Fabric zoning best practices (new FC)

I'm new to CF (we are an iSCSI store), but I'm learning to my DCD. I read on different blog posts on zoning, which on the whole I think logical. I came across this blog post and am a little confused by the diagram:

http://vmfocus.com/2012/05/31/fabric-zoning-best-practices/

If you look at the chart it is logical, but higher than that, look at the text:

http://vmfocus.files.WordPress.com/2012/05/capture.PNG

E1 to S1 via Fabric Switch 1

E1 to S3 via Fabric Switch 2

E2 to S2 switch fabric 1

E2 to S4 via Fabric Switch 2

Via Fabric Switch S1 E3 1

E3 to S3 via Fabric Switch 2

E4 in the S2 switch fabric 1

E4 to S4 via Fabric Switch 2


How can connect to the same physical port on the HBA to switch 2? Is the text in the wrong article? I presume to know more than any zoning CF topic but I do not see how E1 can be plugged in more than one switch.


Totally confused...

Using my amazing art skills, I drew a diagram for you:

A high level view of fiber channel SAN would look like incredibly similar, if not identical to your iSCSI network. The text is just describing the logical connections, different server ports can do, such as ethernet. Let me know if it it clears, or I'll go into details with what you want.

  • What are the best practices for a new employee to learn inside the instance of their business of Eloqua as efficiently as possible?

    We have companies everything changed at some point in our lives. And we all go through the process in the first weeks, where you feel new and are just trying to figure out how not to get lost on your way in the mornings.

    On top of that, trying to familiarize yourself with your new company Eloqua instance can be a daunting task, especially if it's a large organization.

    What are the best practices for new employees to learn as efficiently and effectively as possible?

    I am in this situation right now. Moved to a much larger organization. It is a huge task trying to understand all the ins and outs not only society, but also of the eloqua instance, especially when she is complex with many points of integration. I find that most of the learning happens when I really go do the work. I spent a ton of time going through the programs, documentation, integrations, etc., but after awhile, it's all just words on a page and not absorbed.

    The biggest thing that I recommend is to learn how and why things are made the way they are currently, ask lots of questions, don't assume not that things work the same as they did with your previous employer.

    Download some base in place level benchmarks to demonstrate additional improvement.

    Make a list of tasks in the long term. As a new pair of eyes, make a list of things you'd like to improve.

  • New to ESXi ESXi installation USB or local disks operation best practices?

    I'm new to Vmware and run a small store, what is the best practice or best method to install the OS ESXi.  I currently have a few that I have installed on the usb stick on the server Board.  After some research it would be better to have two small drives SSD that I can raid with the operating system, then another RAID for the VM data store.  USB is a single source of failure.

    Thank you

    Mike

    Hello

    Having the internal hard drives in RAID1 for the o/s will certainly to avoid a single point of failure, as you pointed out correctly. At present the death of your USB key, your host problems quite quickly, and you will need to get a new one and re-install again. You could save your good host configuration and realistically - it does take too long to rebuild a crowd if he dies. Lose other stuff like network configurations and others would however be a pain!

    I think I have two SSD internal drives in RAID1 for the o/s is probably overkill. You will have an advantage any speed of startup, but realistically most of the servers restart everything often and once that ESXi is in place and operational it is very little activity on the disks, a config updates every so often and so on. I'd be inclined to use a SSD to create a Cache of the host for the swap drive, like that you can actually use the SSD and get more performance for your money.

    Many manufacturers (like Dell) use internal SD cards in RAID1. While SD cards are not known to be very robust, because of the congestion of ESXi and the minimum number of necessary paperwork once installed initially, it makes a less expensive alternative to business class for the o/s disks.

    In regards to your data warehouses, having an internal RAID your local disks is best if you use a stand-alone host with no storage attached to the network. You always have the problem of failure of the host if.

    See you soon,.

  • New to ColdFusion - Question about best practices

    Hello.

    I've been programming in Java / c# / PHP for the past two years or so, and as of late have really taken taste to ColdFusion.

    The question I have is around the effective separation of the code, and if there are any best practices that are preached by using this language. While I was learning Java, I was taught that it is better to have several layers in your code; example: Front end (JSP or ASP)-> Business Objects-> support-> database. All the code I've written using these three languages followed this simple structure, most of the time.

    As I dive deeper into ColdFusion, most of the examples I've seen of vetrans of this language really does incorporate a lot of separation. And I don't mean the simple ' here's what this function only "type of online examples where most of the code is written in a single file. I was able to see the projects that were created with this language.

