Riverbed SteelHead CXA-01555-B010 WAN Optimization Appliance, 100 Mbps QoS Bandwidth, 12-Port: This is a Riverbed SteelHead CX-series rack-mount WAN optimization appliance, model CXA-01555-B010 — the 1555 chassis class with the B010 bandwidth/feature SKU. MPN CXA-01555-B010. This is a dedicated WAN optimization device, not a generic firewall, router, or load balancer. Note: the inventory SKU prefix RIVERBEND is a transcription of the brand RIVERBED. This is a refurbished unit, fully tested.
Engineering Context
The SteelHead CX-1555-B010 is rated at 50 MB optimized throughput, up to 3,000 optimized TCP connections, and 100 Mbps of QoS-managed WAN bandwidth. Storage is 2 TB raw with 400 GB of data store capacity used by Riverbed's RiOS scalable data referencing for byte-level deduplication of WAN traffic. RAM is 8 GB. The chassis provides 4 hot-swappable drive bays and 4 PCIe expansion slots. Maximum bypass-port count on this chassis is 12, supporting in-path or out-of-path deployment with hardware bypass for failover.
Deployment & Use Cases
Branch-office WAN acceleration for CIFS/SMB file shares, MAPI/Exchange email, and HTTP/HTTPS web traffic. Data center hub appliance terminating optimized tunnels from many remote SteelHead clients. QoS shaping on a 100 Mbps WAN circuit where prioritization between voice, replication, and bulk transfer is required. Lab and pre-production environments validating Riverbed RiOS optimization policies before deploying to a production fleet.

Compatibility & Hard Constraints
Requires Riverbed RiOS software licensing tied to the appliance serial; verify license transferability with Riverbed before relying on production support, as transfer eligibility depends on the unit's prior registration. This is a WAN optimization appliance, not a stateful firewall — it should be deployed in conjunction with, not in place of, a perimeter firewall. Maximum specified WAN throughput on this -B010 SKU is 100 Mbps; deployments exceeding 100 Mbps require a higher-class SteelHead model. Riverbed has migrated SteelHead CX series to the SteelHead 7050 family in current generations; the CXA-01555 is a previous-generation chassis suitable for refresh-replacement, lab, or non-critical roles.
