Comprehensive security : The IBM Storage Networking c-type Family devices supports services   including VSANs, hardware-enforced zoning, ACLs, per-VSAN role-based access control (RBAC),  and TrustSec Fibre Channel link encryption. The comprehensive security framework consists of  RADIUS and TACACS+, FC-SP, SFTP, SSH Protocol, and SNMPv3. The TrustSec Fibre Channel  link encryption delivers transparent, hardware-based 32-Gbps line-rate AES 128-bit encryption of  Fibre Channel data on 32-Gbps Fibre Channel switching modules. Resilient high-performance ISLs: The IBM Storage Networking c-type Family 32-Gbps Fibre Channel   switching modules support high-performance ISLs consisting of 32-Gbps secure Fibre Channel. Fibre  Channel switching modules also support port-channel technology for additional scalability and  resilience. Administrators can group up to 16 links spanning any port on any module in a chassis into  a logical link.  Sophisticated diagnostics : The 48-Port 32-Gbps Fibre Channel Switching Module provides intelligent   diagnostics, protocol decoding, E-port diagnostics, and network analysis tools along with an  integrated Call Home capability for greater reliability, faster problem resolution, and reduced service  costs. Compatibility: The 48-Port 32-Gbps Fibre Channel Switching Module can co-exist with   previous-generation supported modules on the IBM Storage Networking c-type Family director. Investment protection: The 48-Port 32-Gbps Fibre Channel Switching Module can easily be inserted   into existing IBM Storage Networking c-type Family directors without any impact on operations. Lower TCO with SAN consolidation: With the exponential growth of data in today's business   environment, organizations need to deploy large-scale SANs in the most efficient and cost-effective  ways. To meet scalability requirements while managing TCO, the IBM Storage Networking c-type  Family directors offer the following features: Industry-leading port density of line-rate 32-Gbps Fibre Channel ports per chassis o 1.5-Tbps Fibre Channel performance per slot o Up to 48-Tbps front-panel Fibre Channel line-rate, non-blocking, system-level switching o Exceptional capabilities with intelligent fabric services o VSANs for consolidating individual physical SAN islands while maintaining logical boundaries o IVR for sharing resources across VSANs o Built-in network processing unit for inline analytics o Main benefits Administrators can also allocate up to 8191 buffer-to-buffer credits to a single Fibre Channel port,  providing industry-leading extension of storage networks to up to 4,000 kilometers at 4 Gbps, 2,000  kilometers at 8 Gbps, 1,000 kilometers at 16 Gbps, and 500 kilometers at 32 Gbps, while maintaining  full link utilization. The IBM Storage Networking c-type Family switch architecture helps ensure that  frames are never reordered within a switch, leading to optimal application performance because end  devices never have to use resources to reorder the frames.
