The controller improves the storage performance while retaining the current investment in direct-attached storage (DAS). These cards are built upon the enterprise hardened RAID technology and industry leading Flash storage controller solutions. The controller reduces write latency by efficiently using DRAM. The controller provides DRAM cache offload support and DRAM Write Back support. The controller helps you create a Nytro DM VD with Write Back, cached, and no read ahead properties. The supported RAID levels are: RAID 0, RAID 1, RAID 5, and RAID 10 with Write Back and Write Through modes. The controller supports LSI SFMs that you can plug in and install, and flash firmware.</a></p> <p class="Body"><a name="3_4_3_5">The controller is easy to use with transparent access to applications. This industry proven LSI solution enables many applications enjoy the performance improvement seamlessly from the controller without any application or file system modifications.</a></p> <p class="Body"><a name="3_4_3_6">The Nytro DM controller is based on LSISAS2208 RAID On-a-Chip (ROC).
