2840e/3850c/4450c/4480i: Our controller offers versatile connectivity options, including 24GB, 12GB, and 6GB SAS/SATA, 64Gb, 32Gb, 16Gb Fibre Channel (FC), and Thunderbolt 3,4. With native support for SAS and SATA disk drives, it empowers robust and cost-effective storage solutions, catering to the needs of both gamers and professional enterprises.

The dual-active 3840 controllers are seamlessly integrated into a compact SAS drive enclosure, creating a fully featured 24-drive storage system in a space-saving 2U module. You can expand your storage capacity further by adding up to 128 additional SAS or iSCSI drive enclosures, allowing for a maximum storage capacity of 20PB with 352 disk drives. This makes it an ideal solution for entry-level to mid-level and secondary storage requirements.

Designed to deliver superior features and functionality, our entry-level controller excels in direct-attach (SAS) and storage area network (SAN) environments. The dual-active 4890 controllers are integrated into a high-performance SAS drive module, enabling a fully featured 24-drive storage system within a robust 4U enclosure. For enhanced performance with high IOPS and capacity, additional SAS drive modules can be seamlessly added.

Combining high-speed, industry-standard components with our reliable Nomadic firmware, the 3850c controller offers enterprise-class functionality and exceptional value. Each 4450c controller features 4x64Gb/s Fibre Channel host I/O ports (8 per dual-controller storage system), supporting direct host or SAN attachments. The controller's native support for up to 24 24/12GB SAS drives in the initial enclosure can be expanded using the 3890 64/32/16 Gb/s FC expansion ports. Dual drive loops created through the interconnection of the FC drive side ports provide redundant access to all attached disk drives for both controllers in dual-controller configurations.

The 4450c controller boasts a high-speed bus capable of handling large block I/O for superior IOPS, as well as efficient processing of small block I/O. Its I/O system core features built-in hardware XOR for high-speed RAID parity calculations, enabling the controller to effortlessly handle compute-intensive tasks. With online configuration, reconfiguration, expansion, performance tuning, and firmware maintenance, administration becomes a breeze. All our GVS enterprise controllers, ranging from the entry-level 4480i iSCSI 10Gbit Option to the high-end models, run on the same firmware. This uniformity ensures a lower total cost of ownership, higher return on investment, seamless integration of FC or iSCSI in any mixed server environment, and easy upgrades and reconfigurations. Additionally, common features and functionality, centralized management, a consistent interface, and reduced training and support costs further contribute to a smooth and efficient experience. With our extensive experience in the storage market and ongoing R&D efforts, we are proud to offer our customers the ability to achieve 99.9999% availability, as demonstrated by our track record.
