RAID Cache

When used as a write cache in enterprise-class storage applications, AGIGARAM® provides a performance-boosting building block while guarding against power failures and consequent loss of critical data. IT managers know that integrating a RAID controller cache increases system performance by reducing latency of I/O requests. Even milliseconds of latency can cost companies millions of dollars in lost revenue. One of the drawbacks of RAID caching however, is that the data is stored in volatile memory and can be lost when a system power outage occurs. For years, the answer to this was to implement a battery backup unit (BBU) which holds the data in the event of a power loss for up to 72 hours. However, BBUs have significant drawbacks that have made them a necessary evil in the storage space. With AGIGARAM technology, this all goes away.

With AGIGARAM as a flash-backed write cache, there is no downtime due to learning, conditioning and maintenance cycles as there is with battery-backed solutions. And downtime costs money. In addition, during a power loss, AGIGARAM vaults the contents of DRAM to NAND Flash, preserving the data for up to 10 years. For battery-backed solutions, this data is only held for 48 to 72 hours.
