The RamSan-6300
is a full rack of RamSan-630 systems. These multiple systems can be used
together to support applications that need more performance or capacity than a
single RamSan-630 can provide.
The RamSan-6300 has these key features:
- Sustained I/O rates of 14,000,000 IOPS
- Sustained, random bandwidth of 140 GB/sec
- 70 dual ported 8-Gbit Fibre Channel controllers
- 70 dual ported QDR InfiniBand controllers
- Enterprise grade SLC Flash with on-board RAID
protection
- Advanced chip-level ECC circuitry to provide bit
correction when needed
- Wear-leveling technology to extend the life of the
system
- Non-volatile solution

Performance
The key measure of the RamSan-6300's capabilities is its
ability to sustain extreme IOPS even with mixed read/write workloads. Most
other hard disk drive (HDD) solutions suffer significant performance degradation
from either random access patterns or write accesses. A RamSan-6300 will
deliver better sustained "real world" application performance than any other
Flash SSD.
Connectivity
The RamSan-6300 can connect directly to servers or
through Storage Area Networks (SAN) using Fibre Channel or InfiniBand
interfaces. By leveraging direct attached and SAN architectures, the
RamSan-6300 offers some important advantages, such as:
- Shareability
- Redundancy
- Ability to provision the exact SSD capacity that an
application requires
- Centralized management.
Reliability
In order to meet enterprise reliability requirements,
the RamSan-6300 includes three layers of Flash memory protection. The first
layer is an ECC circuit that detects and corrects single bit errors. The second
layer is the use of a modified RAID-5 algorithm to ensure that the failure of a
Flash memory chip does not result in data corruption. The third layer, Active
Spare, protects against a card failure.
