2.FEATURES OF ADDITIONAL DISK ENCLOSURE

The additional disk enclosure has the following features.

NF2300-SE41E is a high-performance additional disk enclosure developed for the NF2300-SR4xxE disk array unit connected to the NEC Express5800 basic processing unit, NX7000 basic processing unit, or CX5000 basic processing unit.

The additional disk enclosure NF2300-SE41E is not equipped with disk drives at the shipment. To use the additional disk enclosure, add disk drives sold separately.

Up to 15 disk drives can be installed in NF2300-SE41E.

The disk drives for disk array unit NF2300-SR4xxE can be added by connecting the additional disk enclosure NF2300-SE41E (up to 13 disk enclosures, 210 disk drives).

The combination of the additional disk enclosure and disk array unit NF2300-SR4xxE enables a defected disk drive to be replaced with a new one without system shutdown. Further, the additional disk enclosure has the auto rebuild feature which automatically starts data recovery after the replacement of the defected disk drive.

If a single disk drive is specified as the spare disk, the data in the defected disk drive can be immediately recovered in the spare disk. The use of this hot spare feature as well as the auto rebuild feature allows the data in the defected drive to be automatically recovered in the spare disk as soon as a disk drive is defected. This improves the system reliability.

Refer to "NF2300-SR4xxE Disk Array Unit User's Guide" for details of hot spare feature.

Further, owing to the redundant configuration of the adapter and power supply, the entire system is not shut down if any part of the system is defected during operation.

See Section 9.2 "Optional Components" for the product names and part numbers of options.
