BES-53248 Ethernet Storage Switch for Lenovo
Product Guide
The BES-53248 Ethernet Storage Switch for Lenovo is an IP SAN storage switch that is designed and
optimized to provide dedicated Ethernet storage fabric, including storage clustering in the data center and
between the local and remote sites, and it offers 10/25/40/100 Gb Ethernet connectivity with "pay-as-you-
grow" scalability. The switch delivers line-rate, high-bandwidth lossless switching that keeps storage data
traffic moving without delays, while the hot-swap redundant power supplies and system fans (along with
numerous high-availability software features) help provide high availability for business-critical traffic.
Running the Broadcom industry-leading Enterprise Fabric Operating System (EFOS), the BES-53248
Ethernet Storage Switches for Lenovo deliver production-ready networking software customized for IP
storage solutions with advanced networking features and protocols required in the modern storage
infrastructure for data center applications.
The BES-53248 Ethernet Storage Switch for Lenovo has 48x SFP28/SFP+ ports that support 10 GbE SFP+
and 25 GbE SFP28 optical transceivers and direct attach copper (DAC) cables. The switch also offers
8x QSFP28/QSFP+ ports that support 40 GbE QSFP+ and 100 GbE QSFP28 optical transceivers and DAC
cables.
The BES-53248 Ethernet Storage Switches for Lenovo are ideally suited for enterprises of various sizes with
all flash and NVMe IP Ethernet storage environments, as well as clustered storage deployments.

Key features
The BES-53248 Ethernet Storage Switch for Lenovo offers the following features and benefits:
Provides validated, certified network interconnect for deploying clustered storage and MetroCluster IP
configurations with the Lenovo ThinkSystem DM Series storage arrays.
Offers high scalability in a dense, 1U network switch with 48x SFP28/SFP+ ports and 8x
QSFP28/QSFP+ ports to support IP storage clustering, iSCSI, NVMe over RoCE, and flash-based
storage environments.
Enables cost-effective “pay-as-you-grow” scalability from 18 to 56 ports with Ports On Demand
(POD).
Increases performance and flexibility for demanding storage workloads with a combination of ultra-
low latency and non-blocking, line-rate switching and support for 10/25/40/100 Gbps Ethernet links.
Accelerates communications with lower latency across clustered applications and storage arrays with
RDMA over Converged Ethernet (RoCE) and iWARP.
Optimizes IP storage fabric behavior and ensures sufficient bandwidth for mission-critical applications
with congestion management and advanced traffic scheduling.
Simplifies deployment of large-scale environments by enabling a switch to automatically provision
itself using the resources available on the network, without manual intervention, with Zero Touch
Provisioning (ZTP) and AutoInstall.
Supplies a rich set of standard features at no extra cost, including scalability and
performance, availability and redundancy, virtual local area networks, security, quality of service,
IPv4/IPv6 routing and host management, virtualization, data center fabric, monitoring, and
management.
Runs Enterprise Fabric OS, which deliver production-ready networking software customized for IP
storage solutions with advanced networking features and protocols required in the modern storage
infrastructure for data center applications.
Maximizes resiliency with redundant hot-swap system fans and power supplies, along with numerous
high-availability software features.
Allows switch management integration into third-party management applications by supporting the
REpresentational State Transfer (REST) Application Program Interface (API).
