When the Norco RPC-4020 server case first arrived in the summer of 2008, it was a pivotal device that brought the idea of "a lot of storage for little cost" within reach for many people. The HP SAS Expander is another game changing device- combine it with a low-cost RAID or HBA adapter and you've got 32 ports of harddisk connectivity for only a few hundred dollars.
Overview: The HP SAS Expander is based on the next-gen PMC Sierra PM8005 SAS-2 chip which features 36 x 6Gbps ports and 6G/3G multiplexing, SAS 2.0 zoning, self-configuration, table-to-table routing, and an integrated MIPS processor for SES and enclosure management support.

[#FF2A00]FAQ[/#FF2A00]
Q: What's so special about this card?
A: The PM8005 chip has proven to be more compatible in more HBA/Drive configurations than previous generation expanders like the LSI-based Chenbro CK series. While HP intended this card be used in their HP Proliant servers, the card is driverless and essentially "universal" and can be used with non-HP branded RAID and non-RAID HBA cards. What's unique is the ability to connect 32 drives at a relatively low cost, when combined with a low cost 4 or 8 port RAID or non-RAID HBA.
Q: Where do I purchase this card and why do[#00AA55] I want the green card[/#00AA55] and [#FFC600]NOT the yellow card[/#FFC600]?
A: There are multiple hardware versions of this card, available from Amazon, ebay, etc. The yellow PCB version is the oldest hardware revision, has a smaller heatsink, and CANNOT be flash upgraded from its v.0.20. The green PCB cards are the newer hardware revision. I've bought green PCB cards from ebay and they came with firmware v1.00. I've bought a card from Amazon and it came with v1.52. Shipping firmware will depend how old your source's inventory is. To work correctly at 3Gbps with newer SATA2 drives you need firmware v1.52 firmware or higher. Click thumbnail to see a side-by-side of both cards. DO NOT buy the yellow PCB card, it is useless and will not work.

Q: How do I install the HP SAS Expander and what are the power requirements?
A: The card needs an x4 PCIe slot on a motherboard and draws 11 watts of power. The card doesn't require software drivers, it is invisible to the operating system and motherboard. A common dilemma is people needing to use this card in an empty chassis like a Norco RPC-4220 to create a JBOD enclosure. Some people have resorted to using an old motherboard serve as a power source and ON/OFF switch for the chassis - such a solution costs significantly less than buying a prefab expander chassis. Unfortunately this card has no external 4-pin Molex power connector like the Intel RES2SV240, another highly recommended SAS expander card, but in exchange you're getting 36 ports instead of 24 on the Intel.
Q: How do I connect harddisks to the HP SAS Expander?
A: There are 9 ports total which can connect four harddisks each. The external SFF-8088 port is Port #1. The internal SFF-8087 are Port #2 through Port #9. I recommend populating drives beginning with internal Port #2. To uplink the expander to your RAID/HBA, connect to Port #8 on the expander with an SFF-8087 cable from your RAID/HBA. If your RAID/HBA has an external SFF-8088 connector, connect to Port #1 on the expander with an external SFF-8088 cable.
Q: How many cables do I need to connect the HP SAS expander to my RAID or HBA card?
A: You only need 1. However some newer SAS-2 based RAID and HBA cards support link aggregation with two SFF-8087 cables connected between the RAID/HBA and ports #8 and #9 on the expander, effectively doubling bandwidth.
Q: How many harddisks can you attach to the HP SAS expander?
A: Up to 32. I've stress tested various configurations including a RAID6 array with 32 x 1Tb drives and had no issues.

KNOWN ISSUES
1) HP SAS Expander will only negotiate SATA-III harddisks at 3G (SATA300) even though it is capable of 6G (SATA600). It does however negotiate SAS disks at 6G.
2) In combination with an Areca 1880 series controller, certain Western Digital harddisks (Velociraptor, etc) when configured in a raid volume will cause Areca boot-time firmware initialization to hang when connected to the HP SAS Expander. This is an issue Areca needs to resolve, but something to be aware of.
