LSI MegaRAID 9260-8i 6G Review – 2.5GB/s Speed Through 8 SSDs

LSI 9260-81

Hot on the table in our labs today is the LSI 9260-8I MegaRAID 6Gb/s SATA+SAS internal RAID card and it happens to be sitting beside 8 Crucial C300 SATA 3 SSDs and 8 OWC Mercury Extreme Pro RE SSDs.

We are going to put this card through its paces and brace yourself because we have been pulling off amazing speeds as high as 2.5GB/s and 1.7GB/s for high sequential read and write access.

.

As amazing as this review is, in that we don’t really get the chance to test any piece of technology with 8 SSDs of each SATA interface every day, we have to let you know right off its just a teaser. Our follow up review will be an exclusive review of the newly released to be released LSI MegaRAID 9265-8i MegaRAID Card which is capable of 2.7GB/s read and 3.3GB/s write access with an amazing 465, 000 IOPS.

INTRODUCTION

The LSI 9260-8i MegaRAID card is a SATA 3 internal RAID card that allows us to connect up to 8 hard drives (or in our case SSDs) in a variety of multi-level RAID configurations to include RAID 0, 1, 5, 6, 10, 50 and 60. It installs through a quick clip into your motherboard PCIe 2.0 x8 slot and, as we saw with this card, is recognized immediately.

This value of this card becomes more apparent as we move into the world of solid state drives and higher storage speeds, the same speeds that become bottle-necked at around the 600MB/s mark through use of Intel ICH10 RAID configurations. The ability of this card to bring us into speeds in excess of the 2GB/s mark, not only lets us push bar when it comes to our system performance, but also opens the door to any number of possibilities in the enterprise world.

Take a quick peak at this video which demonstrates the use of the 9260-81 in ‘The Dark Energy Survey’ which tries to tackle one of todays greatest scientific mysteries, why the acceleration of the univers seems to be speeding up.

PHYSICAL COMPOSITION

At the heart of the LSI 9260, is the 800MHz PowerPC LSISAS2108 ROC which is located beneath the silver heat sink and is the sole reason they can advertise amazing speeds of 2.8GB/s read and 1.8GB/s write access speeds for the unit. To the left of this are two SFF 8087 mini- SAS connectors which, as we will see, allow for the connection of 8 SSDs through LSIs SAS to SATA connectors. On the right, there are 5 modules of Micron flash which provide for the 512mb of on board cache and there is a connector for the battery backup unit which can provide the card with enough power to preserve data for 72 hours. Last but not least, there is a sound alarm which is located lower left of the RAM.

There is not really much of interesting the rear except for the PCIe 2.0 x8 which also works in 4 or 16 powered slots.

  • SafeStore Encryption Services for more secure data protection
  • Low-profile MD2 form factor for space-limited 1U and 2U environments

LSI MegaRAID SAS/SATA 9265-8i 6Gb/s PCIe RAID Card Review – Performance Unleashed

Featured

Following our last reviews of the Areca 1880 RAID Card and LSI 9260-8i MegaRAID Card, we are going to take an indepth look at LSIs new release, the LSI 9265-8i MegaRAID Card, an eight-port PCI Express SATA+SAS RAID Controller that is configured for 6Gb/s devices.

.

.

With the speed and power of SSDs reinventing mainstream storage, RAID card manufacturers are challenged to deliver a product that can handle the massive throughput and high random reads of these solid state drives. Manufacturers then raise the bar by combining these SSDs into ultra speedy RAID arrays, the end result of which is shown in the LSI 9265-8i as we have today.

THE LSI CHALLENGE TO IMPROVE

The SSD has literally been a ‘game changer’ for the world of storage and LSI first began to address this issue with the highly successful 9260 series of cards, these having sold 400,000 cards worldwide. At the heart of the MegaRAID series is the LSI 2108 ROC controller (and other iterations), which have proven to be the key to LSI’ success.

These ROC controllers are now used by several vendors, which include IBM and Intel. Currently no company is able to provide the computational power to handle such heavy loads outside of LSI, LSI being a company presently enjoying a 3x performance lead over their nearest rivals in this realm. It seems that the only company that seems to be able to challenge LSI, is LSI itself, and they have returned with the 9265-8i, a card which raises the bar on storage performance to even higher levels!

INTRODUCTION

  • Ability to achieve 465,000 IOPS with a single controller
  • 4x IOPS performance advantage over the closest competitor
  • 3x greater IOPS than LSI’s 1st generation 6Gb/s controllers
  • 10x greater IOPS than today’s 3Gb/s controllers
  • 67% improvement in RAID 5 & 6 sequential writes (up to 2600 MB/s)

These are just a few of the selling points of the 9265 MegaRAID card, whose controller boasts a new ROC, the LSISAS2208 Dual- core 6Gb/s ROC- x2 800MHz PowerPC Processor. This ‘engine’ is key to its performance, it leverages the increased throughput of the x8 PCI Express 2.0 host interface for higher throughput and ease of connection. Even this bus is proving to be ‘squeezed’ here by the sheer power of this card.

Another big step forward is the expansion into DDR3 cache running at 1333MHz, this being the first available controller to use this speed of cache, with previous generations using DDR2 800 MHz. This will enable faster write performance on the controller in certain scenarios. The raid card provides a plethora of connectivity for all of your storage needs, fully supporting all speeds of SAS and SATA, all the way up to 6Gb/s!
