INFORTREND AND LSI LOGIC SUPPORT LARGE RAID VOLUMES 

First External RAID Support for Storage Arrays Greater than 2TB 

SANTA CLARA, Calif., October 6, 2004 - XRAID storage expert Infortrend today announced that, utilizing an LSI 

Logic host bus adapter (HBA), it has become the first external RAID storage vendor to provide support for storage 

arrays with up to 64 terabytes (TB) capacity. This innovation capitalizes on the new 16-byte SCSI commands, which 

enable breaking the traditional 2TB industry limit. High capacity arrays are ideal for simplified volume management and 

applications involving large reference data files such as medical images.  

“Taken together, Infortrend and LSI Logic have introduced the first native support for a volume size up to 64TB as a 

single LUN. This allows for greater economies of scale well beyond the typical 2TB SCSI limitation,” said Tony Asaro, 

senior analyst, Enterprise Strategy Group. “Typically storage systems require multiple arrays to manage this much 

storage. By supporting up to 64TB as a single LUN, Infortrend is driving down storage total cost of ownership for its 

customers.” 

Simplified volume management has taken on particular importance as high-capacity SATA RAID arrays can now 

contain up to 6TB in one enclosure. Subdividing each enclosure into multiple partitions can be inefficient and present 

difficulties in storage management. Using standard format 512-byte disk blocks, Infortrend's latest firmware supports the 

new 16-byte SCSI command variations such as READ(16) and WRITE(16), which allow for 16-byte Command 

Descriptor Blocks (CDB), resulting in the ability to address greater than 2TB of storage and present it as a single Logical 

Unit Number (LUN). 

“The 2TB limit has long been a barrier to efficient storage provisioning. However, by leveraging the Linux 2.6 kernel 

and the EonStor™ RAID with LSI Logic HBA combination, we can create single file systems well over 2TB,” stated 

Erik Logan, CTO at Pogo Linux. “This provides a valuable solution for higher end markets that require a large 

contiguous storage area.” 

“As high-capacity SATA enclosures become increasingly common, and with the advent of 64-bit operating systems, the 

ability to support new 16-byte SCSI commands delivers a distinct advantage for users in terms of efficiency and 

simplicity,” said Thomas Bayens, director of marketing at Infortrend. “This is especially important for the vast amount 

of reference data being made available for nearline applications.” 

Infortrend has demonstrated this capability with an EonStor SATA subsystem directly attached to LSI Logic's
