NETGEAR 24x10Gig , L2+, Managed switch, XSM7224S

* Purposely built for virtualization and distributed LACP * Top-of-Rack: stackable solution for Active-Active server teaming * Aggregation and Core scalability with L3 licensing The NETGEAR ProSafe 10 Gigabit Stackable Managed Switch, XSM7224S, allows for a flexible top-of-rack infrastructure. All 24 ports of 10 Gigabit SFP+ interfaces are Gigabit/10 Gigabit capable and deliver wired speed performance with ultra low latency. Four shared 10GBase-T interfaces broaden 10 Gigabit connectivity with auto-sensing RJ45. Local/distant stacking provides versatile 10 Gigabit deployment possibilities, such as Distributed (LACP) Aggregation for virtualized servers and storage. Enterprise-class L2+ Combining superior resiliency, enterprise-class security, and non-blocking performance, the XSM7224S offers a full set of Layer 2 management features, as well as Layer 2+ (Layer 3 lite – IPv4 routing) with unsurpassed affordability. Together with VLAN routing, voice-class prioritization, and chassis-like stacking, the XSM7224S can be deployed as a data center Top-of-Rack switch, or closer to the core of small and medium businesses’ growing networks, as a distribution layer 10 Gigabit Ethernet aggregation switch. L3 Scalability (available in Q1 2011) The Layer 3 upgrade license XSM7224L unlocks the IPv4/IPv6 dynamic routing capabilities of the XSM7224S. Purposely built for Enterprise networks and core / aggregation layers of SMB networks, an L3 upgraded XSM7224S provides advanced routing protocols such as OSPF, VRRP, and multicast for converged applications. Data Center Availability The NETGEAR Stackable, Managed 10 Gigabit Switch XSM7224S comes with a removable power module for the main power supply with a second internal redundant power supply available as an option. Two removable fan trays increase the availability of the system, providing front-to-back cooling airflow for best compatibility with data center hot aisle / cold aisle airflow patterns. Like all NETGEAR ProSafe Managed Switches, the XSM7224S is backed by the NETGEAR ProSafe Lifetime Warranty.
