When you purchase through links on our site, we may earn an affiliate commission.The designation 8i stands for eight internal ports; 9200 is the new PCI Express 2.0 RAID-on-Chip generation; and RAID 6 is supported, which you can tell from the second part of the model number (60).LSI offers two internal SFF-8087 MiniSAS connectors, which host four SASSATA connections each.
The card is a low-profile design, which can also be deployed into compact 2U rackmount servers. Youll just have to bend the cables, as the connectors point upwards towards the top of the rackmount enclosure. Connectivity LSI totally redesigned its architecture to meet the demands of SAS600 environments. The RAID-on-Chip (RoC) architecture is built around an LSI SAS2108, which includes the x8 PCI Express 2.0 interface and SAS600 connectivity (6 Gbs). It can access a 512 MB DDR2-800 cache memory, and a battery backup module (BBU) was already installed on our samples (though LSI says that the BBU is still an optional component). The BBU prevents data loss in case of power failure while unwritten data is still in the controllers cache memory. Performance According to LSI, the controller itself supports a maximum read throughput of 2,875 MBs, and a peak write performance of 1,800 MBs. Knowing that were using two controllers and Windows software-based RAID to create an array across two controllers (and two different PCI Express links) were clearly on the safe side regarding bandwidth. ![]() We recommend looking at the controllers datasheet on the LSI Web site for more details. LSI MegaRAID 9210-8i The 9210-8i, aka Intel RS2BL080, offers the same number of SASSATA ports as the 9260-8i, and the PCB has exactly the same dimensions, but the product is somewhat different, and much simpler overall. It does not feature a powerful RAID-on-Chip solution with XOR acceleration for RAID 5 and RAID 6; it does not come with cache memory; and it doesnt feature a battery backup unit. However, that strip-down may be helpful in terms of throughput, as there is no processing unit and no cache memory that might be trying to improve performance while effectively limiting it in our scenario (as was the case with Adaptecs RAID 5805). We dont have much information on the 9210-8i, as it has not yet been officially released. It also utilizes PCI Express 2.0 (eight lanes) as one of the first products on the market, and it is ready for SAS600 drives as well. Creating a RAID 0 Stripeset on LSIs 9200-8i Cards The MegaRAID Storage Manager lists all LSI controllers and attached devices. Once a RAID array has been created, it will also list the volumes, called Virtual Drives. Creating an array can be done using simple commands, or by choosing the advanced option. Once all drives are added into a new drive group, you can set parameters and policies. You can unsubscribe at any time and well never share your details without your permission.
