Key considerations for selecting All-Flash storage
" A true all-flash storage system must be equipped with superb performance
and enterprise-class data protection, helping users save costs."
• Single set of functions as
intelligent data
management features,
greatly reducing costs
• Data reduction
technologies such as
deduplication and
compression, saving space,
power consumption, cooling,
and maintenance costs
• No change to IT
architecture, smoothly
connected to the live network
• No change to use habits,
compatible with apps/IT
devices on the live network
• Uninterrupted data
migration. Users are
unaware of the migration.
Cost-effective design Easy maintenance
• Latency < 1 ms, quickly
responding to business
requests
• High performance, free of
business bottlenecks in peak
hours
• Linear performance
expansion, dealing with
unexpected business growth
• Flash protection technologies,
such as wear leveling, ensuring
SSD service life
• Full redundancy architecture and
RAID technology, ensuring high
availability of the system
• Advanced data protection features
such as snapshots, replication, and
active-active design, ensuring
business continuity
Ultimate
