Overview

The HP 498426-001 is an OEM Mini-SAS cable assembly designed for use within HP's server and workstation platforms. Mini-SAS (the SFF-8087 or SFF-8088 connector family) is the standard internal interface for Serial Attached SCSI storage controllers and backplanes — it carries four SAS or SATA lanes over a single connector, allowing a RAID controller or HBA to address multiple drives through one cable attachment point. In HP's server architecture, these cables route between the SAS/RAID controller and the drive backplane at a specific length and bend profile engineered for the chassis internal layout. Signal integrity in high-speed serial storage links is sensitive to cable length, impedance consistency, and connector quality — which is why HP uses validated OEM parts rather than generic aftermarket cables in their support documentation.

This cable exists for one primary purpose: maintaining or restoring a validated storage configuration in an HP server or workstation. System administrators performing preventive maintenance, field service engineers replacing components after a storage fault, or users rebuilding an HP server from parts — these are the buyers this part is built for. It is not a general-purpose Mini-SAS cable, and it should not be selected for non-HP builds where length, connector type, and routing requirements are unknown. Within its validated application, it represents the lowest-risk path to restoring original-spec storage connectivity. Buyers should confirm the part number against HP's service manual for their specific chassis model before ordering, as HP used multiple Mini-SAS cable part numbers across different server generations and configurations.

Pros & Cons

👍 Pros

OEM HP part number (498426-001) ensures validated signal integrity for HP server and workstation chassis where generic aftermarket cables introduce impedance and length variables
Mini-SAS connector format provides a 4-lane data path supporting multiple SAS/SATA drives through a single cable connection, consolidating backplane wiring
HP OEM validation means the cable has been tested for the specific bend radius, routing path, and thermal environment of HP's target chassis — reducing the risk of marginal signal conditions under sustained I/O load
Sourcing a genuine HP replacement part eliminates the guesswork of cross-referencing third-party equivalents for server maintenance or field service work

👎 Cons

No SAS generation or maximum signaling rate is specified in product documentation — buyers targeting SAS 12Gb/s (SAS-3) platforms must verify compatibility independently before purchase
The cable is validated for HP platforms specifically; using it in third-party server chassis is outside HP's tested configuration and may require confirming connector pinout and length compatibility
No connector type (SFF-8087 vs SFF-8087 to SFF-8482 breakout, etc.) is specified in the listing, which requires cross-referencing HP's service documentation to confirm the correct part for a given chassis
As a legacy OEM part, long-term availability is dependent on remaining stock — this is not a continuously manufactured commodity cable

Frequently Asked Questions

What does "Mini-SAS" mean, and what storage devices does this cable connect?

Mini-SAS (SFF-8087 or SFF-8088 connector format) is the standard internal or external interface for Serial Attached SCSI (SAS) storage devices and SAS/SATA expanders. This cable connects SAS HBAs (host bus adapters) or RAID controllers to drive backplanes, expanders, or SAS/SATA hard drives in server and workstation environments. Without the specific connector specs confirmed, assume it mates to HP's standard server backplane pinout.

Will this cable work in non-HP servers or workstations?

Mini-SAS connector form factors (SFF-8087/SFF-8088) are standardized, so the physical connector will fit any compatible Mini-SAS port. However, HP OEM cables are engineered and validated for specific HP server and workstation chassis — signal integrity, cable length, and bend radius are tuned to those platforms. Using it outside HP-validated hardware configurations is electrically possible but outside HP's tested support envelope.

What SAS generation (speed) does this cable support?

The product listing does not specify SAS generation. HP's server platforms from the era this part number originated support SAS 6Gb/s (SAS-2). If your backplane or HBA operates at SAS 12Gb/s (SAS-3), verify compatibility with HP's platform documentation before assuming this cable supports the higher signaling rate.

Is this cable a direct replacement for a failed cable in an existing HP server?

Yes — part number 498426-001 is an HP OEM replacement part. If your server originally shipped with this part number (identifiable on the original cable or in HP's service manual for your chassis), this is the correct like-for-like replacement. Substituting a different part number cable risks impedance mismatch or incorrect length for the chassis routing.

Does this cable carry both data and power, or data only?

Mini-SAS cables carry data signals only — not power. Drive power in SAS backplane configurations is supplied separately through the backplane's power connector from the server's PSU. This cable handles only the high-speed data path between the controller and the drives.