    I work with a few developers who have written in ColdFusion for a few years and put the question to them as well. Their response was something to the effect, ' I don't know if there is any recommended for this, but it really doesn't seem like there is really a problem, make calls like that. "

    I searched online for any type of best practices or discussions around that and have not seen much.

    I still consider myself a bit of a noobling when it comes to programming, but best practice is important to me for any language that I learn more about.

    Thanks for the help.

    You might want to take a look at a number of major frameworks available for

    ColdFusion.

    FW/1 II, model glue, CFWheels, ColdBox and Mach.  They do a great job of

    giving you a path for the separation of code, best practices, etc.

  • Best practices Apple ID

    I help the family members and others with their Apple products. Probably the problem number one revolves around Apple ID I saw users follow these steps:

    (1) share IDs among the members of the family, but then wonder why messages/contacts/calendar entries etc are all shared.

    (2) have several Apple IDs willy-nilly associated with seemingly random devices. The Apple ID is not used for anything.

    (3) forget passwords. They always forget passwords.

    (4) is that I don't really understand. They use an e-mail from another system (gmail.com, hotmail.com, etc) as their Apple ID. Invariably, they will use a different password for their Apple ID than the one they used for other email, so that they are constantly confused about which account to connect to.

    I have looked around for an article on best practices for creating and using Apple ID, but could not find such a position. So I thought I would throw a few suggestions. If anyone knows of a list or wants to suggest changes/additions please feel free. Here are the best practices for normal circumstances, i.e. not cooperate accounts etc.

    1. every person has exactly 1 Apple ID.

    2. do not share Apple ID - share content.

    3. do not use an email address of another counts as your Apple ID.

    4. When you create a new Apple ID, don't forget to complete the secondary information to https://appleid.apple.com/account/manage. It is EXTREMELY important questions your email of relief and security.

    5. the last step is to collect the information that you entered in a document and save to your computer AND print and store it somewhere safe.

    Suggestions?

    I agree with no. 3, it is no problem with using a addressed no iCloud as the primary ID, indeed, depending on where you set up your ID, you may have no choice but to.

  • TDMS & Diadem best practices: what happens if my mark has breaks/cuts?

    I created a LV2011 datalogging application that stores a lot of data to TDMS files.  The basic architecture is like this:

    Each channel has these properties:

    To = start time

    DT = sampling interval

    Channel values:

    Table 1 d of the DBL values

    After the start of datalogging, I still just by adding the string values.  And if the size of the file the PDM goes beyond 1 GB, I create a new file and try again.  The application runs continuously for days/weeks, so I get a lot of TDMS files.

    It works very well.  But now I need to change my system to allow the acquisition of data for pause/resume.  In other words, there will be breaks in the signal (probably from 30 seconds to 10 minutes).  I had originally considered two values for each point of registration as a XY Chart (value & timestamp) data.  But I am opposed to this principal in because according to me, it fills your hard drive unnecessarily (twice us much disk footprint for the same data?).

    Also, I've never used a tiara, but I want to ensure that my data can be easily opened and analyzed using DIAdem.

    My question: are there some best practices for the storage of signals that break/break like that?  I would just start a new record with a new time of departure (To) and tiara somehow "bind" these signals... for example, I know that it is a continuation of the same signal.

    Of course, I should install Diadem and play with him.  But I thought I would ask the experts on best practices, first of all, as I have no knowledge of DIAdem.

    Hi josborne;

    Do you plan to create a new PDM file whenever the acquisition stops and starts, or you were missing fewer sections store multiple power the same TDMS file?  The best way to manage the shift of date / time is to store a waveform per channel per section of power and use the channel property who hails from waveform TDMS data - if you are wiring table of orange floating point or a waveform Brown to the TDMS Write.vi "wf_start_time".  Tiara 2011 has the ability to easily access the time offset when it is stored in this property of channel (assuming that it is stored as a date/time and not as a DBL or a string).  If you have only one section of power by PDM file, I would certainly also add a 'DateTime' property at the file level.  If you want to store several sections of power in a single file, PDM, I would recommend using a separate group for each section of power.  Make sure that you store the following properties of the string in the TDMS file if you want information to flow naturally to DIAdem:

    'wf_xname '.
    'wf_xunit_string '.
    'wf_start_time '.
    'wf_start_offset '.
    'wf_increment '.

  • Material LV real-time Ethernet com best practices

    Hello

    I just started to learn the LV in real-time, and until I get a new cRIO I just played with a former PSC-2220.

    Everything works, I am reading the tutorals nice about RT and deployment/running example to this target applications.

