RAID6 using calibration techniques are there? (Choose two)
RAID6 P + Q
NAS and SAN network storage, file system storage resources are used by the host application created.
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.
Huawei official maintenance tool bag storage devices, including what tools: (Choose three)
Upgrade Check Tool
Under Linux system, view and create a GPT disk partition command is
S5000T product version upgrades in the correct order is:

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.
The following are journaled file system? (Choose three)
Which of the following tools before using the tool comes first modify the configuration file: (Choose two)
Upgrade Check Tool
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.
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.
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."
What data file formats supported when using the ISM export performance file storage array: (Choose two)
RPO is a measure of how much data is lost in the system after a disaster.
In RAID technology, RAID parity algorithm commonly used checksum algorithm is XOR XOR algorithm.
HDP3500 as a backup server, along with the high-capacity backup space:
Need at least a few hard drives when you create RAID50
Windows have created a dynamic disk volumes can span multiple disks and create fault-tolerant volumes ability volumes on dynamic disks can be a basic volume, it can be dynamic volumes.
When S5000T create Lun, the default write and prefetching strategies are:
Intelligent prefetching, write-back mirror
Optical switches, which uses fiber-optic network directly connected routing methods, the initiator and target devices can establish a direct connection via fiber optic switch routing software to exclusive fiber bandwidth.
NAS server does not support the agreement are:
