Abstract
This document describes characteristics of the volatile and non-volatile
memory components of the Dell EMC E660/E660F/E660N. The information contained
within this document is pertinent to system owners that may need to qualify
the risk associated with ensuring that all memory within a product has been
cleared in compliance with regulatory requirements.

Executive Summary
To facilitate the most effective and efficient functionality, most information technology systems utilize various forms of data storage. These may include Random Access Memory (RAM), ReadOnly Memory (ROM), flash memory, virtual memory, and magnetic storage devices. Each form of storage maintains unique characteristics that may affect how organizations protect information stored by the system. In particular, storage devices may retain data for a period of time after power ceases to be provided. In order to adequately protect information and make appropriate decisions that support regulatory requirements, it is critical to understand all of the storage components and their memory volatility characteristics. This paper will provide the necessary information for organizations on which to base their decisions about the response to security incidents and regulatory compliance.
Introduction
Memory components are categorized as either volatile or non-volatile. Volatile
memory includes Random Access Memory (RAM) such as Static RAM (SRAM) and
Dynamic RAM (DRAM). Non-volatile memory includes Read-Only Memory (ROM),
Electrically Erasable Programmable ROM (EEPROM), Non-Volatile RAM (NVRAM), and
Flash memory devices. Because of their unique characteristics, systems may use
a combination of memory types to maintain efficient and effective
functionality. In order for organizations to determine mitigation steps
following a security incident or to make decisions about steps that should be
taken before changing the approved system confidentiality, a solid
understanding of the memory volatility specific to the product needs to be
established and well-documented.
Purpose
The purpose of this document is to provide organizations with knowledge about
memory volatility within the DellEMC E660/E660F/E660N on which security
decisions can be made and, where appropriate, remediation steps that can be
incorporated into organizational processes.
Scope
This document provides a description of short-term memory storage components
and their characteristics including, where appropriate, the method by which
memory can be cleared. It is intended to provide product-specific memory
volatility and may supplement organization-specific policy, standards, or
guidance.
