4.1(1b) Features
|
Description
|
New 8-Gbps Performance Fibre Channel Module Support
|
Cisco NX-OS Release 4.1(1b) supports the following new switch hardware platforms and modules:
• 48-port 8-Gbps Fibre Channel Switching Module
•24-port 8-Gbps Fibre Channel Switching Module
•4/44-port 8-Gbps Host-Optimized Fibre Channel Switching Module
|
Call Home Delayed Traps Feature
|
Cisco NX-OS Release 4.1(1b) provides the ability to generate a delayed trap so that the number of generated email messages is reduced. This method filters server reboots and avoids generating unnecessary Call Home email messages.
|
Smart Call Home Enhancement
|
Cisco NX-OS Software offers a Call Home feature for proactive fault management. Beginning with NX-OS Release 4.1(1b), all MDS switches are capable of sending notifications using HTTPS and can be integrated with Cisco Smart Call Home software
|
SANTap Enhancements
|
SANTap is now supported on the MSM-18/4 module and the MDS 9222i switch. Third party applications like Recoverpoint and NetApp ReplicatorX are now able to take advantage of Generation 2 line cards.
|
IPv6 Support
|
Beginning with NX-OS Release 4.1(1b), IPv6 is supported on the MSM-18/4 module and the MDS 9222i switch.
|
NPV Traffic Management
|
Cisco NX-OS Software supports industry-standard N-port identifier virtualization (NPIV), which allows multiple N-port fabric logins concurrently on a single physical Fibre Channel link. HBAs that support NPIV can help improve SAN security by enabling zoning and port security to be configured independently for each virtual machine (OS partition) on a host. In addition to being useful for server connections, NPIV is beneficial for connectivity between core and edge SAN switches.
|
CFS Distribution Using Static List
|
Cisco NX-OS Release 4.1(1b), combines the Cisco Fabric Services (CFS) static list feature with the Fabric Manager's NPV device discovery feature and provides a near-seamless user experience of managing NPV devices using CFS.
|
Cisco Data Mobility Manager Enhancements
|
Beginning with NX-0S Release 4.1(1b), the Cisco MDS Data Mobility Manager (DMM) application is supported on the Cisco MDS 18/4-Port Multiservice Module. DMM is supported on the following cluster configurations:
•Sun Cluster
•HACMP(IBM)
•VCS (Veritas)
•MSCS (Microsoft)
|
Cisco Storage Media Encryption Enhancements
|
Beginning in NX-OS Release 4.1(1b), SME key management and provisioning are decoupled, which enables the KMC to be installed on a separate server from Fabric Manager Server (FMS). In addition, new roles are available to allow separate administration privileges. The new roles enable key management to be handled by a security group instead rather than the SAN administrators.
