A standard Nic, a TCP/IP Offload Engine (toe) Nic card, and an iSCSI HbA are the three physical iSCSI connectivity options. A sta

process of storing I/O (hereafter referred to as I/O) is the process by which the computer reads data and writes data on the memory. This memory can be either non-persistent storage (RAM) or a persistent storage similar to a hard disk. A complete I/O can be understood as a data unit that completes the bidirectional process from the initiator to the receiving end. In an enterprise-class storage environment, this process passes through multiple nodes, and each node uses a different data transfer

Can I recognize a device without restarting the host after I have added a new LUN to Linux? What are the commands for dynamically adding/removing LUNs If PowerPath is installed? This article summarizes the way that Linux hosts reconfigure disk devices and attaches command instances.More informationThe Linux system provides multiple mechanisms to rescan

In discussing this issue, a problem needs to be made clear: we know that in the early San storage system, the data transfer between the server and the switch was done through fiber, because the server was transferring SCSI commands to the storage device and not the IP protocol of the normal LAN network, so it needed to use FC transport. So the SAN is called Fc-san, and the late advent of the San with the IP protocol package, you can completely walk the normal LAN network, so called Ip-san, which

between different instances, but also can be used for heartbeat and regular communication. If the connection fails, the cluster is reorganized to avoid split-brain. Grid infrastructure restarts one or more nodes. You can configure a separate connection between RAC and grid infrastructure. In this case, you need to configure RAC to use the correct connection. This connection should always be private and should not be disturbed by other networks. RAC users can use two technologies to achieve inte

Hyper-v Server Virtual Fiber ChannelThe new virtual Fiber Channel (VFC) in Windows Server 2012/R2 enables Hyper-vclient to access the physical storage host bus adapter (HBA) installed on the Hyper-V Server ). Generally, Hyper-VPC is equipped with storage adapters. However, with the help of this new feature, all Hyper-V 3.0/4.0 clients with the corresponding O/S level can access the HBA and directly connect

When discussing this issue, we need to clarify one question first: we know that in the early SAN storage system, serversAndThe data transmission of a vswitch is performed through optical fiber cables. Because the server transmits SCSI commands to storage devices and cannot use the IP protocol of a common lan network, FC transmission is required.It is called the FC-SAN, and later appeared with the IP protocol encapsulation of San, can completely take the common lan network, so called the IP-SAN,
