    In addition, recovery in short time is possible even if disorder occurs in NAS housing by any chance. (※ NSB-5A1BL series is RAID non-correspondence model.)

    ※Please refer to corresponding table for conversion-response model.

    [RAID shift image by product upgrading]

    We spread and display image

    Disk roaming

    Setting information including RAID is automatically succeeded when we replace HDD in 4 bay models.

    ※On disk roaming execution, please attach HDD to replace in new NAS to bay number same as NAS before shift.

    Disk expansion

    In state that switched on, addition of disk, RAID shift are possible. Manual setting needs (capacity increase and RAID shift) at the time of disk addition.

    ※When we perform RAID conversion, it is necessary to carry out in order of "RAID1" ⇒ "RAID5" ⇒ "RAID6".
    ※There is not RAID conversion from "RAID1" to "RAID6" directly.
    ※When we transfer RAID level, it is necessary to add one at least HDD.

    [early recovery by disk roaming]

    Recovery in short time, duties resumption are possible to just replace HDD which we used to new NSB-5A/7A series at the time of NAS box body disorder development of emergency, and to be automatic, and to succeed various setting information, retained data including RAID.

    In cooperation with Active Directory, large-scale user group access control is possible.

    It is not necessary to perform management of user in This product by cooperation function with ActiveDirectory because server consolidates.

    ActiveDirectory consolidates

    The number of the groups, shared folder which we can register have 300 cases and high management function.
    We can set access right for user (maximum enrollment 10,000 ※) participating in domain.
    ※Maximum enrollment is not the number of the simultaneous access.

    iSCSI target correspondence. We use NAS + iSCSI at the same time.

    Treat This product made network connection in the same way as local HDD by iSCSI, and function and application of the OS standard are just usable. Enlargement to file server, backup of server are possible, too. It is not necessary to put near PC and server to use for network connection.

    Schedule power on/off

    We can make joint ownership folder into nonindicating

    We can prevent access from general user and malware infection terminal to nonindicating setting folder because it can prevent list of joint ownership folders from displaying when we opened NAS by Explorer.

    Authorization setting to subfolder

    Authorization setting to subfolder is possible. On access right setting of joint ownership folder, we can set access right by the general Linux deployment OS separately in subfolders joint ownership folder which we cannot set or less. (there is not limit of hierarchy)

    Hardware coding

    Exclusive hardware coding engine is equipped with and can keep important data safely. We cannot begin to read data by any chance even if theft includes NAS and built-in HDD.

    The function equipment that is most suitable for operational management in office most suitable for operational management

    We can acquire information by email even if we do not continuously monitor

    "Warning", email notifies to mail address which we appointed at the time of system event outbreak such as "error".
    We support recovery in early stage by identification of prior detection of obstacle and obstacle occurrence point by performing reception setting of notice email.

    Schedule power on/off function

    It is equipped with power on/off function in schedule that can switch on/off power supply in time of day which we set. We can evade power saving and unauthorized access by automatically turning off power supply on duties overtime or holiday. It is configurable individually at the time of power-on/power off every day.

    Schedule power on/off

    Variable cooling fan adoption

    Employ variable fan in consideration of use in office and stable movement, and increase number of revolutions in high load; and cooling ability We increase power and we make low turn in low load and contribute quiet office environment.

    The preparation of emergency including replication function, backup, UPS correspondence is perfect, too! We contribute high reliability.

    Replication correspondence

    Another NAS (※) can reproduce data and always comes by the same period, backup by data in NAS.
    As copying is performed with writing of data to main plane automatically to backup machine when we set replication, we are reliable because minimum can control disappearance of data at the time of emergency.

    The replication function deployment

    ※It is for NSB-5A/7A series.

    In correspondence with TimeMachine, backup of Mac is possible

    We can perform backup by Time Machine from Mac PC in LAN.

    By connecting UPS with USB cable for communication, shut down by abnormal notice from UPS in at the time of the power failure safely and protect This product from obstacle by unexpected blackout.

    UPS correspondence

    Hot swap correspondence. Exchange of disk is possible with switching on

    When abnormality occurs in hard disk as This product supports hot swap, exchange is possible without dropping power supply.
    In addition, locking mechanism is put on each drive unit and prevents from taking out HDD unit by mistake. ※Pictorial image is 6GB model (NSB-5A6T2BL).

    It supports Auto-Rebuild and is reliable at the time of disk obstacle

    As it is equipped with Ohtori build function, restoration of RAID is started automatically just to change disk. (except RAID0, JBOD)


    Application that both cloud and local backup can use together Important data safely backup "NetStor Backup"

    In NAS with RAID function, is necessary tosuruito not thinking about backup?
    When sudden disaster and unexpected trouble occur, we are assumed when we cannot restore data only by RAID function. NAS of ELECOM can take backup safely in standard attached backup application "NetStor Backup".

    For BCP measures backup to cloud service

    "NetStor Backup" which cooperates, and can back up NAS and cloud of ELECOM.
    Even if the NAS body breaks down, and sudden disaster occurs, cloud service that is distant place can restore early by backing up data.

    We are more reliable by combination with local backup

    Backup to cloud service is high, too; time may suffer from restoration a little to be safe, but on the other hand to use the Internet. It is combination with local backup to solve such a problem. Even if main machine breaks down by preparing NAS for backup at hand, we replace with backup machine and can reopen duties immediately.

    Threat to hide behind in convenient NAS! Netstor Virus Scan which protects NAS from viral infection

    Have you not left NAS of office without making virus measures?

    1. In the first place security measure method of NAS does not know CASE1
    2. We left unattended without hand playing management of CASE2 NAS
    3. Introduction of CASE3 security software and update of pattern file are troublesome

    As a result

    NAS becomes mediation of virus and spreads over office!

    NAS becomes mediation of virus and spreads over office!
