Ip Storage; Call Home; Qos And Congestion Control - Cisco DS-C9216I-K9 Configuration Manual

Chapter 1 Product Overview

IP Storage

The Cisco MDS 9000 Family IP services module integrates seamlessly into the Cisco MDS 9000 Family
of Multilayer Directors and Fabric Switches. Traffic can be routed between any IP storage port and any
other port on a Cisco MDS 9000 Family switch. The Cisco MDS 9000 Family IP Storage Services
Module supports the full range of services available on other MDS 9000 Family Switching Modules
including VSANs, security, and traffic management. It uses widely known IP to cost-effectively connect
to more servers and more locations over greater distances than previously possible. It delivers both Fibre
Channel over IP (FCIP) and iSCSI IP storage services and is configurable on a port-by-port basis.

Call Home

The Call Home feature detects switch failures and sends alerts along with relevant failure information.
These alerts are sent through E-mail to a user-specified customer center.

QoS and Congestion Control

Switches in the Cisco MDS 9000 Family provide priority queuing and flow control services.

FCIP highlights
Simplifies data protection and business continuance strategies by enabling backup, remote
–
replication, and disaster recovery over WAN distances using open-standard FCIP tunneling.
Improves utilization of WAN resources for backup and replication by tunneling up to 3 virtual
–
Inter Switch Links (ISLs) on a single Gigabit Ethernet port.
Reduces SAN complexity by eliminating the need to deploy and manage a separate remote
–
connectivity platform.
Preserves Cisco MDS 9000 Family enhanced capabilities including VSANs, advanced traffic
–
management, and security across remote connections.
iSCSI highlights
Extends the benefits of Fibre Channel SAN-based storage to IP-enabled servers at a lower cost
–
point than possible using Fibre Channel interconnect alone.
Increases storage utilization and availability through consolidation of IP and Fibre Channel
–
block storage.
Transparent operation preserves the functionality of legacy storage applications such as zoning
–
tools.
Extending the Benefits of Fibre Channel SANs
–
The Quality of service (QoS) feature has the following advantages:
Provides relative bandwidth guarantee to application traffic.
–
Controls latency experienced by application traffic.
–
Prioritizes one application over another (for example, prioritizing transactional traffic over bulk
–
traffic) through bandwidth and latency differentiation.
