• Nexus 1000v and vSwitch best practices

  I am working on the design of our vDS Nexus 1000v for use on HP BL490 G6 servers. 8 natachasery is allocated as follows:

  vmnic0, 1: management of ESXi, VSM-CTRL-PKT, VSM - MGT

  vmnic2, 3: vMotion

  vmnic4, 5: iSCSI, FT, Clustering heartbeats

  vmnic6, 7: data server and Client VM traffic

  Should I migrate all the natachasery to 1000v vDS, or should I let vmnic 0.1 on a regular vSwitch and others migrate to the vDS? If I migrate all the natachasery at the very least I would designate vmnic 0.1 as system so that traffic could elapse until the MSM could be reached. My inclination is to migrate all the natachasery, but I've seen elsewhere on comments in forums that the VSM associated networks and, possibly, the console ESX (i) are better let off of the vDS.

  Thoughts?

  Here is a best practice-how-to guide specific to 1000v & VC HP might be useful.

  See you soon,.

• HTML and CSS best practices for Eloqua?

  Hello Topliners community,

  My name is Ben and I am a Web Designer. Currently looking for guidance on best practices in HTML and CSS when you work with Eloqua. I am interested in best practices for email and landing pages.

  Thank you

  Ben

  For landing pages, you can use a bit of HTML, CSS, and Javascript like on any other page. For example, we use the Bootstrap on a couple of our Eloqua landing pages.

  Support for HTML and CSS is much more limited. It is one of the best resources I've seen for CSS support:

• creation of eBook and EPUB Best Practices guide

  I plan to convert the EPUB format for display on eReaders in my book, but I can't find a set of guidelines. I ran across a reference to a "EPUB best practices guide", but I was not able to find it. Anyhone knows where it is?

  My book is in InDesign CS5, and I was the creation of PDF files for the eBook version. I would be very interested in his comments on the advantages and disadvantages of the EPUB. I understand that the page size will be smaller (it is now 8.5 x 11) and images (there are many of them) will be online. Is there anything else I should know before I plunge into that?

  Thank you

• IOS VPN L2L, placement and discuss best practices

  We install an IOS router VPN on a for L2L 2651XM VPN bundle.

  I am trying to determine the best placement for the VPN router.

  We have Internet BR, then switch outside, Pix, then inside the switch.

  We have installed a card 4 ports in the Pix 515e to provide the DMZ interface, but have not yet configured all interfaces.

  L2L is B2B and we need so our traffic/internal network firewall/NAT.

  I have a switch for the DMZ if necessary for additional PSS.

  I recommend you to place the VPN router outside of the interface on the outside of the firewall. Ending inside the unencrypted VPN interface on port DMZ on the PIX, in this way, you can use the pix to control which internal servers users VPN can connect to.

  This way you can your traffic inside nat, but your VPN traffic to not cross a line of nat. Your VPN users also allow the pix to access your internet connection

  On the VPN router lock the outside as much as possible interface, if the IOS supports the functionality defined firewall and then use it.

• charge battery for the first time and the best practices for maintaining the life of the new PC laptop battery

  Received my first laptop as a gift today (Pavilion touchsmart 15-n287cl).  You need to know 1.  How long to charge it for the first time or first several times; 2 do you need to unload and reload between each use completely and how long should it take to charge an average before being used again.  3. Since no instructions is a good idea to leave it plugged when you use all the time or the battery should be removed to improve the conservation of life?

  Thank you in advance, it has taken a lot of time to migrate from the desktop.  Want it to be a positive experience.

  Hello

  Modern batteries and chargers are now smarter than you.

  1. you can plugin and immediately to use the machine, the machine will stop charge when the battery is fully charged.

  2. No, we don't need to unload completely between uses, then as above. The recommendation is sometimes we run machine on battery until that up to 10%.

  3. when using AC is a way to protect the unit during the failure of current, all of a sudden, leaving battery on laptop.

• What is the best practice to block through several layers sizes: hardware and hypervisor VM OS?

  The example below is not a real Setup, I work with, but should get the message. Here's my example of what I'm doing as a reference layer:

  (LAYER1) Hardware: The hardware RAID controller

  • -1 TB Volume configured in the 4K block size. (RAW)?

  
  

  (Layer2) Hypervisor: Data store ESXi

  • -1 TB of Raid Controller formatted with VMFS5 @ block size of 1 MB.

