IP SAN Technology at a Glance

The maturity and popularity of iSCSI technology makes it re-define the deployment of storage technology. Today businesses are able to deploy a high performance IP SAN by leveraging their storage resources over an existing IP infrastructure without the need for investments of special-purpose cabling for Fiber Channel SAN. Other businesses who have built their FC SAN can also introduce IP SAN by simply installing bridges or gateways in order to construct a Heterogeneous IP SAN to maximize their storage flexibility and availability.

Lower TCO and Higher Flexibility

Alnico iSCSI array's cost-performance offers customers a better alternative and value that rivals FC SAN. Alnico 8161i / 8121i is not only capable of delivering outstanding performance up to 600MBps / 120K IOps in full-duplex mode, but also enables an optimized and cost-effective TCO (total cost of ownership) to be achieved by rapidly deploying IP SAN environments with existing GbE switches and the plentiful IP network that could be painlessly managed and maintained without further ado. Accompanied with hardware built-in snapshot function, Alnico iSCSI RAID can easily replicate several point-in-time data that could be instantly recovered at any time without interrupting production, the built-in snapshot function at the same time cuts down the licensing cost of backup software. With the excellence of cost-performance the Alnico iSCSI array possesses, customers could maximize their storage resource utilization and their TCO will be protected for the future.

ALNICO AL-8121i

| Datasheet  
12 bays 2U Rackmount iSCSI to SAS/SATA-II RAID Subsystem

The Alnico 8 iSCSI series RAID subsystems features Quad Gb Ethernet host and SAS device attachment. The maturity and popularity of iSCSI technology makes it re-define the deployment of storage technology. Today businesses are able to deploy a high performance IP SAN by leveraging their storage resources over an existing IP infrastructure without the need for investments of special-purpose cabling for Fiber Channel SAN. Alnico 8 series takes data reliability and protection for Hosts and offers a advanced technology to implement the extreme performance RAID6 function.

Coupled with AL-8161Ji ( SAS Expander) supporting up to 76 SAS/SATAII devices connected. Alnico 8 iSCSI RAID provides the burgeoning applications with the most high-end data security without sacrificing performance concurrency.

SAS builds on parallel SCSI by providing higher performance, improving data availability, and simplifying system design. The SAS interface supports both SAS disk drivers for data-intensive applications, and serial ATA( SATA) drivers for low-cost bulk storage of reference data. The Alnico AL-8121i can support up to 12 SAS ports to solid backplane and via one external miniSAS 4 x connector for easy expansion . When used with AL-8161Ji (SAS expander), the controller can provide up to 76 devices through one or more AL-8161Ji ,Making it an ideal solution for enterprise-class storage applications that call for maximum configuration flexibility.
