EMC Storage Product Knowledge Sharing

There is available WWN decoder tool for EMC but I am going to discuss how to decode manually?Each Symmetrix SAF port, RAF port, EF ficon port or DAF port (DMX only) has a unique worldwide name (WWN). The WWN is associated with the Tachyon chip on the director. It was intended to remain unique per director so that the director can be accessed on a storage area network. The Symmetrix SAF/RAF/DAF/EF WWN is dependent on the Symmetrix serial number, the director number, the processor letter, and the port on the processor. When...

There are different type of SAN like IP SAN, NAS over SAN etc... We will discuss about Fibre Channel SAN. It gives you more option in order to manage and minimize downtime means reducing company cost.In general if you think storage environments, physical interfaces to storage consisted of parallel SCSI channels supporting a small number of SCSI devices. With Fibre Channel, the technology provides a means to implement robust storage area...

You have two fabrics running off of two switches. You'd like to make them one fabric. How to do that? For the most part, it's simply connecting the two switches via e_ports. Before doing that, however, realize there's several factors that can prevent them from mergingg Incompatible operating parameters such as RA_TOV and ED_TOV Duplicate domain IDs. Incompatible zoning configurations No principal switch (priority set to 255 on all switches) No response from the switch (hello sent every 30 seconds) ...
