Intel 320 Series SSD User's Information for Dell PowerEdge C Products 1 About This Document This document describes features and behaviors of the Intel 320 Series SSDs that you may encounter when using these drives in a Dell PowerEdge C server. Supported Hardware PowerEdge C Servers The following Dell PowerEdge C servers are currently qualified as compatible with Intel 320 Series SDDs: • PowerEdge C6220 NOTE: Additional servers may be qualified in the future as compatible with Intel 320 Series SDDs.
SSD Hard Drive Indicator Patterns Figure 1. Hard-Drive Indicators 1. hard-drive activity indicator (green) 2. hard-drive status indicator (green and amber) Drive Activity Indicator NOTE: The drive activity indicator behavior on an SSD is noticeably different than that of a hard disk drive. When SSD I/O activity is occurring, the indicator will switch on and remain on without blinking. This is normal behavior.
SSD Drive Status Indicator Pattern (RAID Only) Condition Steady green Drive online Blinks green three seconds and off six seconds Rebuild aborted Wear Usage Monitoring The Smartmon Tool You can use a software tool — Smartmon — that monitors three Self-Monitoring, Analysis, and Reporting Technology (SMART) attributes for SSDs. Smartmon includes a command line utility, smartctl, used to check these attributes.
Monitoring Drive Wear Example Using the Smartmon Tool — Linux RAID Environments Note that the specific options in this example may not apply to your system. For details of the smartctl commands and options, see the resources in “Smartmon Tool and smartctl Resources.” 1. Find the OS name for the storage device or RAID array. 2. Find device ID’s for the device or array in step 1 using MegaCli using the following command: MegaCli64 –pdlist –aAll 3.
– For example, utilizing smartctl version 5.43 in a Linux OS where the drive under test is /dev/sda you can enter the following command line: smartctl –t vendor,0x40 /dev/sda. Figure 2. Resetting the SMART workload timer attribute 4. Return the drive to the Windows system where the workload will be measured. 5. Run the workload to be evaluated for at least 60 minutes (otherwise the drive wear attributes will not be available). – For this example, the workload was run for about 22 hours.
Figure 3. Reading the SMART drive wear attributes The table below translates the data from smartctl to the Intel-supported SMART Attributes. Table 1.
– Workload Media Wear Rate 0.027% per hour – Workload Media Wear Rate 0.653% per day Using the drive in this 100% workload example, the drive wears at .653% per day. • 100/.653 = 153 • In this exaggerated case, the drive will use 100% of wear in 153 days NOTE: This sample usage case is an exaggerated workload of 100% writes. The wear rate and related values for this device's intended use in read-intensive environments will be notably different, with the wear rates markedly lower.
