EMC Storage Product Knowledge Sharing

BCV copies can be used for backup, restore, decision support, and application testing., BCV devices contain no data after initial Symmetrix configuration. The full establish operation must be used the first time the standard devices are paired with their BCV devices. 1.  Associate the BCV Device for pairing:To perform standard/BCV pairing, the standard and BCV mirror devices of your production images must be members of the same device group (Note:- Already discussed in previous post about creating device group and pairing...

Think when you are creating a point-in-time image for multiple devices. It is easy to create a point-in-time image of entire set of logical device at same time. In order achieve this you need to shut down an application so that no IO will occurs while you creating a point-in-time image. This is big problem in today’s environment where every company looking solution for zero down time.The EMC provided solution to this problem is called “Enginuity Consistency Assist”. When you create a set of sessions and invoke Enginuity Consistency...

Auto-provisioning requires Enginuity 5874 or later. It simplify Symmetrix provisioning by allowing you to create group of devices like storage group in CLARiiON, Front-End Port Group and Host Initiators Group and then associate these groups with each other in a masking view.The following are the basic steps for provisioning Symmetrix using Auto-Provisioning:-1) Create a Storage Group2) Create a Port Group3) Create an Initiator Group4) Associate the groups in a Masking View.Creating Storage Group:- It is component of Auto-Provisioning...

We have discussed about Virtual Provisioning of Symmetrix in previous post. Now, we will discuss about Virtual Provisioning Configuration. You have to understand your storage environment before you run the below mentioned command.Configuring and viewing data devices and pools:Data Devices are devices with datadev attribute. Only Data Devices can be part of Thin Pool. Devices with different protection scheme can be supported for use in Thin Pools. It is depending on specific Enginuity level. All devices with the datadev attribute...

EMC announced Symmetrix V-Max recently which is based on virtual matrix. Symmetrix V-Max runs on latest Enginuity 5874.
