something like the MINISAS Expander to provide

I bought some mini-sas to 4 port SATA cables today, but they didn't seem to work with the backplanes, the drives were not detected, but from a bit of research, I found that there are two types of cables, one which works with MINISAS on the host side, and SATA on the target side, and another which does SATA on the host side, and MINISAS Cable Assemblies adapters at the target side. I will search for the SATA (host) to Mini-SAS (target) cables.You can try Molex or Amphenol. These are a couple of the biggest connector and cable manufacturers. Molex is the company that came up with the MINISAS connectors and cable system. Digikey or Mouser may have cables? maybe? You are correct, most go from mini-sas host to SATA drive. You basically want pass though type cables. I do not know if Adaptec, 3ware, LSI, etc sell cables separately... but if they do, they may have 6.0 Gbps in order ones that are pass though... then again, this is not the normal configuration. A detailed forum about the HP expander is available here.I mentioned backplanes only because some have embedded expanders that allow them to accommodate more than 4 or 8 drives. You're probably not working with a system with a SAS backplane, so disregard that part and focus on expansion at the RAID card level.

The new cable systems being deployed are 10G cables enabled

This growth in the number of users globally did have a major impact on growth of technology  speeds in the core telecom backbone.  A decade back the telecom technology was limited to SDH, and speeds like SFP+ Plus 10G cables was the only capacity needed by carriers for their core backbone. Those days the number of internet users were much lesser even an enterprise would only need speeds from an E1 to STM-1 for internet or event for their private networks. So a small backbone was a direct result of the need those days. The 10G cables systems also laid during the phase supported these speeds only.

those designed to support rates in the range of 10G cable

10GBASE-T or IEEE 802.3an-2006 is a standard released in 2006 to provide 10 Gigabit/second connections over unshielded or shielded twisted pair cables over distances up to 100m(330ft). The twisted pair cable is typically comprised of four twisted pairs of 10GBE XFP TO XFP COPPER 10G Cable under the same jacket, but divided into four individual quadrants separated by a plastic spine extended throughout the entire length of the cable.   Each of these physical form-factors is defined in a standards document know as a Multi-Source Agreement, or MSA. Optical Transceivers types can be generally grouped into those supporting transmission speeds on the order of 1Gbps and those designed to support rates in the range of 10G cable. Optical transceivers form factors associated with 10Gbps transmission are: XFP, X2, XENPAK and SFP+.Some manufacturers of cable are able to achieve the 10G cable with unshielded twisted pairs, while other manufacturers construct their cable with twisted pairs wrapped with a foil shield.  CAT6 cable can be used in a 10G application, but there is a distance limitation of 55M (180ft).  To reach full 100M (330ft) length, CAT6A cable must be used to comply with 10G specifications.  CAT6A or CAT6 “Augmented” is the recommended cable for Ethernet standards 10G networking applications.Fiber Optic Transceiver module is a self-contained component that can both transmit and receive.

shield cables and a ground for the entire cable as well

Yesterday we did a cable pull. As an instrumentation worker this is probably as bad and as dirty as it gets. Most cables we pull are 18 gauge single pair. That means there is one black wire, one white wire, and a shield or ground cable. This is enclosed in a grey armored jacket. I’ve been involved in lots of those cables being pulled – not because I’m an apprentice but because it’s part of the job. The cables we had to pull today were 2 – 18 gauge 24 pair cables.Performance cables So inside the Grey cable there are 24 white wires, 24 black wires, 24 shield cables, and a ground for the entire cable as well.On this month’s Cable Talk, we discuss which cable components are critical and what the effects are of temperature fluctuations on sub-standard cables. We demonstrate how cable design, insulation and cable jacket materials collectively determine how effective a cable is in a  fast changing environment.

More than 210,000 users have watched a YouTube video of our data center operations team cabling a row of server racks in San Jose. More than 95 percent of the ratings left on the video are positive, and more than 160 comments have been posted in response. To some, those numbers probably tecnologicamente seem unbelievable, but to anyone who has ever cabled a data center rack or dealt with a poorly cabled data center rack, the time-lapse video is enthralling, and it seems to have catalyzed a healthy debate: At least a dozen comments on the video question/criticize how we organize and secure the cables on each of our server racks. It’s high time we addressed this “zip ties v. hook & loop (Velcro?)” cable bundling controversy.
