ES5400 MEDIUM The First Affordable High Availability, Flash & Disk Storage Arrays for Small Business

ULTRASTOR  redefines value with the introduction of the ULTRASTOR ES5400, a powerful and easy to use dual active controller storage platform for critical business applications. ES5400 delivers best-in-class SSD flash storage performance to meet your toughest business continuity and IOPS requirements. Select from 10GbE / iSCSI and FC / 1GbE iSCSI connectivity for the ultimate in IT flexibility.



Enjoy Peak Performance

Accelerate your data applications with affordable all-flash and hybrid flash/disk storage solutions. ULTRASTOR ES5400 all-flash systems combine high capacity SAS disk drives with enterprise flash SSD caching for increased storage efficiency in high transactional & random I/O environments such as database, financial, virtualization and web servers/cloud applications.



Main Features


+ Take Control of Your Data

Get total control of how and where you store your data. ULTRASTOR ES5400's integrated SAN environment includes a rich set of storage tools that simplify your data management.




+ SSD Caching (CachePeak 2.0)
CachePeak is a large-capacity secondary cache feature that uses enterprise SSD drives positioned between the SAN controller's primary DRAM memory cache and hard disk drives (HDD). SSD read/write cache extends the ES5400's existing memory cache capacity and functionality by copying frequently accessed data to ultra fast flash disks, boosting system-wide performance by up to 18x.

+ Automatic Storage Tiering
ES5400 performs a continuous analysis of data access trends and intelligently performs a data migration from one media type to another based on frequency. ULTRASTOR storage tiering dynamically places "hot" or frequently accessed data on to enterprise flash disks (or fast hard drives), while distributing infrequent or "cold" data across lower cost high-capacity drives - improving overall system efficiency while preserving valuable flash storage capacity..




+ Array-based Replication
ULTRASTOR remote replication is a system integrated, block-level, asynchronous, differential remote volume backup function that supports data transmission through a local LAN or WAN. Remote Replicaiton 2.0 adds many new features including unlimited bandwidth, traffic shaping, and multiple connections per replication task. Best of all, every ES5000-series system now includes Remote Replication 2.0.





+ Thin Provisioning
Virtually configure storage volumes with future capacity requirements in mind. Purchase only the capacity you need today and increase your physical capacity as you go.




+ DXE™ Hardware Acceleration
Integrated data offload acceleration reduces host CPU utilization and boosts performance at the system level for increased performance and hardware efficiency.
