Original Press Release:

Chelsio Releases Unified Storage Server (USS) 2.1 -- Delivers High Availability, iSCSI Scaling to Petabyte Level for Cloud Installations

SUNNYVALE, Calif. -- Chelsio Communications, a leading provider of 10Gb Ethernet Unified Wire adapters, ASICs and unified storage solutions, today announced the release of Unified Storage Server (USS) 2.1 software, adding new features that enable more than one million IOPS performance with new levels of reliability and scalability for low cost Ethernet storage in enterprise data centers and cloud computing installations.

Among the new features included in USS 2.1 are high availability (HA), iSCSI scalability, and live migration for storage networks. Together with fully integrated support for Chelsio T4 Unified Wire 10Gb Ethernet adapters, Chelsio is delivering a highly scalable and reliable storage solution with far greater performance and lower costs than comparable Fibre Channel solutions.

For example, hybrid cloud service provider Vivavo ( is deploying Chelsio USS 2.1 to create a single HA head that scales to 0.5 Petabyte (500 Terabytes) installation with high performance, ease of use and integration. "Chelsio's USS software has proven to be a tremendous asset to enabling high performance, scalability and high reliability for storage clouds," said Francis Au, executive director of Vivavo. "The combination of USS and the T4 adapters is a powerful, scalable solution for our cloud storage applications."

The new features of USS 2.1 include:

-- High Availability, including dual-node HA and nested RAID support
-- iSCSI Scaling, leveraging multiple distributed iSCSI targets for up to one Petabyte of storage capacity
-- Live Migration, enabling swap out for higher capacity storage disks without disconnecting or affecting clients and applications
-- Lustre over RDMA support for targeted HPC applications
-- Support for wide range of RAID and SSD cards
-- Enhanced support for 4-port 10GbE and 40GbE T4 Adapters to enable fat pipe into storage targets

The feature-rich USS software supports iSCSI target, CIFS, NFS, FTP, HTTP, Thin Provisioning volumes, Volume cloning, snapshots, instant restore from snapshots, volume encryption and replication compression. A single-seat USS 2.1 license is US List priced at $5,168. For more information on USS 2.1, visit the Chelsio USS Software product page.
