    FICON History at Cisco. It is very important to note that this is not all of the FICON releases or features … that this hits some of the highlights.

    There are both more features and more releases that could have been added but the slide is already too cluttered.
  • The MDS 9710 is designed with room for growth. 3 fabric cards are required to support the 384 line rate 16G FC or 10G FCoE ports the platform supports today. As there are slots for 6 fabric cards, the platform can ultimately support 1.536 Tbps per slot, for 24 Tbps of total switching capacity, which will enable it to adapt to support future bandwidth requirements, such as 32G Fibre Channel or 40G FCoE, should the market require it.

    Today, a 48-port 16G FC module is available, with availability of a 48-port 10G FCoE module planned for later in the calendar year.

    Importantly, because all Cisco platforms for the data center run on Cisco NX-OS software and are managed by Cisco Prime Data Center Network Manager, customers who choose to migrate to the MDS 9710 will be able to use similar processes and procedures, without retraining staff.
  • Cisco takes the MDS heritage of non-stop, decade-long operations to the next level with N+1 fabrics, fully redundant components, and fault-tolerant architectural design.

    N+1 fabric redundancy design eliminates loss of bandwidth even if a fabric card should fail; competitive switches lose 50% of bandwidth if a fabric card fails.

    A fully loaded MDS 9710 requires 3 power supplies… ships with 6, with slots for 2 additional… enables N+1 power supply redundancy.

    Also enables N:N grid redundancy… connect to 2 separate power grids to keep operating even if a power grid should fail.

    MDS supports hitless/non-disruptive in-service software upgrades (ISSU) to keep the platform fully operational, even while performing updates to the operating system (Cisco NX-OS).

    Reducing failure domains, by distributing port channels across line cards, checking for corrupted frames at ingress as well as egress, and managing buffers in hardware helps to maintain consistent, line rate performance.
  • Discussion / Info about the slide and related topics – this is not a script to be read!

    The MDS 9710 has recently completed the IBM System Z / FICON Qualification testing. This means that the new code load of 6.2(5a) is ready to be deployed for mainframe datacenters.

    Three data types are used on the System Z mainframe.
    - First there is FCP that can be used when the Linux operating system is run on the mainframe – whether in an LPAR or under the VM operating system.
    - FICON is the evolution of ESCON which was the evolution of BUS and TAG … applications use data flows and structures called CCWs (channel command words) to communicate.
    One of the beauties of FICON is that channel programs / applications that were written for older link types (ESCON, Bus and Tag) still work for FICON. FICON is defined in FC-SB2
    and above from the T11.
    High Performance FICON is the newest generation of System Z communications. This is governed by FC-SB5 at the T11. HPF is an FCP-like protocol that applications can choose
    to exploit by changing their programs. High Performance FICON is where IBM is spending their time on performance enhancements around the System Z.
  • Discussion / Info about the slide and related topics – this is not a script to be read!

    The MDS 9710 carries forward almost all features of the MDS 9513.
    - VSANs – all know why these are good. There is a limit of 8 FICON VSANs per MDS 9710. To the System Z, each FICON VSAN looks like a different box since
    they have different serial numbers. For intermix customers, VSANs should be used for separating the FICON workload from the Open Systems workload.
    Intermix in FICON environments (ie. Open systems and FICON on same director) spans a range of implementation. There are a LOT of customers that put Open
    systems for FICON DASD replication (like PPRC or SRDF) in a VSAN on FICON directors. It is also common to see an Open VSAN for Linux workload on the
    System Z being a VSAN that shares an MDS with FICON. There are many less complete consolidation customers .ie Customers who run all of their Open workloads
    on the same physical directors as their FICON in entirety.
    - Management – DCNM, DCNM SAN, and Device Manager all support FICON on the MDS 9710. There are varying levels of integration with DM being the highest –
    where FICON information and configuration support is completely built in and intuitive. FICON also has an IBM-proprietary management interface that we implement
    based on an IBM specification called CUP (Control Unit Port). On the MDS, this is a software interface that talks to the System Z in-band through a FICON channel.
    CUP can be used to manage the director (bring ports up and down, allow and restrict who can talk to each other (on the same director), etc. CUP also allows the
    Mainframe to talk to the director and gather port statistics for the director that are then FED into the mainframe performance reporting tool(s).
    - On the MDS 9710, there is support for the full range of FICON ports allowed by the architecture. The FICON port address is a 1 byte field that tells the FICON address
    for a particular connected host, disk, or tape. MDS FICON port addresses can be from 0x00 – 0xFD. 0XFE us reserved for use by the CUP device and 0xFF is restricted.
    This means that the most ports allowed in a FICON VSAN are 254. All FICON port addresses are virtual – they can be assigned from Device Manager or the CLI and
    duplicate port addresses are not allowed in the same FICON VSAN.
    - The MDS 9710 supports full line-rate 16G FC protocol. 16G FICON is supported for ISLs carrying FICON VSANs. As there are no shipping 16G FICON adapters at
    this point, all real devices only login to the fabric as 8G ports.
