Hello   It would be 1.2GB/s. The PERC 5e has two connectors for two different channels. Each of those connectors consists of 4x300MB/s ports, so each channel is capable of 1.2GB/s. That is theoretical. You will not actually be able to hit that number as there is overhead to consider. The document states 80% is about the max achievable, so that would put you at around 960MB/s.   These are logical ports. That connector is for a channel. The channel consists of 4 logical ports.   Yes, that is basically what it means. Thanks
Hello, I've read many articles about PERC 5/E and after last article from Dell's website I am totally confused. I do not have much experience with these things.  [URL] My question is: If I daisy chain 3x MD1000 and connect them to one port, what is the maximum throughput? How could I hit 1GBps? Is 300MBps maximum per port (wide port?) or per PERC 5/E? How could I go above this? (on link provided at the top) "The PERC 5 is connected to the server through an x8 PCI Express slot rated at 2 GB/sec (although some systems may utilize an x4 PCI Express slot, rated at 1 GB/sec). The PERC 5 has two SAS wide ports to connect the controller to expanders. Each wide port is a combination of four SAS ports rated at 300 MB/sec each, providing a throughput of 1,200 MB/sec per expander, or 2,400 MB/sec total." I understand wide ports, but what do they exactly mean by "four SAS ports" ? Do they mean that each physical port is somehow 4 SAS ports? So it has dual x4 SAS? Then each port has throughput of 1.2GBps? Did I understand it correctly? Please explain someone simply. Thanks in advance!
What is the maximum throughput of PERC 5/E + MD1000? Confused in calculations.
