EMC VNX – POOL PERFORMANCE PLANNING
In this post I will give a guideline on how to calculate the required drive count for a VNX Pool based on Throughput performance (IOPS). This is only a Rough-Order-of […]

In this post I will detail how to configure EMC FAST VP (Virtual Provisioning) on a VMAX storage array via SYMCLI, you can also use the “EMC Unisphere for VMAX” […]
Replacing a Disk in a VNX is quite a simple task if the correct procedure is followed (Discover the failed drive BED naviseccli -h SP_IP faults -list). In this post […]
In this post, I’ll detail some useful commands that can be leveraged to rename Cisco zoning components: FCALIAS ZONE ZONESET RENAME ALIAS FOR HOSTS (vsan id of 10): switch(config)# fcalias rename old-AliasName new-AliasName vsan 10 RENAME ZONES: switch(config)# zone rename old-ZoneName new-ZoneName vsan 10 RENAME ZONESETS: switch(config)# zoneset rename old-ZoneSetName new-ZoneSetName vsan 10 Once complete Activate and Commit these changes: […]
This is one that caught us by surprise! As per previous blog Post “EMC RecoverPoint Architecture and Basic Concepts” this is the port configuration as per the initial release of […]
Today I had a VNX Data Mover (Blade) slic issue where the failover relationships were not as they should be. The following commands are very useful for checking the relationships […]
When building a Vblock720 I use the following information to assist in Zoning and Masking of UCS Blades. In order to gather the wwn’s of all the VMAX front-end director […]
In this post I will detail some considerations for RecoverPoint Journal and Replica Volumes from a Performance Perspective. This will give you some insight into the workings and designs that […]
This post is a result of having to migrate Cisco UCS Blade boot LUNs between Raid Groups. Both the source and destination were Classic LUNs – RAID Group LUN (FLARE […]
A very important consideration is the capacity sizing of your RecoverPoint journals which is done on a per Consistency Group basis. This will dicatate the level of failback allowed (Protection Window) on a per CG configuration. The JV must have the correct performance characteristics in order to handle the total write performance of the LUN(s) being protected (next blog). They […]
This is my first blog on RecoverPoint; in this initial post I will detail some of the basic concepts and terminology around RecoverPoint and the GEN 5 hardware appliance specification. […]
This is the second part in the series on configuring the VNXe via command line. Here I will detail the Steps involved in creating both NFS and iSCSI datastores. The configuration steps outlined in Part2 will be the following: LACP Configuration Create the Network Interface for NFS NFS Shared Folder Server Configuration Create NFS datastores Creating iSCSI Interfaces/Nodes/Datastores LACP Configuration Link […]
This is the first in a series of blog posts on configuring VNXe using the command line. All the configurations here will be performed using “uemcli” which can be downloaded here . If you prefer to use the GUI interface then Henri has a very good series of blog posts here. The following scripts defined here are very useful if […]
This script is a result of having to create quite a large number of dedicated Masking views for VMware ESX 5.x server boot volumes and Masking Views for shared vmfs datastore clusters. In this example I will create two dedicated ESX server MV’s and one Cluster Masking View consisting of the two ESX Hosts sharing a VMFS datastore. Each VMware […]
Here I will detail the steps involved in upgrading the OE for file and block on the VNX. Using the Unisphere Service Manager is the recommended method of upgrade. The […]
EMC ‘FAST Cache’ technology gives a performance enhancement to the VNX Storage Array by adding FLASH drives as a Secondary Cache, working hand-in-hand with DRAM Cache and enhancing overall Storage […]
