MCH/IOH PCI Express ports might help avoid the 2. GB/s DMI interface becoming a bottleneck. This is only likely to be an issue for those building raid / zfs based around SSDs and producing throughput greater than 1. GB/s. 1. 7 Aug 2. UTCGSnyderwrote: First- rate writeup, Marc - thanks for working on this. I wish I'd seen it a week ago before I started slogging through all of these issues on my own. VMware and QLogic provide drivers for various QLogic Fibre Channel Adapters, Converged Network Adapters, iSCSI and Intelligent Ethernet Adapters. Unfortunately, Open. Solaris (and I assume, Solaris) doesn't yet (as of August, 2. Marvell 8. 8SE9. 12x series, even though they are billed as being AHCI compliant. Several users have confirmed that the OS sees the card but not the attached drives. Currently I'm using a card based on a Silicon Image 3. SATA ports on the Intel ICH7 motherboard. There is also an Open. Solaris driver issue that produces frequent hesitations in the data flow, not to mention the fact that Open. Solaris doesn't support this controller's NCQ. I think I'm going to give the Super. Micro ACOC- USAS- L8i a try. Aug 2. 01. 0 0. 9: 2. UTCmrbwrote: Thanks GSnyder. Post updated. Back to the question of software vs. RAID, Intel acknowledges too that software RAID can be faster: http: //www. Sep 2. 01. 0 0. 3: 3.

LSI now has a 1. 6 port internal card for around $4. LSI SAS 9. 20. 1- 1. This card will work nicely in a 2. I plan on getting this card to create a huge backup server using ZFS and Open.

Note that the gen.

Nov 2. 01. 0 2. 3: 2. UTCBrianwrote: I'm trying to understand how many drives I can connect to an ESATA port on a motherboard that says it is using the JMicron JMB3. I vaguely understand that port multiplier technology is involved, but JMicron's site says this chip "supports" port multiplier technology and I can't tell if that's the same thing as saying it includes/implements such functionality or whether the enclosure I buy needs to have some sort of additional controller. Their site says that this chip "Supports 2- port 3. Gbps SATA II interface and Supports two independent SATA II channels (separate logic and FIFO)" and this motherboard has two ESATA ports, so I think each port is driven by this chip. Oracle Solaris 11.3 Release Notes l Describes the important installation issues, update issues, and runtime issues that you might need to consider before. Oracle acquired Sun Microsystems in 2010, and since that time Oracle's hardware and software engineers have worked side-by-side to build fully integrated systems and. I just want to know if I can connect 4 drives to one port, two drives to each port, or only one drive to each port. The hard drive enclosures that require your mobo to support port multiplier technology are a lot cheaper, so I'd prefer to get one of those if it would work. Any ideas? 0. 2 Dec 2. UTCmrbwrote: This wording means the motherboard is not using a port multiplier, but that it does support an (optional) port multiplier downstream (eg. However you do not _need_ to use a port multiplier. The chip JMB3. 62 supports 2 sata ports. One of them is your e. SATA port, the other one is either internal or unused (the pins of the chip are not wired). Dec 2. 01. 0 0. 5: 3. UTCdomielwrote: Just wondering if you (or any of your readers) know anything about the intel RS2. WC0. 80. I'm guessing it's equivalent to the LSI SAS2.

WC0. 80 is definitely based on the LSI SAS2. It looks like it supports JBOD - - that's my gut feeling based on Intel presenting it as an "entry- level RAID" controller. Dec 2. 01. 0 0. 3: 3.

I find very little information about PCIe Promise SATA/SAS cards. It is unclear whether they are well supported by Linux/Solaris/BSD and which chips the card use.
