Storage System Configuration and Management

Upon completion of this module, you should be able to:• Configure SP Networking• Validate SP Write Cache Configuration

Storage System Configuration and Management 1



During this lesson the following topics are covered:• Configure VNX management ports• Configure VNX FC ports• Configure VNX iSCSI ports• Configure VNX FCoE ports

Lesson 1: Configuring SP Networking



Locating System Hardware



Configuring SP Management Ports: Storage Hardware


Right-click on the SP and Virtual port to launch the SP Network Properties


Configuring SP Management Ports from Settings



Locating iSCSi Ports


Right-click to launch iSCSI Port Properties


Configuring iSCSI Ports


Supply the IP address, Gateway and Subnet Mask in the IPv4 Configuration field


Locating FCoE Port Properties



Configuring FCoE Ports



iSCSI Front-end Port Properties



FCoE Front-end Port Properties




During this lesson the following topics were covered:• Configuration of SP management interfaces• Setup of FC, iSCSI, and FCoE ports for block data access

Lesson 1: Summary




During this lesson the following topics are covered:• Describe the benefits of VNX MultiCore Cache• Verify that Write Cache is enabled

Lesson 2: Enabling SP Cache



VNX Multicore Adaptive Cache• Data written to cache• Data is copied to disk• Data kept in memory



Benefits of VNX Multicore CacheMCC Aspect BenefitDynamic Watermarks Monitors the I/O demand

• Measuring the rate of incoming I/Os

• Monitoring underlying RAID groups

Flushing and Write Throttling • Auto adjust incoming and outgoing I/Os per RAID group

• Provides the time needed to adjust pre-cleaning age

• Prevents 100% utilization of Cache by write-intensive workloads.

• Protect the array from the monopolization of resources by a single workload



Multicore Cache: Write Cache Option• Write Cache enabled (default)

Writes are acknowledged once accepted into cache (and mirrored)

• Write Cache disabled Writes directly to disk Writes are only acknowledged when

written to disk• Unchecking Write Cache will have

significantly negative impact on performance


EMC recommends Write Cache always be enabled



During this lesson the following topics were covered:• Multicore Cached provides benefits of Adaptive Cache,

Dynamic Watermarks, Flushing and Write Throttling• VNX Write Cache in enabled, by default, and provides

dynamic operations to benefit performance

Lesson 2: Summary



SummaryKey points covered in this module:• Unisphere wizards for Network settings can be used to configure

SP management ports• Block data ports for iSCSI, FC, and FCoE can be managed by

navigating through Unisphere to Settings > Network > Settings for Block• VNX Multicore Cache in enabled by default and dynamically

adjusts to provide optimal performance
