Fujitsu ETERNUS4000 验证兼容:

Fujitsu ETERNUS4000 storage systems continue the FUJITSU success story in the mid-range and enterprise segments. This generation of RAID systems is setting new standards in reliability and innovation.

RAID migration: 

• Dynamic data transfer in running operations from LUN to LUN without interrupting operations
• Move data to fast or low-priced hard disks according to access frequency and importance
• Simplifies the ability to leverage new technology

Data Block Guard: 

• Additional data protection on the hard disk via the extra Error Correction Code
• Helps to ensure data integrity both on the disk and in the cache
• Redundant copy: 
• Preventative hard disk drive replacement, based on error threshold monitoring, ensures data redundancy
• Solves the problem of dangerously increasing recovery times within a     RAID group which comes from the increasing capacity of hard disks (1 TB SATA hard disks)

Storage based data encryption: 

• Optional encryption of the data on the RAID system with native 128-bit AES (Advanced Encryption Standard)
• Protection of sensitive data upon removal from storage system
• Simple and cost effective

EcoMode with MAID: 

• (MAID = Massive Array of Idle Disks) Hard disks can be shut down by a scheduled spin-stop period or by auto spin-down
• EcoMode conserves energy and costs
• 3 tiers of storage economics within the same storage system (Tier1: Fibre Channel hard disks for performance;Tier2: Low-cost SATA hard disks; Tier3: MAID)
• 8Gbit/s Fibre Channel connection
• higher speeds, greater storage consolidation
