Okay-this is going to be a short post as I am off to party for the rest of the day.Hyper-V has RTM 'd!Press release here: http://www.microsoft.com/presspass/features/2008/jun08/06-26hyperv.mspxJohn Howard has install directions here: http://blogs.technet.com/jhoward/archive/2008/06/26/hyper-v-rtm-announcement-available-today-from-the-microsoft-download-centre.aspxAnd my favorite-Qlogic reports getting up to 180,000 iops at 88-97% native performance on

between the iSCSI server and the storage device.Iscsi adapter cards are roughly divided into two categories: toe HbA cards and iSCSI HbA cards. The former is cheaper, while the latter is more efficient, but the latter is very expensive. Representative vendors include adaptec, alacritech, Intel, LSI, and Qlogic. Intel focuses on the development of toe HbA cards. 1.3. iSCSI target Iscsi target is an iSCSI disk array that can be used to store data or a

server architecture. The IBM bladecenter Blade Server integrates all types of servers and peripheral application devices by means of outward expansion, which improves the system integration and facilitates the management of servers and peripheral devices. Is a typical system architecture diagram, including servers, network switches, firewalls, and optical fiber switches. for traditional servers, if you want to complete these functions, you must follow the above methods, as you can imagine,

the original server to complete the addressing forwarding. The entire flow of data is like a hairpin around the top switch, so this behavior is also known as "card-issuing forwarding." In order to achieve "card-issuing forwarding", Vepa needs to modify the spanning tree protocol, or force the behavior of reflection data frames on the upper-end port (reflective Relay). At the same time, Vepa uses q-in-q technology to add a layer to the basic 802.1q tag to represent the definitions of different v

As the server's IO starts to be slightly inadequate, a QLogic FC card needs to be installed to increase server and storage performance. This article describes the example Where Openfiler 2.99 enables FC and creates target. (Note: Please replace the characters in 1.unmap a volume, this step can be done through the Openfiler Web interface. 2. Enable FC Target in the service of the Web interface 3. Run the following command to enable Vdisk_fileio an

integration and synergy. Setting standards will enable administrators to trust FCoE and CEE on virtualization and blade servers on the periphery of the data center, and to be able to trust their capabilities in the datacenter core environment. Although the standard has not yet been formally established, but has attracted enough manufacturers and enterprises to bring commercial products to the adopters, is expected 2010 FCoE and CEE will become mainstream products. In addition, most of the stora

amount to time or a error was returned for a SCSI request, the M ID level manages the error or retries the request. The mid level also manages higher-level recovery such as requesting an HBA (LLD) or SCSI device reset. The SCSI error and timeout handler is implemented in./linux/drivers/scsi/scsi_error.c. Back to Top SCSI Lower Level At the lowest level is a collection of drivers called the SCSI low-level drivers. These are the "specific drivers" interface to the physical devices as such. The LL

With future upgrades to file system protocols, such as NFS (including concurrent NFS, or PNFS), will NFS potentially replace many of the existing proprietary file systems? Let's take digitalfilm tree for example, a company in Hollywood that provides post-processing and virtual effects services for the entertainment industry. The company employs products that include Apple Xsan, HP storageworks arrays, QLogic switches, and other storage vendors. They

In this transaction, Marvell will acquire Cavium all circulating stocks, $40 per share in cash plus 2.1757 shares Marvell common stock, equivalent to $80 per share, with a total transaction price of $6 billion.

Currently, the more popular raid includes the RAID0,RAID1,RAID5 and their comps. RAID0 provides the functionality of stripe, and simply pieced together the disks in the array, and any one of the disks is destroyed, resulting in a total annihilation; RAID0 provides the mirror function that two

In addition, what network parameters are used to the overall performance and robustness of the cluster have a great relationship.Case:XX City, 4 node Oracle 10g RACThe operating system uses RHEL 4, according to the default installation documentation, set the network parameters to the following values:Net.core.rmem_default = 262144Net.core.rmem_max = 26

several ports. Large products have hundreds of ports for large systems. Supported protocols include the open system SCSI Optical Fiber Channel Protocol (SCSI_FCP a.k. a. FCP) and the FICON protocol supporting the IBM mainframe environment. Currently, the storage LAN switches have two major speeds: 1G and 2G. Most vendors believe that the next major speed should be 4G and 10G. At the same time, this type of Ethernet switch provides many new security protection features, IP-based storage features

Linux auto-loading driver module-general Linux technology-Linux programming and kernel information. The following is a detailed description. The RHEL4u5 kernel does not support the new Qlogic 4g fc memory card. Download the driver from the official website and compile it into a module. 1. Download and compile the driver. In this step, see the driver Readme. 2. Generate the initrd file: Mkinitrd-v -- with = qla2xxx_conf -- with = qla2xxx -- wi

Mutual backup mode of clusters: Working principle: multiple hosts work together, each running one or several services, each defining one or more backup hosts for the service. When a host fails, services running on them can be taken over by other hosts.

Each high-speed data receiving processing board connects two SCSI disks and controls the data storage for one channel.The LVDS signal Adapter board mainly completes the physical connection of the input signal, the level conversion and the timing logic adaptation of the data processing board. The signal of the LVDS signal Adapter board output is sent to the high-speed data receiving processing board throu
