True SATA argument about the correct yes: ATA to SATA transition from parallel to serial shift Can be seen as a special NAS file server, mainly for storing, sharing, and data transmission block: False A dual-port the FC-HBA card, there are two numbers WWNN False Windows you can view the host HBA card wwn number through the operating system commands. False Under common windows file system, including: (Choose two) ntfs fat32 S5600T and S6800T when the system power loss by the built- safe dish BBU to power, to ensure that the data written to the Cache dirty safe dish without losing. False When installing UltraPath for Linux, prompted "the system is not supported by UltraPath driver, exit!!", Requires: Check the server operating system type and version is supported by multi- path software SCSI Fibre Channel protocol stack is located in the first floor: FC4 Compared with the traditional N8000 NAS device, which has the following advantages: (Choose three) Mass of storage space and scalability Concurrent multi-user access and full sharing Ease of use and availability clustering equipment SUSE Linux 10.0 modify the startup which you need to edit the file name: etc / iscsi / initiatorname.iscsi RAID0 often called bands, RAID0 allowed to damage a member of the hard drive data is not lost. False For S5000T, the following statement is correct: (Choose three) After the LUN must be formatted before use mapping to the host Both can be mapped to a host LUN group also mapped to the host S5000T product 8Gb FC host port rate currently supports 4G, 8G and adaptive After storing the file import license, you need to reboot the array False S5500T controller hardware supports 3.5 -inch hard drive, a 2U control box. False RAID5 disk utilization levels of RAID group (N: number of member disks): (N-1) / N RAID6 using calibration techniques are there? (Choose two) RAID6 P + Q RAID6 DP NAS and SAN network storage, file system storage resources are used by the host application created. False In RAID systems, different set of disk blocks on the hard drive of the same address is called (), the larger the size of the relationship between its performance and storage read and write. Strips Huawei official maintenance tool bag storage devices, including what tools: (Choose three) Information-gathering tool Inspection Tools Upgrade Check Tool Under Linux system, view and create a GPT disk partition command is parted S5000T product version upgrades in the correct order is: Upgrade Control Software - > multipathing software upgrade The default port iSCSI protocol used is; TCP: 3260 SAN storage system configuration files cannot be imported after export False When installed on Windows 2003 UltraPath for Windows, in Device Manager: If the installation is successful, displays "Multi-Path Support" Direct Connect networking advantages S5000T description right there () (Choose two) Network build low cost; Proprietary data channel can ensure maximum throughput applications between servers and storage devices The basic starting point of the storage network is separated from the storage server, allowing them into a network storage device directly connected to the network. True The following are journaled file system? (Choose three) ntfs jfs xfs Which of the following tools before using the tool comes first modify the configuration file: (Choose two) Upgrade Check Tool Inspection Tools S5600T is redundant management module, on which the system management network port and serial port, on-board control system disk configuration, is one of the key components belong to the system. True Before creating a RAID operation needs to be done to prepare? (Choose three) Login ISM inspection equipment hardware and software status View system alarms,alarms need to be addressed if there is a fault and resume Planning RAID configuration parameters,such as the number,grade,type of hard disk space,etc. BBU parts Huawei disk array can be external to the system in case of a power interruption, the control box and the disk frame power supply, to avoid data loss in the array controller Cache. False S2600 storage control boxes and boxes of Cascade Cascade method, about two links, while cascading from the order 0-1-2, 0-2-1 in the order in accordance with the other side of the connection. Simply summarized as "side forward (order) connection, while the reverse (reverse order) connection."
