Businesses today need to replicate and distribute data on a global scale.  One technology that enables remote replication and disaster recovery solutions over Wide Area Networks (WAN) is SAN Extension.

In basic terms, SAN Extension connects switches between two sites over distance.  A popular SAN Extension deployment method uses Fibre Channel over IP or “FCiP”.  FCiP extends the inherent distance limitations of Fibre Channel and FICON® storage solutions.

What makes FCiP so great?
In simple terms, because Fibre Channel data is traveling (or tunneling) over traditional IP networks, FCiP can take advantage of the many features of TCP/IP.  These features include TCP’s reliable transmission service, hardware-based encryption known as IP Security (IP Sec), hardware-based compression which helps with link performance and port aggregation technologies to name a few.

This month, the Dell EMC Connectrix brand extends its SAN Extension offering with the addition of a new FCiP SAN Extension Module for the Connectrix MDS 9700 enterprise director series.  This new 24/10 port module supports all MDS advanced features including Inter-VSAN Routing which eliminates the need for external routing appliances in an existing SAN.

Are you thinking about SAN migration? Don’t go it alone

You’re a storage administrator.  You double as the storage network administrator.  Your company now relies heavily on server virtualization and now they’re rapidly moving to solid state drives and talking about transitioning some applications to “the cloud”.  All three of these technologies increase the need for low latency and high capacity network bandwidth.  You’re running an 8Gb/s Fibre Channel SAN and you’re feeling that the burden of these technologies is shifting to the network.  You think, “Can I really migrate the SAN by myself?”

SAN Migration can be a complex undertaking, but now you don’t need to go it alone.  Dell EMC has a new Professional Services offering that helps you complete your transition to today’s Modern Data Center.

 

The Dell EMC SAN Migration Service helps you replace existing SAN equipment using state of the art tools, with a fast and reliable storage networking environment that will deliver the bandwidth requirements imposed by server virtualization, all flash storage systems and cloud computing.

Storage Networking Performance Matters For Mainframe FICON Environments

A flashback to working in a house of cards…

My first role in IT was working in a data center of a reinsurance company as a Computer Operator.  I was responsible for running the company’s reporting programs on the UNIVersal Automatic Computer or “UNIVAC” mainframe.   To run a program on the UNIVAC mainframe, I’d go to the “Program Closet” and grab the pertinent program, which was a stack of punched cards, and then I’d feed the cards through the UNIVAC card reader and the report would be created.  Fun!

punchcards stacked
Not fun…sometimes a card, which represents a line of code or an instruction, would get damaged and I’d have to recreate it using a keypunch machine.  If the card were severely damaged, I’d have to go to the “Source Code Closet”.  The Source Code Closet contained the Master Program Decks.  Using the card from the Master Program Deck, I’d carefully replicate the damaged card by typing the instruction using the keypunch machine and then I’d rerun the operating deck through the card reader to produce the report.    Memories…

 Flash-forward to 2016; the cards are gone and the mainframe game has changed
Mainframe customers are expanding the role of their highly secure environments to repositories of enterprise data for web servers and web-based application services.  Every day more and more transactions originate from mobile devices that end up at mainframes for retail purchase transactional recording.   The number of transactions occurring daily along with traditional online transactions is in the millions and growing with no end in sight.

Bottom line–the mainframe has evolved to be the platform of record for 3rd platform applications. (more…)

Connectivity Matters For All Flash Storage Environments

Flash is transforming the data center but storage speeds mean nothing if I/O bottle necks prevent businesses from achieving its potential ’Why?  Think about high-speed train travel.  You can’t just buy a fleet of high-speed engines and send them out on rails built for more moderate speeds.  Likewise, a move to all flash storage should include a review of network decisions made in the years of spinning discs.

All Flash Storage Networking Requirements – Can You Say “Fibre Channel”?
Flash-based storage requires a network that is deterministic with low latencies and is easy to manage.  Fibre Channel has always delivered low latency, deterministic behavior, scalability and reliability.  Fibre Channel also has a higher assumed quality of service and provides six 9s reliability.   Fibre Channel was designed to use the Layer 2 network protocol, which requires less CPU utilization to encapsulate a payload than is required by storage over IP networks, which means the architecture of Fibre Channel itself provides inherent value.
