NetApp 111-01158+B0 NVRAM8 2 x Ports 4G QSFP with Battery CACHE Adapter for FAS6290 FAS6220

Product Description

The NetApp NVRAM8, identified by part number 111-01158+B0, is a high-performance cache adapter engineered to bolster the capabilities of NetApp FAS6290 and FAS6220 storage systems. Its core function is to provide non-volatile cache memory, meaning that data written to the cache is immediately considered safe and can be acknowledged to the host system without waiting for physical disk writes. This significantly accelerates write operations and improves the overall responsiveness of the storage array. A key feature of the NVRAM8 adapter is its integrated battery backup unit. In the event of an unexpected power outage or interruption, this battery provides sufficient power to safely write any data residing in the volatile cache memory to persistent storage before the system shuts down. This crucial data protection mechanism prevents data loss and ensures the integrity of stored information, a vital requirement for enterprise-class storage solutions. Connectivity is provided via two 4G QSFP (Quad Small Form-factor Pluggable) ports, which are designed for high-bandwidth, high-density applications. These ports enable rapid data exchange between the cache adapter and the storage system's controllers and drives, ensuring that the adapter can keep up with the demanding I/O workloads typical of the FAS6290 and FAS6220 platforms. The NVRAM8 adapter is thus an essential component for optimizing performance and ensuring data reliability in critical storage environments.
