How many Nexus 7000, Nexus 5000 and 2000 can a DCNM deployment support?
Hi Everyone,
Good Day! I would like to inquire how many Nexus boxes can a single DCNM deployment support given that we have the recommended server specifications?
Thanks and Regards,
Albert
Hi Lucien,
I have 2 pair of Nexus switches in my setup as follows
The first pair connection as below
==========================
Nexus 1 (configured with vpc 1)----- 2 connections------ 6500 catalyst sw1(po 9)
Nexus 2 (configured with vpc 1) ----- 2 connections------ 6500 catalyst sw2 (po9)
po2 on nexus pair for vpc peer link
Spanning tree on Nexus 1
po1 root fwd1 p2p peer stp
po2 desg fwd 1 vpc peer link
Spanning tree on Nexus 2
po1 altn blk1 p2p peer stp
po2 root fwd1 vpc peer link
The second pair connection
=====================
Nexus3 (configured with vpc 20 ) ------ 1 connection ------- 6500 catalyst sw1 (po20)
(configured with vpc 30) ------- 1 connection ------- 6500 catalyst sw2 (po30)
Nexus4 (configured with vpc 20) ----- 1connection ---- 6500 catalyst sw1 (po20)(stp guard root)
(configured with vpc 30) ----- 1 connection ----6500 catalyst sw2 (po30)(stp guard root)
po1 on nexus pair for vpc peer link
Spanning tree on Nexus 3
po1 desg fwd1 vpc peer link
po20 root fwd1 p2p peer stp
po30 altn blk1 p2p peer stp
Spanning tree on Nexus 4
po1 root fwd1 vpc peer link
po20 root fwd 1 p2p peer stp
po30 altn blk1 p2p peer stp
Problem Observed : High Ping response
Source server on 1st pair of switches ; Destination server on 2nd pair of switches
Ping response from 1st pair of switches to destination server : normal (between 1 to 3 ms)
Ping response fron 2nd pair of switches to source server : (jumping from 3ms to 100+ ms).
There is no errors or packet drops on any of the above ports, I cannot understand why the ping response is high for connections from second pair.

SAN Port-Channel between Nexus 5000 and Brocade 5100
I have a Nexus 5000 running in NPV mode connected to a Brocade 5100 FC switch using two FC ports on a native FC module in the Nexus 5000. I would like to configure these two physical links as one logical link using a SAN Port-Channel/ISL-Trunk. An ISL trunking license is already installed on the Brocade 5100. The Nexus 5000 is running NX-OS 4.2(1), the Brocade 5100 Fabric OS 6.20. Does anybody know if this is a supported configuration? If so, how can this be configured on the Nexus 5000 and the Brocade 5100? Thank you in advance for any comments.
Best regards,
FlorianI tried that and I could see the status light on the ports come on but it still showed not connected.
I configured another switch (a 3560) with the same config and the same layout with the fiber and I got the connection up on it. I just cant seem to get it on the 4506, would it be something with the supervisor? Could it be wanting to use the 10gb port instead of the 1gb ports? -
I don't know what happened. All of a sudden, my settings have been changed, my homepage, and EVERYTHING. No matter how many times I go in and change them again, the SAME pages open up when I start FireFox and I am constantly being asked if I want Yahoo as my start page and default search engine. I click the box 'do not ask me again' and it comes up EVERY TIME. I change things like I don't want history remembered, and when I reload FireFox again, it's back to the way it was BEFORE. EVERY SINGLE TIME. I don't know why this is happening, or how to fix it. What do I do??
I do not want to download another virus program.. I do not believe it is a virus. I am running the full version of Norton 360 and it is doing a daily scan. I have Windows 7, 64 bit OS.
This is very irritating !! If I wanted Yahoo I would ask for it ! -

How many types of Queues exists and how to identify them.
Hello
can anyone say How many types of Queues exists and how to identify them.
What does R3R* and CSA* stands for.
Regards,
divyaHi Divya,
The queues R3* and CSA* that you have specified are qRFC queues. qRFC queues are data queues which transport data to and fro different systems.
There are also the tRFC queues which are triggered whenever you make RFC calls to connect to another system.
Queues with prefix R3AD* - for delta download from R3->CRM
Queues with prefix R3AU* - for data upload from CRM->R3
Queues with prefix R3AR* - used to transfer data during request load from R3->CRM
Queues with prefix R3AI* - for initial load from R3->CRM
Queues with prefix CSA* - these are validation object specific queues used for processing/persisting data in CRM tables in a serialized manner. E.g. CSABUPA* for business partner,CSA_ORDER* for sales order etc.
You can administer and monitor the queues in trax. SMQR,SMQS.
Hope this helps you! Pls. do not forget to reward me some points.

I do backup with iCloud. I can't wait until the new iMac is available so that I can once again have my files in more than 1 location without needing to rely solely on the cloud.
I also rely on iTunes and my MacBook and Time Machine as well as backing up to iCloud. I know many users know have gone totally PC free, but I chose to use iCloud merely as my third backup.
I assume that the restore would result in my ability to open Pages and Numbers and fix the problem with deleting apps, but this would also mean that if my Numbers documents still exist solely within the app and are just not on iCloud for some reason that they would be gone forever. Is that right?
In a word, yes. In a little more detail.... When you restore from an iCloud backup, you must erase the device and start all over again. There is no other way to access the backup in iCloud without erasing the device. Consequently, you are starting all over again. Therefore, it would also be my assumption that Pages and Numbers will work again and that the deleting apps issues would be fixed as well.
If the documents are not in the backup, and you do not have a backup elsewhere, the documents could be gone forever. -
How can i decide how many dimensions are needed here.and which charactersti
Hi,
i am planning to create custom defined cube for sale order line item data. how can i decide how many dimensions are needed here.and which characterstics are suitable for that dimensions.
Thanks,
chandu.Hi Chandra,
How many dimensions are needed and which characteristics to be used totally depends upon the data model you are using.
for instance take an example of school.
teachers , students are the imp terms in this example .
you can choose these two as dimensions .
teacher's name , address , subject , class , designation etc can be its characteristics . and for students also the important terms describing them can be its characteristics.
for more understanding of the Dimensional Modeling you can refer to following link.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/6ce7b0a4-0b01-0010-52ac-a6e813c35a84
Hope It Helps .

How many devices (e.g. computer and laptop and ipad and iphone) can be linked to one iCloud account?
Thanks.At least 255 separate devices. But if you have a lot of users each with devices of their own, then they should each have separate user accounts, separate Apple IDs, and separate iTunes accounts; this will generally require at least one Apple ID/iCloud account per user.

How many megapixels is the front and back cam on ipad 2?
i wanna no how many MP are the fron and back cam in an ipad2 3G and Wifi version
While those numbers seem low its important to remember what the ipad cameras are for. They are not for taking photos. Who wants to hold up a huge ipad to take photos anyway when the chances are we all own a camera phone with much higher resolution or better yet, a real camera.
The cameras are designed for video. The front camera is good enough for facetime only while the rear can handle 720p video. Again, enough for a video call but thats about it. -
Is there any way to find a log of the send e-mail from ICloud.. to analyse how many email has been send and deleted within a day from send items
Thx Winston,
I can count the send item. But let me try to explain why did I ask this question.
I had a trouble in sending e-mails from icloud on 22/2 and when I saw in my send item there were no emails.
But the mesgs to whom I emailed received and out of which only few of them didn't got the email. So I wanted to know the log abt the outflow of the mesg with subject and the receipants email id and the list with attachment or not.
How and where will I get the information apart from send item and draft mesg and the outflow undelivered?
