Datasheet
When running the Dell Networking OS9, Active Fabric™
implementation for large deployments in conjunction with the
Dell Z Series, creating a flat, two-tier, nonblocking 10/40GbE
data center network design
• Small-scale Active Fabric implementation via the S4048-
ON switch in leaf and spine along with S Series 1/10GbE
ToR switches enabling cost-effective aggregation of
10/40GbE uplinks
• iSCSI storage deployment including DCB converged
lossless transactions
• High-performance SDN/OpenFlow 1.33 enabled
with ability to inter-operate with industry standard
OpenFlow controllers
• As a high speed VXLAN Layer 2 Gateway that connects
the hypervisor based ovelray networks with non-
virtualized infrastructure
Key features - General
• 48 dual-speed 1/10GbE (SFP+) ports and six 40GbE (QSFP+)
uplinks (totaling 72 10GbE ports with breakout cables) with
OS support
• 1.44Tbps (full-duplex) non-blocking switching fabric delivers
line-rate performance under full load with sub 700ns latency
• I/O panel to PSU airflow or PSU to I/O panel airflow
• Supports the open source ONIE for zero-touch
• installation of alternate network operating systems
• Redundant, hot-swappable power supplies and fans
• Low power consumption
• Support for multi-tenancy lilke VXLAN and NVGRE in hardware
Key features with Dell Networking OS9
Scalable L2 and L3 Ethernet switching with QoS and a full
complement of standards-based IPv4 and IPv6 features,
including OSPF, BGP and PBR (Policy Based Routing) support
• VRF-lite enables sharing of networking infrastructure and
provides L3 trac isolation across tenants
• Increase VM Mobility region by stretching L2 VLAN within or
across two DCs with unique VLT capabilities like Routed VLT,
VLT Proxy Gateway
• VXLAN gateway functionality support for bridging the
nonvirtualized and the virtualized overlay networks with line
rate performance.
• Embedded Open Automation Framework adding automated
configuration and provisioning capabilities to simplify the
management of network environments. Supports Puppet
agent for DevOps
• Modular Dell Networking OS software delivers inherent stability
as well as enhanced monitoring and serviceability functions.
• Enhanced mirroring capabilities including 1:4 local mirroring,
Remote Port Mirroring (RPM), and Encapsulated Remote Port
Mirroring (ERPM). Rate shaping combined with flow based
mirroring enables the user to analyze fine grained flows
• Jumbo frame support for large data transfers
• 128 link aggregation groups with up to 16 members per group,
using enhanced hashing
• Converged network support for DCB, with priority flow control
(802.1Qbb), ETS (802.1Qaz), DCBx and iSCSI TLV support
Fastboot feature enables min-loss software upgrade on a
standalone S4048-ON without VLT/stacking
• S4048-ON supports Routable RoCE to enable
convergence of compute and storage on Active Fabric
• User port stacking support for up to six units