    However, I don't know what is the best practice, the IP address of this device handling. For easy installation, after a device reset (and install the new RT runtimes, etc) I put just the HW to obtain the dynamic IP address of my router (DHCP). My laptop connects to the same router via wifi.

    However, since after a few resets the target Gets a new IP (192.168.0.102, previous IP was... (104), I have to manually change the IP address in my project. Is it possible that the LV auto detects the target in my project? In addition, it seems that MAX retains the old information and creates a new line for the same target... so I guess that if the problem persists, MAX is going to fill? See screenshots below.

    As a solution, I'll try to use static IP for the target, so it must always use the same IP address.

    What is the common procedure to avoid this kind of problems? Just using static IP? Or miss me him too something else here?

    Thank you!

    I just always use static IP addresses.  It avoids just all kinds of questions, especially if you have several systems on the same network.

  • AF best practices for video

    I'm using an EOS 7 d for 1080 p HD video shooting. New to SLR camera and digital video. I have watched several tutorials but do not yet have a good understanding of what the best practices for the development.

    If I put the camera in AI Servo it will auto focus if the subject is moving away or toward me with depress me back AF-ON or the shutter button? Or should I press one of these buttons to make the camera continues to focus?

    You know tutorials or video lessons that cross using update with the video?

    Thanks in advance!

    I don't know any tutorials, but more serious videographers say it is best to use only the manual focus.

    Trial and error is a good teacher, when it comes to video DSLR. You'll quickly learn that video Auto Focus is really bad with the 7 d and most of the people do not use it all together.

    The method that works for me is to use AF before the filming of the video and then adjust manually if you want to you to shoot the video. With the help of f/8 or f/11 to keep everything in short without having to keep the setting.

    More recent Canon DSLR's like the T4i, T5i, 70 d and SL1 have a "hybrid AF" that does a much better job of AF during video, but it is not yet as good as a camcorder

  • I would like to know the "best practices" for unplugging my computer permanently to the internet and other updates.

    Thank you for taking the time to read this. I would like to know the "best practices" for unplugging my computer permanently to the internet and other updates. I thought I would do a clean install of Windows XP, install my Microsoft Works again and nothing else. I would like to effectively transforming my computer into a word processor. He continues more and more slow. I get blue screen errors, once again. I received excellent Microsoft Support when it happened before, but since my computer is around 13 years, I think it is not worth the headache to try to remedy. I ran the Windows 7 Upgrade Advisor, and my computer would not be able to upgrade. Please, can someone tell me how to make it only a word processor without updates or internet connection? (I already have a new computer with Microsoft Windows 7 Home Premium, it's the computer that I use. The old computer is just sitting there and once a week or so I updates.) I appreciate your time, thank you!

  • Dell MD3620i connect to vmware - best practices

    Hello community,

    I bought a Dell MD3620i with 2 x ports Ethernet 10Gbase-T on each controller (2 x controllers).
    My vmware environment consists of 2 x ESXi hosts (each with 2ports x 1Gbase-T) and a HP Lefthand (also 1Gbase-T) storage. The switches I have are the Cisco3750 who have only 1Gbase-T Ethernet.
    I'll replace this HP storage with DELL storage.
    As I have never worked with stores of DELL, I need your help in answering my questions:

    1. What is the best practices to connect to vmware at the Dell MD3620i hosts?
    2. What is the process to create a LUN?
    3. can I create more LUNS on a single disk group? or is the best practice to create a LUN on a group?
    4. how to configure iSCSI 10GBase-T working on the 1 Gbit/s switch ports?
    5 is the best practice to connect the Dell MD3620i directly to vmware without switch hosts?
    6. the old iscsi on HP storage is in another network, I can do vmotion to move all the VMS in an iSCSI network to another, and then change the IP addresses iSCSI on vmware virtual machines uninterrupted hosts?
    7. can I combine the two iSCSI ports to an interface of 2 Gbps to conenct to the switch? I use two switches, so I want to connect each controller to each switch limit their interfaces to 2 Gbps. My Question is, would be controller switched to another controller if the Ethernet link is located on the switch? (in which case a single reboot switch)

    Tahnks in advanse!

    Basics of TCP/IP: a computer cannot connect to 2 different networks (isolated) (e.g. 2 directly attached the cables between the server and an iSCSI port SAN) who share the same subnet.

    The corruption of data is very likely if you share the same vlan for iSCSI, however, performance and overall reliability would be affected.

