Q
What is a Dell Storage Compatible SFP28 transceiver?
A
A Dell Storage Compatible SFP28 transceiver is a 25Gb/s optical module designed for Dell storage arrays and switches to deliver high-speed, low-latency connectivity in data center environments.
Q
Which Dell storage arrays and switches support SFP28 modules?
A
Most Dell EMC PowerStore, PowerMax and XtremIO arrays, as well as Dell Networking Z and S series switches, natively support SFP28 for 25Gb/s uplinks and fabric acceleration.
Q
What cable types work with Dell Storage Compatible SFP28?
A
Dell Storage Compatible SFP28 modules support single-mode fiber (SMF), multi-mode fiber (MMF) and DAC/AOC copper assemblies depending on the specific model selected.
Q
How far can Dell SFP28 modules transmit data?
A
Dell SFP28 transceivers offer reach options ranging from 100 meters over OM4 multimode fiber to 10 kilometers over single-mode fiber, depending on the module type.
Q
Are Dell Storage Compatible SFP28 modules hot-swappable?
A
Yes, Dell SFP28 modules are hot-swappable, allowing insertion or removal without powering down the host device, minimizing network downtime during maintenance.
Q
Is Dell SFP28 backward compatible with SFP+ ports?
A
No, Dell SFP28 modules operate at 25Gb/s and are not supported in legacy 10Gb/s SFP+ ports; use SFP+-rated optics for 10Gb/s connectivity.
Q
How do I install a Dell Storage Compatible SFP28 module?
A
To install, power down the port if possible, insert the SFP28 transceiver into the SFP28 slot until it clicks, then connect the fiber or copper cable and verify link status in the interface configuration.
Q
Can Dell SFP28 modules work with non-Dell switches and arrays?
A
Many Dell Storage Compatible SFP28 modules are designed for multi-vendor interoperability, but you should verify vendor compatibility lists and firmware versions before deployment.
Q
What wavelength do Dell SFP28 optics use?
A
Dell SFP28 optics use standardized wavelengths such as 850 nm for short-reach multimode, 1310 nm for 10 km single-mode, and 1550 nm for extended-reach applications.
Q
What is the power consumption of Dell Storage Compatible SFP28?
A
Typical power consumption for Dell SFP28 modules is between 1.0W and 1.5W, depending on the reach and form-factor of the optical or copper variant.
Q
How do I troubleshoot link-up issues with Dell SFP28?
A
First check fiber cleanliness and connector seating, verify module compatibility and firmware, then review switch logs for errors and replace the transceiver if errors persist.
Q
What industry standards do Dell SFP28 modules comply with?
A
Dell Storage Compatible SFP28 transceivers comply with IEEE 802.3by for 25Gb Ethernet, SFF-8402, SFF-8401 and MSA specifications for multi-source interoperability.
Q
How do I choose the right Dell SFP28 module for my Dell storage?
A
Select based on required link speed (25Gb), distance, fiber type, and port compatibility by matching Dell SKU part numbers to your storage array or switch model.
Q
What is the MTBF of Dell Storage Compatible SFP28?
A
Dell SFP28 transceivers have a typical Mean Time Between Failures (MTBF) of over 1 million hours based on accelerated stress testing under industry standards.
Q
Can Dell SFP28 support breakout cables on QSFP28 ports?
A
Yes, you can use a QSFP28-to-4×SFP28 breakout cable on compatible Dell QSFP28 ports to split a 100Gb link into four independent 25Gb channels.
Q
Do Dell SFP28 modules require firmware updates?
A
Dell Storage Compatible SFP28 modules generally operate without user-applied firmware, but host devices may require the latest OS or driver updates for optimal performance.
Q
Where can I purchase genuine Dell Storage Compatible SFP28?
A
You can order genuine Dell SFP28 modules through Dell’s online store, authorized resellers or certified partners to ensure compatibility and warranty coverage.
