Version 9.6
- K2 Storage platform - There is now support for third generation higher
density (M110) hard drives for online and production systems. In addition to
greater storage capacity, there is a 25-50% increase in system bandwith. New
drives for production and nearline storage systems supporting twice the storage
capacity include: 1.8 TB 10K RPM SAS drives (for online storage), 4TB 7.2K RPM
SAS drives and 6TB 7.2K RPM SAS drives (for production and nearline storage).
The biggest performance gain for the new drives is in write bandwidth and
throughput. The gain increases with LUN count: in a 50% read/write usage model,
there is a 10-25 percent increase in bandwidth for a given LUN count. Also
included is a new RAID controller with 16Gb-capable Fibre-Channel interface.
(When fully supported, this doubles the interface speed of current controllers.)
The new M110-based storage platform introduces significant performance gains in write bandwidth and throughput. The storage platform supports RAID 5 and RAID 6. RAID 5/RAID 6 uses disk striping with parity. Disk striping spreads the data across multiple drives. Because the data and parity are striped across all of the disks, no single disk is a bottleneck. Also, there is the ability to reconstruct data in case of a disk failure. Upon failure of a single drive, the system is still operational. Hot-swapping of drives is supported: in the event of a hard drive failure, you may replace the drive without having to shut down the server. You may choose from a variety of configurations for a maximum of 12 3 1/2 inch drives or up to 24 2 1/2 inch drives per chassis.

SMPTE 2022-6 Redundancy - The IP Redundancy feature uses two K2 Summit channels in Player/Recorder mode to provide seamless protection switching between redundant pairs of SMPTE 2022-6 media streams. Using the IP Redundancy feature requires using specific pairs of K2 Summit channels. Channels C1 and C2 can be used to form one redundant pair. Channels C3 and C4 can be used to form another redundant pair. Both channels in the redundant pair must be configured for Player/Recorder mode in order to be able to enable the IP Redundancy feature. Each channel in the redundant pair can be independently used to Play or Record clips with IP Redundancy.
