LSI is adding some exciting new options to their Engenio 7900 storage system. The main new feature is support for STEC ZeusIOPS SSDs when using the FC4600 drive enclosure; according to the LSI these can provide 80 times the IOPS performance of traditional drives.
Another spectacular addition is the DE6900 SATA drive enclosure; it can hold a staggering 60 3.5 inch drives in a 4U enclosure. The current state-of-the art in disk arrays is 48 drives per 4U machine; the new density was achieved using front-loading drive drawers that remain functional while the drawers are open.
The improved 7900 unit can make this storage capacity available using a variety of protocols; the system can use dual-port 1 Gb/s iSCSI adapters, and 4 GB/s and 8 GB/s Fibre Channel interfaces. There’s no word on FCoE support or 10 Gb/s iSCSI, which is a bit disappointing; this presentation from last year specifically mentions that the unit is “10 GB/s iSCSI ready”.
Apart from that, the Engenio 7900 is a pretty solid unit, providing redundant just-about-everything. The data sheets mention it can achieve up to 170.000 sustained I/Os per second when using FC disks, and bursts of up to 700.000 IOPS when accessing its cache memory. The maximum raw capacity is 201 TB when using FC drives, or 480 TB when using 1 TB SATA drives.
The DE9600 uses Emulex’s SOC 422 Storage Switch and BR-2401 bridge to provice Fibre Channel to Setial ATA connections. It also integrates with the Tek-Tools Storage Profiler to gprovide in-depth monitoring and reports about storage performance. For more info about the improvements, there are several videos available on the LSI YouTube channel.