    With a MD3620i, here are some configuration scenarios using the factory default subnets (and for DAS configurations I have added 4 additional subnets):

    Single switch (not recommended because the switch becomes your single point of failure):

    Controller 0:

    iSCSI port 0: 192.168.130.101

    iSCSI port 1: 192.168.131.101

    iSCSI port 2: 192.168.132.101

    iSCSI port 4: 192.168.133.101

    Controller 1:

    iSCSI port 0: 192.168.130.102

    iSCSI port 1: 192.168.131.102

    iSCSI port 2: 192.168.132.102

    iSCSI port 4: 192.168.133.102

    Server 1:

    iSCSI NIC 0: 192.168.130.110

    iSCSI NIC 1: 192.168.131.110

    iSCSI NIC 2: 192.168.132.110

    iSCSI NIC 3: 192.168.133.110

    Server 2:

    All ports plug 1 switch (obviously).

    If you only want to use the 2 NICs for iSCSI, have new server 1 Server subnet 130 and 131 and the use of the server 2 132 and 133, 3 then uses 130 and 131. This distributes the load of the e/s between the ports of iSCSI on the SAN.

    Two switches (a VLAN for all iSCSI ports on this switch if):

    NOTE: Do NOT link switches together. This avoids problems that occur on a switch does not affect the other switch.

    Controller 0:

    iSCSI port 0: 192.168.130.101-> for switch 1

    iSCSI port 1: 192.168.131.101-> to switch 2

    iSCSI port 2: 192.168.132.101-> for switch 1

    iSCSI port 4: 192.168.133.101-> to switch 2

    Controller 1:

    iSCSI port 0: 192.168.130.102-> for switch 1

    iSCSI port 1: 192.168.131.102-> to switch 2

    iSCSI port 2: 192.168.132.102-> for switch 1

    iSCSI port 4: 192.168.133.102-> to switch 2

    Server 1:

    iSCSI NIC 0: 192.168.130.110-> for switch 1

    iSCSI NIC 1: 192.168.131.110-> to switch 2

    iSCSI NIC 2: 192.168.132.110-> for switch 1

    iSCSI NIC 3: 192.168.133.110-> to switch 2

    Server 2:

    Same note on the use of only 2 cards per server for iSCSI. In this configuration each server will always use two switches so that a failure of the switch should not take down your server iSCSI connectivity.

    Quad switches (or 2 VLAN on each of the 2 switches above):

    iSCSI port 0: 192.168.130.101-> for switch 1

    iSCSI port 1: 192.168.131.101-> to switch 2

    iSCSI port 2: 192.168.132.101-> switch 3

    iSCSI port 4: 192.168.133.101-> at 4 switch

    Controller 1:

    iSCSI port 0: 192.168.130.102-> for switch 1

    iSCSI port 1: 192.168.131.102-> to switch 2

    iSCSI port 2: 192.168.132.102-> switch 3

    iSCSI port 4: 192.168.133.102-> at 4 switch

    Server 1:

    iSCSI NIC 0: 192.168.130.110-> for switch 1

    iSCSI NIC 1: 192.168.131.110-> to switch 2

    iSCSI NIC 2: 192.168.132.110-> switch 3

    iSCSI NIC 3: 192.168.133.110-> at 4 switch

    Server 2:

    In this case using 2 NICs per server is the first server uses the first 2 switches and the second server uses the second series of switches.

    Join directly:

    iSCSI port 0: 192.168.130.101-> server iSCSI NIC 1 (on an example of 192.168.130.110 IP)

    iSCSI port 1: 192.168.131.101-> server iSCSI NIC 2 (on an example of 192.168.131.110 IP)

    iSCSI port 2: 192.168.132.101-> server iSCSI NIC 3 (on an example of 192.168.132.110 IP)

    iSCSI port 4: 192.168.133.101-> server iSCSI NIC 4 (on an example of 192.168.133.110 IP)

    Controller 1:

    iSCSI port 0: 192.168.134.102-> server iSCSI NIC 5 (on an example of 192.168.134.110 IP)

    iSCSI port 1: 192.168.135.102-> server iSCSI NIC 6 (on an example of 192.168.135.110 IP)

    iSCSI port 2: 192.168.136.102-> server iSCSI NIC 7 (on an example of 192.168.136.110 IP)

    iSCSI port 4: 192.168.137.102-> server iSCSI NIC 8 (on an example of 192.168.137.110 IP)

    I left just 4 subnets controller 1 on the '102' IPs for more easy changing future.

  • Best practices for the firmware update 40 + switches

    Hello.

    I need for firmware (and boot code) updated over 40 switches PowerConnect (mainly 5324).

