Promise Pegasus Raid

After announcing their intention back in February 2011 of releasing Thunderbolt enabled products, Promise have now launched a number of Thunderbolt hard drive devices.

The Promise Pegasus Raid R4 and R6 boast I/O rates of over 800 MB/s. They are the first High Performance Hardware RAID solutions available with Thunderbolt ports. Each has two high performance bi-directional Thunderbolt ports capable of transferring data at 10Gbps.

Promise Pegasus R4 and R6 Raid enclosures have either 4 drive bays or 6 drive bays available.

Both enclosures support RAID 0, 1, 5, 6 and 10, utilising either 1TB or 2TB disks. They all come preconfigured with RAID 5.

There are four models available across the range with varying disk capacities.

Promise Pegasus R4: 4TB                    Promise Pegasus R4: 8TB

4 x 1TB disks                                        4 x 2TB disks

2.7TB capacity (formatted with HFS+)    5.7TB capacity (formatted with HFS+)

Promise Pegasus R6: 6TB                    Promise Pegasus R6: 12TB

6 x 1TB disks                                        6 x 2TB disks

4.7TB capacity (formatted with HFS+)    9.7TB capacity (formatted with HFS+)

Each array uses 3.5” 7200 RPM SATA hard drives.

Promise Pegasus Raid

The Promise Pegasus is ready to use as soon as you take it out the box. Just plug in the power, connect the Thunderbolt cable and away you go.

The Thunderbolt cable is not supplied with the Pegasus unfortunately.

They are available from Amazon

 

In addition, it is worth mentioning that the Promise Pegasus will only work on the 2011 MacBook Pro or 2011 iMac. This is because they are the only two products currently available that have an integrated Thunderbolt controller. A controller is required in order to encode and decode the transferred data.

The MacBook Pro or iMac also require the Mac Thunderbolt firmware update available at the Apple website http://support.apple.com/kb/DL1407

The power button glows orange during startup and then turns blue when everything is up and running ok. If there is a problem with the array, the power button will be red.

There is a new OS X GUI management utility from Promise that requires Mac OS X v10.6.8 or later (Lion is supported).

The bundled Promise Utility has been specifically designed for use with a MAC. It gives you full control over the Pegasus.

You can configure the array to suite whatever your requirements are and produce array or drive health reports if required.

Promise SANlink adapter

Promise SANLink

 

 

 

 

 

Promise SANlink adapters allow any computer with a Thunderbolt interface to connect to a SAN. It acts as a bridge allowing two high speed technologies to coexist together.

A SANlink adapter provides dual 4Gbps Fibre Channel ports that automatically detect connection speed, and can operate independently at 1, 2 or 4Gbps.

The Promise SANlink adapter has two Thunderbolt ports. The low latency, dual-channel nature of Thunderbolt allows you to daisy chain additional peripherals without compromising the performance of the Fibre Channel connection.

Now with a SANlink adapter you can connect an iMac to a xSAN network allowing you to quickly access shared resources stored on the xSAN.
