The HPE C8R25B is a 10Gb iSCSI SFP+ transceiver option for HPE MSA 2040 storage arrays, enabling high-speed Ethernet block storage connectivity from the array’s converged host ports. For organisations that run their SAN over 10Gb Ethernet rather than Fibre Channel, the C8R25B is the qualified optic that lights up MSA controller ports for iSCSI traffic, and Euroland IT Store stocks it new and refurbished with fast UK delivery.
MSA 2040 controllers use flexible host ports that can operate in different personalities, and populating them with the correct qualified optic is essential for supported operation. The C8R25B installs into a controller SFP+ cage, presents LC fibre connectivity for 10Gb Ethernet transport, and is hot-pluggable, allowing ports to be added or optics exchanged without disrupting the partner controller. This makes it the standard choice when commissioning an iSCSI-connected MSA 2040, expanding host connectivity, or replacing a failed port optic.
The appeal of 10Gb iSCSI is practical: it lets IT teams deliver shared block storage over the Ethernet switching they already own, avoiding the cost of a dedicated Fibre Channel fabric. With a C8R25B transceiver in each active host port, an MSA 2040 can serve virtualisation clusters, file servers and backup infrastructure at full 10Gb line rate with proper multipath redundancy across both controllers.
As the MSA 2040 platform matures, this option can be hard to source quickly through distribution. Euroland IT Store, a trusted UK supplier of storage spares and HPE parts, keeps tested C8R25B stock available at prices substantially below original list, with matched sets for dual-controller builds. Ask our team for a quote, compatibility confirmation against your controller configuration, or volume pricing for multiple arrays.
Fitting qualified C8R25B optics gives your MSA 2040 clean, full-rate 10Gb iSCSI links with the stable low latency that virtual machine datastores and database volumes need. Because the optic is matched to the platform, you avoid the negotiation faults and unsupported-configuration risks that come with generic 10Gb modules in storage controllers, problems that are disproportionately painful when they surface on a production array. If your estate mixes host protocols, the Fibre Channel sibling for the same converged ports is the HPE C8R24B MSA 16Gb FC SFP+ Transceiver.
Sourcing from Euroland IT Store makes the economics work. Tested refurbished C8R25B units cost far less than list price, so populating all four host ports across both controllers, or holding a shelf spare, is an easy decision rather than a budget battle. New stock is available where procurement rules require it.
The wider benefit is uptime: with hot-pluggable optics and a spare on site, a failed transceiver is a minutes-long fix that never touches your multipathed workloads. For the network side of an iSCSI design, the HPE JH390A FlexFabric 5940 Switch is a 10Gb-capable data centre switch well suited to storage traffic, and the HPE P28787-B21 X710 10Gb SFP+ Adapter connects hosts into the same fabric. You will find the full optic range in our server and storage transceivers category. Add fast UK dispatch and expert compatibility checks, and keeping an iSCSI MSA estate healthy becomes straightforward and inexpensive.
