A quick online search tells me that Solaris still doesn’t seem to support it. (I added the card, thanks). Mrb wrote: The AOC-SAS2LP-MV2 is a new card based on the (same old) 88SE9480 controller that was already in my list, shown as not supported by Solaris.

You should try a PCIe 2. Title updated to “32 to 2 ports” 🙂 Thanks rektide, and Royce. 0 on your server but that doesn’t matter as the the 3 vs 6 Gbps SATA/SAS link speed is completely independent of the PCIe speed. It will fall back to 1. To Jim: don’t bother with the aging PCI-X tech. I have always wanted cards to use PCIe switching technology to increase the number of chips & ports. HighPoint is finally the first to do it. Mrb wrote: Wow these new RocketRAID 27xx are sick.

The purpose of comparing the two designs is merely to show how much performance can be gained from the new design. We will be posting benchmark results in an effort to explain the performance difference between the ZFSBuild2012 design and the ZFSBuild2010 design. We used the same benchmark tools that we ran back in 2010, and we even used the same blade for running the benchmarks, so the benchmarks we will post comparing the two designs are a true apples to apples test. Over the past two years, we learned a lot of things about designing better ZFS based SANs and the underlying hardware got a lot faster. It is probably not a spoiler to let everybody know that the ZFSBuild2012 design is much faster than the ZFSBuild2010 design.

I assumed for all PCIe controllers that only 60-70% of the maximum theoretical PCIe throughput can be achieved, and for all PCI-X controllers that only 80% of the maximum theoretical PCI-X throughput can be achieved on this bus. Here is my list of non-RAID SATA/SAS controllers, from 16-port to 2-port controllers, with the kernel driver used to support them under Linux, and Solaris. There is also limited information on FreeBSD support. As of May 2010, modern disks can easily reach 120-130MB/s of sequential throughput at the beginning of the platter, so avoid controllers with a throughput of less than 150MB/s/port if you want to reduce the possibility of bottlenecks to zero. The MB/s/port number in square brackets indicates the maximum practical throughput that can be expected from each SATA port, assuming concurrent I/O on all ports, given the bottleneck of the host link or bus (PCIe or PCI-X). I focused on native PCIe controllers only, with very few PCI-X (actually only 1 very popular: 88SX6081). These assumptions concur with what I have seen in real world benchmarks assuming a Max_Payload_Size setting of either 128 or 256 bytes for PCIe (a common default value), and a more or less default PCI latency timer setting for PCI-X.

The FreeBSD Project is run by around 500 committers, or developers who have commit access to the master source code repositories and can develop, debug or enhance any part of the system. A number of responsibilities are officially assigned to other development teams by the FreeBSD Core Team, for example, responsibility for managing the ports collection is delegated to the Ports Management Team. Most of the developers are volunteers and few developers are paid by some companies. [15] There are several kinds of committers, including source committers (base operating system), doc committers (documentation and web site authors) and ports (third party application porting and infrastructure). Every two years the FreeBSD committers select a 9-member FreeBSD Core Team who are responsible for overall project direction, setting and enforcing project rules and approving new commiters, or the granting of SVN commit access.

Currently ZFS on FreeBSD is only available for i386 and amd64 architectures. Mostly because of missing atomic operations that are implemented in assembler.

[95] Jan Koum himself is a FreeBSD user since the late 1990s and WhatsApp uses FreeBSD on its servers. In December 2016, Jan Koum donated another 500 thousand dollars. In November 2014, the FreeBSD Foundation received 1 million USD donation from Jan Koum, Co-Founder and CEO of WhatsApp, – the largest single donation to the Foundation since its inception.

Consequently, many ZFS and Linux MD RAID users, such as me, look for non-RAID controllers that are simply reliable, fast, cheap, and otherwise come with no bells and whistles. Most motherboards have up to 4 or 6 onboard ports (be sure to always enable AHCI mode in the BIOS as it is the best designed hardware interface that a chip can present to the OS to enable maximum performance), but for more than 4 or 6 disks, there are surprisingly not that many choices of controllers. Over the years, I have spent quite some time on the controllers manufacturers’ websites, the LKML, linux-ide and ZFS mailing lists, and have established a list of SATA/SAS controllers that are ideal for ZFS or Linux MD RAID. I also included links to online retailers because some of these controllers are not that easy to find online.

ZFS is commonly used by data hoarders, NAS lovers, and other geeks who prefer to put their trust in a redundant storage system of their own rather than the cloud.

I prefer to have an actual /home filesystem, and make a compatibility link from /usr, which is the reverse of the default layout produced by the installer. The policy of creating home directories under /usr/home dates back to the days when disks were much smaller, and doesn’t really make sense nowadays.
