Chapter 1 – Introduction

1.1Overview

The RamSan-325 series solid-state disk uses DDR RAM (memory) as its primary storage. This technology enables practically instantaneous data access, which results in dramatic application performance increases.

Texas Memory Systems (TMS) designed the RamSan to be highly available and fault tolerant. The system has higher availability than RAID or JBOD systems because the primary storage media is DDR RAM, which does not require moving parts. Additionally, DDR RAM has a very high mean time between failures (as high as several hundred years) according to some studies. The mechanical components in the RamSan are redundant and hot swappable.

The RamSan-325’s internal disk drives provide a fully non-volatile solution. The RamSan-325 has two modes of operation: Active BackupTM mode and DataSync mode. For more information on these modes, see Section 6.9 - Setting Backup Mode.

The RamSan complements existing disk drives, JBOD, or RAID, in performance sensitive applications. Servers perceive the RamSan as another attached SCSI disk drive. For some applications, the RamSan is the only storage system required. For applications that store terabytes of data, storage administrators add the RamSan to systems that include RAID or JBOD.

Connect the RamSan via Fibre Channel to host servers, NAS filers, or storage network switches and hubs. If you have specific compatibility questions, please contact Texas Memory Systems.

Use the RamSan in a variety of applications. If hard disk drives slow down your application, there is a good chance that the RamSan can speed it up.
