Virtualization VMready with VI API and pre-configuration of VM OUI MACs VMready provides Virtual Machine-aware networking for dynamic Virtual Machine mobility using any standard hypervisor. This integration ensures that essential network personality characteristics (VLAN, QoS and ACLs) automatically follow Virtual Machines (VMs) as they move dynamically from server to server across an enterprise datacenter network. VMready is capable of supporting Edge Virtual Bridging (EVB) as defined by IEEE 802.1Qbg.
Distributed vSwitch and VMware Supports the IBM Distributed Virtual Switch 5000V and VMware vSphere 5.0
Unified Fabric Port Provides a cost-effective way to maximize the benefits of client’s 10 Gb (and higher) physical NICs by letting them allocate, share and dynamically control their network throughput according to their needs. UFP separates server bandwidth into multiple secure channels to serve different applications and traffic types.
It dynamically allocates bandwidth as traffic needs change. UFP also works with converged enhanced Ethernet, Fibre Channel over Ethernet and FIP snooping in standalone (non-stacked) mode.*
vNIC management through SNMP applications vNIC carves up a dual-port 10 G adapter into eight virtual NICs (vNICs) and creates dedicated virtual pipes between the adapter and the switch. vNIC functionality provides the ability to dynamically allocate bandwidth per vNIC in increments of 100 Mb.
Management features FTP
USB boot  
SYSLOG configuration tracking Logging of all configuration changes include what was changed and the user making the change.
Stacking Stacking allows multiple switches to behave as a single device, sharing a single IP address utilizing a single configuration file. Stacking allows servers with multiple NICs to utilize LACP to load balance the traffic across their network interfaces and maintain the redundancy of multiple network devices upstream.
LLDP stacking LLDP is a standards based protocol used by vendors to advertise and discover the identity and capabilities of other devices on the local network. Extending the stacking feature to support LLDP means the stack can now advertise itself to others and be identified as a single unit with the combined features and port capabilities of the stack.
Hybrid Ethernet/Fibre Channel stacking  
Local preference for stacking Local preference in stacking provides a configuration option where the user can specify the local ports as a preferred path over the shared stacking link.
Logical switch partitioning (SPAR) SPAR provides the ability to create logical Layer 2 switch partitions within a single physical switch. This provides dedicated port isolation to different networks without incurring the cost of additional hardware.
