EMC Storage Product Knowledge Sharing

Lets understand EMC Open Replicator product:- Open Replicator enables remote point-in-time copies with full or incremental copy capabilities to be used for high-speed data mobility, remote vaulting, migration, and distribution between EMC Symmetrix DMX and other qualified storage arrays. OR leverages the high-end Symmetrix storage architecture and offers unmatched deployment flexibility and massive scalability. EMC Open Replicator is tightly integrated with EMC TimeFinder and SRDF families of local and remote solutions. Open...

PowerPath Migrator Enabler is a host-base migration tools from EMC that allows you to migrate data between storage systems with little or no interruption to data access. This tool can be use in conjunction with other underlying technology such as EMC Invista, Open Replicator. PPME use the PowerPath filter dirvers to provide non-disruptive or minimally disruptive migrations. Only specific host plateforms are supported by PPME. Please check EMC support matrix for supported host systems. One of the PPME features that supports...

In the current storage markets and technology, storage tiers are defined by availability, functionality, performance and costs. In fact data can move up and down tiers as time and business required.Tier "0" is not new in storage market but for implementation purposes it has been difficult to accommodate because it requires best performance and lowest latency. Enterprise Flash disks (Solid State Disks) capable to meet this requirement. It is possible to get more performance for company most critical applications. The performance...

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...

SRDF/S and SRDF/A configuration involves tasks such as suspending and resuming the replication, failover from R1 side to R2, restoring R1 or R2 volumes from their BCV, and more. You perform these and other SRDF/S or SRDF/A operations using both symrdf and TimeFinder command symmir. The below details are for SRDF Pair states during SRDF procedure.SyncInProg :- A synchronization is currently in progress between the R1 and the R2. There are existing invalid tracks between the two pairs and the logical link between both sides of...

Symmetrix Optimizer improves array performance by continuously monitoring access patterns and migrating devices to achieve balance across the disks in the array. This is process is carried out automatically based on user-defined parameters and is completely transparent to end users, hosts and applications in the environment. Migration is performed with constant data availability and consistent protection.Optimizer performs self-tuning of Symmetrix data configurations from the Symmetrix service processor by:· Analyzing...
