Unparalleled Performance
For users that need their data in a hurry, the i5500/i4500R has them covered. The i5500/i4500R brings unparalleled data throughput via iSCSI. With a powerful Intel® XScale CPU and 512MB of DDR memory, the i5500/i4500R delivers blazing performance for even the most demanding storage user.

Uninterrupted RAID Capacity Expand
Need to add more storage capacity to the i5500/i4500R but can't afford the downtime? The i5500/i4500R features online RAID capacity expansion, which means that users can have bigger hard disks added to available slot and joining an existing RAID without having to power down the system. The i5500/i4500R will automatically rebuild your RAID array and increase your storage capacity with zero downtime.

Dynamic Volume Management
With the i5500/i4500R, flexibility is the name of the game. With the i5500/i4500R, users can change volume sizes on the fly without having to reboot or restart the system. Is your database starting to outgrow the space you originally allocated it? Simply reconfigure the volume from the web interface and assign unused capacity to your existing volume without any service interruptions.

Cost Effective
The i5500/i4500R is far and away the price/performance leader. Instead of setting up a costly and complicated fiber channel network throughout your office for block level data sending, the i5500/i4500R accomplishes this via iSCSI. With the i5500/i4500R, users can obtain close to fiber channel class performance at a fraction of the cost.

Easy Integration
With its dual Gigabit Ethernet ports, the i5500/i4500R was designed to be easily integrated into existing network infrastructures. Simply connect the i5500/i4500R to your Ethernet network and begin enjoying legendary Thecus performance and data security.

Overview

In 2007 Thecus released its first rack mount 1U4500 NAS storage device. Aimed at SMBs, the 1U4500 offered incredible performance and a feature set that was never before seen on such a compact unit. This year, Thecus is poised to raise the bar yet again with its most powerful storage device yet – the i4500R. Delivering unprecedented iSCSI performance, uninterrupted data capacity expansion, and air-tight security in a cost effective package, the i4500R offers an unbeatable value proposition for enterprises looking to store and secure mission-critical data.

When businesses need access to their data, they need it fast. The i4500R comes with in Intel® Xscale IOP80331 CPU and 512MB of DDR memory under the hood. This enables the i4500R to deliver incredible iSCSI performance – up to twice the performance of its predecessor the 1U4500! With block level data transmission over regular Ethernet, businesses can forgo the prohibitive costs of implementing a fiber channel network altogether. The i4500R comes with four hot-swappable SATA drive bays that accommodate up to 4TB of storage. A wide selection of RAID modes including RAID 0, 1, 0+1, 3, 5, 6, 10, and JBOD as well as instant RAID volume availability, auto volume rebuilding, and support for up to 256 logical volumes offers unbeatable flexibility. And because downtime equals lost revenue, the i4500R also features online RAID expansion allowing businesses to increase their storage capacity without taking down their system. With the i4500R businesses can rest easy knowing they can access their data at all times.

Of course, keeping data safe and secure is also of prime importance. Included with the i4500R is Logical Unit Number (LUN) support, enabling administrators to specify read and write access to specific hosts accessing the unit through the iSCSI protocol. The i4500R also packs advanced data protection capabilities in its compact housing, including Local N-way mirroring, offline array roaming and smart faulty sector relocation. Compatibility with all major operating systems including Windows NT/XP/2003/Vista, Mac OS 9.1 and above including OSX, OSX Server and XSERVE, and all Linux builds with SCSI support ensures seamless integration with existing corporate environments. Administration can be conveniently performed through Thecus’ sterling web interface, and should something go amiss, the i4500R can notify administrators immediately via email or SNMP trap.

“We created the i4500R with total performance and security in mind,” notes Thecus General Manager Florence Shih. “Following in the footsteps of our acclaimed 1U4500, the i4500R represents a new industry benchmark for enterprise-level data storage devices, and is ideal for businesses looking for block level data transmission without the hassle and expense of fiber channel.”
