Main Features and Benefits
Exceptional Flexibility for High-Performance SANs
The Cisco MDS 9148 offers up to 48 autosensing Fibre Channel ports capable of speeds of 8, 4, 2, and 1 Gbps in
a compact 1RU form-factor chassis. With 8 Gbps of dedicated bandwidth for each port and aggregate platform
bandwidth of 768 Gbps, the Cisco MDS 9148 is designed to meet the performance and scalability requirements of
the most demanding environments.
The flexibility of the Cisco MDS 9148 is provided by the Cisco MDS 9148 On-Demand Port Activation license,
which allows the addition of eight 8-Gbps ports. Customers have the option of purchasing preconfigured models of
16, 32, or 48 ports and upgrading the 16- and 32-port models onsite all the way to 48 ports by adding these
licenses. With advanced storage networking capabilities built into the platform, the Cisco MDS 9148 is an ideal
choice either as a standalone departmental SAN switch or as a top-of-the-rack switch or an edge switch in an
enterprise core-edge SAN.
The Cisco MDS 9148 supports hot-swappable autosensing Small Form-Factor Pluggable (SFP) and Enhanced
SFP (SFP+) optics with interfaces for 8, 4, 2, and 1 Gbps. Individual ports can be configured with either short- or
long-wavelength optics for connectivity up to 860 meters (m) and 31 kilometers (km), respectively.
VSANs for Virtualization, Segmentation, and Isolation
VSAN, an industry standard for fabric virtualization capabilities, enables more efficient storage network use by
creating hardware-based isolated environments within a single physical SAN fabric or switch. Up to 32 VSANs are
supported per switch. Each VSAN can be zoned as a typical SAN and maintains its own fabric services and
management domains for added scalability and resilience. VSANs allow the cost of SAN infrastructure to be
shared among more users while helping ensure segregation of traffic and retaining independent control of
configuration on a VSAN-by-VSAN basis.
Integrated VSAN Routing (IVR) for Highly Available, Scalable SANs
To deploy efficient, cost-effective, consolidated storage networks, the Cisco MDS 9148 supports IVR functionality.
IVR allows selective transfer of data traffic between specific initiators and targets on different VSANs while
maintaining isolation of control traffic within each VSAN, thereby maintaining fabric stability and availability.
Integrated IVR lowers TCO by eliminating the need for external routing appliances, greatly increasing routing
scalability while delivering line-rate performance, simplifying management, and eliminating the challenges
associated with maintaining separate systems.
Advanced Traffic Management for Resilient SANs
Advanced traffic management capabilities integrated into the Cisco MDS 9148 simplify deployment and
optimization of core-edge fabrics.
●
Virtual output queuing helps ensure line-rate performance on each port, independent of traffic pattern, by
eliminating head-of-line blocking.
●
Each port group consisting of 4 ports has a pool of 128 buffer credits, with a default of 32 buffer credits per
port. When extended distances are required, up to 125 buffer credits can be allocated to a single port
within the port group. This extensibility is available without additional licensing.
