I swapped the P300 and P400e drives when running performance tests. The P300's read performance is a little better at 60,000 IOPs random and 360 Mbytes/s sequential but its sustained random write IOPs exceeds 16,000. The P400e's read performance is 50,000 IOPs random and 350 Mbytes/s sequential. The P300 is an SLC enterprise drive while the P400e is an MLC enterprise drive. These includeded RealSSD P300 (see Building A Hybrid RAID NAS Server) and the Micron RealSSD P400e SSD drives. (see Family Of Drives Span Enterprise Storage Needs) The 2.5-in drives used with the tests included five The MegaRAID SAS 9260-8i fits in any of these slots. SuperMicro's 4U AS-4022G-6F A+ Server has three x16 and three x8 PCI Express slots. The original testing for that project was done using the built-in LSI SAS controller but for this test I disconnected the on-board controller and used only the SAS 9260-8i.įigure 2. (see Hands-on SuperMicro's 32-core A+ Server).

2) that had two, 16-core Opteron 6000 Series processors I popped it into SuperMicro's 4U AS-4022G-6F A+ Server (Fig. The LSI MegaRAID SAS 9260-8i handles 8 SAS or SATA II drives. In general, CacheCade provided near SSD performance overall when mixed with a hard drive array and FastPath enabled SSDs were almost twice as fast as the same array without FastPath enabled.įigure 1. Getting the same results of any tests I would do would require identical hardware. Large hard drive arrays with SSD caching would employ CacheCade.īecause of this variance in architectures I am going to be addressing installation, configuration and features rather than performance. MLC (multi-level cell) SSDs and FastPath is probably the best choice.

These are extra options so it is possible to install what your system requires.įor example, if RAID 1 is sufficient but you want SSD caching support then CacheCade is all that is required.įastPath is designed to optimize SSD arrays.Īs usual, your mileage may vary and most installations will concentrate on one type of configuration based on the application mix.įor example, a high performance transaction system might employ SLC (single-level cell) SSDs that have higher write endurance than

The controller was delivered with LSI's CacheCade Pro 2.0 and FastPath software on-board along support for RAID 5 and 6.
EUFI support is standard but battery backup support is optional. The controller contains 512 Mbytes of DDR2 RAM. The eight channel, 6 Gbit/s RAID controller is based on the LSIAS2108 RAID-on-Chip technology. (see SAS RAID Controller Handles Hierarchical Storage) but I have finally got my hands on one (Fig. It has been awhile since LSI's MegaRAID SAS 9260-8i was available
