Synchronization: After creating RAID 1or RAID5, before using, system needs to read-write
the HDD at a fixed speed and adopts an algorithm to calculate. This process is so called
synchronization. During the synchronization, system performance speed is very low.
z
Storage pool: it is a virtual logic device. It can consist of several HDDs and RAID group. It is
a main way to realized virtual storage.
z
Share folder: Local PC access the top path of the share storage space. You can create,
remove, authenticate and set valid user at the storage device. User is only allowed to
operate folder and file performance in the under-layer. According to different share protocols,
it can be divided into SAMBA share folder, NFS share folder and FTP share folder.
z
SAMBA: it is MS network communication protocol software suitable for UNIX. Its core is
SMB (server message block) protocol. SMB is a client /server protocol. User can access
share file system, printer and other resources in the server via this protocol.
z
NFS: It is an abbreviation for network file system. It is a distribution file system. It can allow
the local PC to use the file or peripheral devices of another PC. It is mainly used in UNIX
platform.
z
iSCSI: It is a abbreviation for internet small computer system interface. It is an internet
protocol standard in Ethernet. It is an SCSI instruction set for hardware to be used in IP
protocol layer. Generally y speaking, iSCSI can realize SCSI protocol in the IP network to
realize router option in high-speed 1000M Ethernet.
z
FTP: It is an abbreviation for file transfer protocol. It is a protocol of the TCP/IP protocol
group. It is to transfer file from one PC to another while it has no relationship with PC OS,
location and connection type.
z
CIFS: It is an abbreviation for Common Internet File System. CIFS is an open and cross-
platform running mechanism for the user to ask for file or print service from the server. It is a
standard server message block (SMB) protocol widely used in personnel PC and work
station
z
Management status: It is a device status when controller configure device via web. Actually,
when there is no error or damage, device shall be always in management status.
z
Working status: It is a device status when controller access HDD via network. System is
ready to use after you configure correctly in accordance with this user’s manual. Some non-
device error (such as configuration error, hot swap error) may result in device failure. You
can configure again to boot up the device. But data loss may occur during this process.