    What is the best practice on that?

    I tried to download and install Dell OpenManage Network Manager, but it seems like an application of 'disorder' for someone who doesn't know. I threw a look at the demo of Dell for the application, but the quality is very bad and it is a version different than the one I downloaded (V3.0.1.15) you cannot use the guides directly.

    Are there other options that manual session opening, then TFTP the new firmware and boot code? Or can someone a link to a valid demo or documentation that can help me with the work?

    Thanks in advance.


  • Best practices for designing a view in PlayBook

    Hello world

    I'm new to BlackBerry PlayBook development and I would like to know how to make a user interface appropriate for playbook, what would be the best practice to do and it will be helpful to me if someone can post sample code here

    Thanks in advance

    A few tips:

    * Views extend Sprite

    * Views should be resizable, IE have a setSize() method

    * views should 'PIN' children at some edges of the screen, from when they are resized it runs correctly.

    * a parent class must listen to the scene for Event.RESIZE and call of resizing on the view.

    * Use the component of QNX, set if possible

    * Implement native controls, like sliding down to the options

    Is there for example some best practices how to modify this code to have pages and components with the same sizes in portrait and landscape? On presentation buttons size always 150 width and height 45 and wil containers have stageWidth and stageHeight.

    Thank you if someone could help with this problem

    Hello

    Try listening to a shift in focus screen with this code:

    stage.addEventListener(Event.RESIZE, onResizeHandler, false, 0, true);
    

    You can only change the width/height of your components to the event based on the width/height of the floor.

    I will guard against specifying specific sizes, if you want your code to work on devices BB10. I recommend using %'s.

    Kind regards

  • Best practices to move a volume

    Hello

    What is the best practice to move a volume to a PS4100 to another PS6100

    PS two are not in the same group.

    Today, we have a PS5000 which reproduce on the PS4100. The administrator create 2 volumes on the PS4100 (because there is not enough space on the PS5000).

    We will replace the PS5000 with a new PS6100XV, and we want to move the volume of the PS4100 to the new PS6100.

    What is easiest way to do this with minimal downtime on this volume?

    I think that it is best to create a replica of volume 2 of the PS4100 to the new PS6100, disconnect the volume of the PS4100 and put the volume on the PS6100 online. fix?

    Thank you

    You can replicate as you have described.  Depending on the host operating system it may be easier to do at the level of the host.   With VMware ESX, you can move live VMS using vMotion Storage.

  • Best practices for the restart of the nodes of the ISE?

    Hello community,

    I administer an ISE installation with two nodes (I'm not a specialist of the ISE, my job is simply to manage the user/mac-addresses... but now I have to move my ISE a VMWare Cluster nodes to another VMWare Cluster.

    (Both VMWare environments are connected to our network of the company, but are different environments. vMotion is not possible)

    I want to stop ISE02, move it to our new VMWare environment and start it again.

    That I could do this with our ISE01 node...

    Are there best practices to achieve this? (Stop request first, stopl replikation etc.) ?

    Can I really just reboot a node ISE - or I have consider something before I do this? After I did this?

    All tasks after reboot?

    Thanks for any answer!

    ISE01
    Administration, monitoring, Service policy
    PRI (A), DRY (M)

    ISE02
    Administration, monitoring, Service policy
    SEC (A), PRI (M)

    There is a lot to consider here.  If changing environments involves a change of IP address and IP extended, then your policies, profiles and DACL would also change among other things.  If this is the case, create a new VM ISE in the new environment in evaluation license using the and recreate the old environment deployment by using the address of the new environment scheme.  Then a new secondary node set rotation and enter it on the primary.  Once this is done, you can re - host license from your old environment on your new environment.  You can use this tool to re - host:

    https://Tools.Cisco.com/swift/LicensingUI/loadDemoLicensee?formid=3999

    If IP addressing is to stay the same, it becomes simpler.

    First and always, perform an operational backup and configuration.

    If the downtime is not a problem, or if you have a window of maintenance of an hour or so: just to close the two nodes.  Transfer to the new environment and light them, head node first, of course.

    If the downtime is a problem, stop the secondary node and transfer it to the new environment.  Start the secondary node and when he comes back, stop the main node.  Once that stopped services on the head node, promote the secondary node to the primary node.

    Transfer of the FORMER primary node to the new environment and turn it on.  She should play the role of secondary node.  If it is not the case, assign this role through the GUI.

    Remember, the proper way to shut down a node of ISE is:

    request stop ise

    Halt

    By using these commands, the risk of database corruption decreases by 90% (remember to always backup).
