Quad Slot Expander Model LTNG-XQ
The Lightning XQ Quad (4) Slot Thunderbolt Expander models are available with red accents, or all black as shown; they are available with or without the 8-drive ready RAID subsystem and internally installed RAID controller as well! Please specify your color preference as well as whether you desire the 8-disk RAID-ready storage subsystem as described. Note there are four model numbers detailing the RAID option and the product color scheme.
The new JMR Lightning LTNG-XQ-8-RM is a four-slot Thunderbolt-2 to PCIe expander with an internal hardware (6Gb SAS) RAID controller and an 8-bay disk RAID array for working storage. This is an Intel-Certified product featuring four x16 (mechanically, x4 electrically) PCIe expansion slots and quad 20Gbps Thunderbolt-2 I/O ports so other compatible Thunderbolt products may be daisy-chained beyond the Lightning product.
Included in this 4U rack mount product is a Thunderbolt-compatible ATTO SAS RAID controller installed in one of the PCIe slots, and an integrated, hot-swappable RAID disk storage subsystem which may be populated with any compatible 2.5” SFF drives, either rotating or SSDs – thus providing “on board” storage up to 32TB!
It has internal forced air cooling and is powered by an internal 460 Watt power supply, and is attractively packaged with a rugged powder coated finish. The LTNG-XQ works with all Thunderbolt-2 compatible PCIe peripheral devices; common applications include:
- SAS/SATA host bus adapters and RAID controller cards
- Video capture cards
- Fibre channel host bus adapters and RAID controller cards
- Audio interface cards
- 10GbE network adapter cards
- Graphical Processing Units (GPUs), RED Rocket-X cards
The LTNG-XQ-8-RM supports all compatible PCIe cards, up to full-height and full-length peripherals. It provides additional DC power connections for GPUs requiring those connections.
Unique design: The LTNG-XQ is the only product on the market featuring four full-bandwidth PCIe slots, using two independent Thunderbolt™ 20Gbps bridge circuits: One Thunderbolt bridge drives two slots, and a second internal Thunderbolt bridge drives the other two slots. Connections to the host MacPRO include using two of the three available Thunderbolt bus connections to the Mac. Daisy-chain expansion beyond the LTNG-XQ is also available via its four Thunderbolt expansion ports.
The advantage of this architecture is enhanced operating bandwidth for demanding applications which will utilize all the 20Gbps bandwidth available from each Thunderbolt port. Models of the LTNG-XQ include internal hardware (SAS) RAID controllers and eight RAID drives (rotating or SSD), and the storage array can operate at “full speed” (1200+ MB/s transfer rates) using one bus while other demanding peripherals can operate at full speed using the other bus!
The unique packaging design provides “Lightning in a Drawer” functionality: The LTNG-XQ-8-RM is a “sled” device that docks into a provided bracket that installs into a conventional rack equipment cabinet (using only the front vertical rail) and then slides into the docking bracket for quick, easy installation or servicing. The unit also docks with our popular Mac ProBracket model MPRO-DUAL-RM which provides a 16” deep “shelf” to accommodate the Lightning XQ as well as a MacPRO computer all in 4U of rack space.
Using popular SFF SSDs in the RAID easily provides sustained data transfer speeds >1200 MB/s for “working” files.
