X1937A-R5 NetApp Performance Acceleration 2 (PAM 2) 256GB PCIe Module – 111-00660, 110-00153

The cost of delivering IT services is under more pressure than ever. Hard constraints on budget and staff collide with expectations for more and better, and networked storage systems are a case in point. Providing enough capacity is easy. Keeping pace with performance demands can be difficult because, while they are getting bigger, disk drives aren’t getting any faster. Installing Performance Acceleration 2 (PAM 2) modules with part numbers X1937A-R5, 111-00660, and 110-00153 will give you a new way to optimize the performance of your storage system without adding disk drives.

Use our Performance Acceleration Modules (PAMs) to optimize the performance of random read intensive workloads such as file services, messaging, virtual infrastructure, and OLTP databases without adding more high-performance disk drives. These intelligent read caches speed access to your data, reducing latency by a factor of 10 or more compared to disk drives. Faster response times can translate into higher throughput for random I/O workloads.

PAM family modules give you performance that is comparable to that of solid state disks (SSDs) without the complexity of another storage tier. You don’t need to move data from tier to tier for the best performance. It’s all automatic because every volume and LUN behind the storage controller is subject to caching.

You can also reduce costs for storage, power, and rack space with our PAM family modules. We have demonstrated that the original PAM caching module can eliminate up to 50% of the disk drives in a storage system with no change to I/O throughput. Similar tests with a new PAM 2 module reduced the number of disk drives by about 75%.
