This post is just an attempt to shed some light as to what a BIN file is, how it works, what’s in it and why is it essential with the Enginuity code. . Some EMC folks have capitalized on the BIN file as to the personality it brings to the Symmetrix, while the EMC competition always uses it against them as it introduces complexities in the storage environment with management and change

       The Zoning Migration within SAN Fabric can import complete zone set information and aliases without any effect on existing SAN fabrics, simplifying SAN migration between different vendors. Such as Cisco, Brocade and McData.          Import of zone set(h/w + s/w) actually save up a lot time for the migration work

In this blog post we will discuss the supported drive models for EMC Symmetrix DMX-4. Right before the release of Symmetrix V-Max systems, in early Feb 2009 we saw some added support for EFD’s (Enterprise Flash Disk) on the Symmetrix DMX-4 platform. The additions were denser 200GB and 400GB EFD’s. The following size drives types are supported with Symmetrix DMX-4 Systems at the current

In order to use the control functions of Solutions Enabler, you must create device groups and add/associate Symmetrix devices with the group. The following example shows how to create a device group, add a standard device to it and associate two BCV devices to the group. The following commands will create a device group using the default type (regular). Next we will add a device to the

The below is the true breakdown of the type of the EMC Symmetrix and EMC DMX machines to the type of cabinet properties it has.  Starting with the Symm 3.0′s EMC introduced a 1/2 Hieght cabinets, Single Full Cabinet and a 3 Cabinet machine. The same ideas went into the Symm 4.0 and 4.8.  Starting the Symm 5.0 and into Symm 5.5, EMC introduced the Badger cabinets, which

                      EMC Symmetrix V-Max systems were introduced back in the month of April 2009. With this new generation of Symmetrix came a new name V-Max and a new Enginuity family of microcode 5874.           With this family of microcode 5874:

        When configuring zoning or other fabric-wide settings in a fabric that has products operating with different versions of FOS, it is recommended that the configuration be performed via an interface (such as WebTools) to a product with the most recent version of FOS.         Some older versions of FOS do not fully support newer

Contact your switch supplier for hardware, firmware, and software support, including product repairs and part ordering. To expedite your call, have the following information immediately available : 1.

Here is the quick and dirty math on EMC Symmetrix Heads, Tracks, Cylinder sizes to actual usable GB’s of space. Based on different generations of Symmetrix systems, here is how the conversions work. Before we jump into each model type, lets look at what the basics are, with the following calculations. . . . . There are s number of splits (hyper) per physical device. There are n number of

Symmetrix device masking or VCM devices are Symmetrix devices that have been masked for visibility to certain hosts. The device masking database (VCMDB), which holds device masking records, typically resides on a small disk device (such as a 48-cylinder, 24 MB device). For more information, see the EMC Solutions Enabler Symmetrix Device Masking CLI Product Guide.

Since Enginuity Version 5568, devices can be configured to be dynamic RDF Capable Devices. Dynamic RDF enables you to create , delete & swap SRDF pairs while the symmetrix array in operation. And you can establish SRDF device pairs from non-SRDF devices, & then syncronize and manage them in the same way as you configured SRDF pairs. The Dynamic RDF configuration

    Common Internet File System (CIFS) is a protocol that lets programs make requests for files and services on remote computers on the Internet. CIFS uses the client/server  programming model. A client program makes a request of a server program (usually in another computer) for access to a file or to pass a message to a program that runs in the server computer. The server