  
  

  Layer (3) the VM OS: Server 2008 R2 w/SQL

  • -100 GB virtual HD using NTFS @ 4 K for the OS block size.
  • -900 GB virtual HD set up using NTFS @ 64 K block size to store the SQL database.
  • 
    

  It seems that vmfs5 is limited to only having a block size of 1 MB. It would be preferable that all or part of the size of the blocks matched on different layers and why or why not? What are the different block sizes on other layers and performance? Could you suggest better alternative or best practices for the sample configuration above?

  If a San participated instead of a hardware on the host computer RAID controller, it would be better to store the vmdk of OS on the VMFS5 data store and create an iSCSI separated THAT LUN formatted to a block size of 64 K, then fix it with the initiator iSCSI in the operating system and which size to 64 K. The corresponding block sizes through layers increase performance or is it advisable? Any help answer and/or explaining best practices is greatly appreciated.

  itsolution,

  Thanks for the helpful response points.  I wrote a blog about this which I hope will help:

  Alignment of partition and blocks of size VMware 5 | blog.jgriffiths.org

  To answer your questions here, will:

  I have 1 TB of space (around) and create two Virutal Drives.

  Virtual Drive 1-10GB - to use for OS Hyper-visiere files

  Virtual Drive 2 - 990 GB - used for the storage of data/VM VMFS store

  The element size of default allocation on the Perc6 / i is 64 KB, but can be 8,16,32,64,128,256,512 or 1024 KB.

  What size block would you use table 1, which is where the real hyper-visiere will be installed?

  -> If you have two tables I would set the size of the block on the table of the hypervisor to 8 KB

  What block size that you use in table 2, which will be used as the VM data store in ESXi?

  ->, I'd go with 1024KO on VMFS 5 size

  -Do you want 1024KO to match the VMFS size which will be finally formatted on top he block?

  -> Yes

  * Consider that this database would eventually contain several virtual hard drives for each OS, database SQL, SQL logs formatted to NTFS to the recommended block, 4K, 8K, 64K size.

  -> The problem here is THAT VMFS will go with 1 MB, no matter what you're doing so sculpture located lower in the RAID will cause no problems but does not help either.  You have 4 k sectors on the disk.  RAID 1 MB, 1 MB invited VMFS, 4 k, 8K, 64 K.   Really, 64K gains are lost a little when the back-end storage is 1 MB.

  If the RAID stripe element size is set to 1 024 Ko so that it matches the VMFS 1 MB size of block, which would be better practice or is it indifferent?

  -> So that's 1024KB, or 4 KB chucks it doesn't really matter.

  What effect this has on the OS/Virtual HD and their sizes respective block installed on top of the tape and the size of block VMFS element?

  -> The effect is minimal on the performance but that exists.   It would be a lie to say that he didn't.

  I could be completely on the overall situation of the thought, but for me it seems that this must be some kind of correlation between the three different "layers" as I call it and a best practice in service.

  Hope that helps.  I'll tell you I ran block size SQL and Exchange time virtualized without any problem and without changing the operating system.  I just stuck with the standard size of microsoft.  I'd be much more concerned by the performance of the raid on your server controller.  They continue to do these things cheaper and cheaper with cache less and less.  If performance is the primary concern then I would consider a matrix or a RAID5/6 solution, or at least look at the amount of cache on your raid controller (reading is normally essential to the database)

  Just my two cents.

  Let me know if you have any additional questions.

  Thank you

• Best practices for vCenter 5.1 with Microsoft SQL Server 2008 R2

  I am looking for a best practices or really any documentation on configuring vCenter 5.1 with a SQL Server 2008 R2 database. I see that SQL Server 2008 R2 is supported, but that's all. Any help is appreciated.

  Unless you have a huge (and I mean huge) environment, the vCenter database in general is not that big of a deal or go-getter and was apparently not deemed worthy for some secret magic tips because of this.

  Standard SQL "best practices" and observe the standard installation documentation when deployment vCenter and you should be good to go.

  Some documents on the vCenter more in-depth database are here:

• NIC Teaming best practices

  Hello

  I have 1 server that has ports gigabit 8 inside. There will be 6 VLAN (including VLAN ID 4095) inside this ESX Server. Is it best practice to all gigabit 8 ports combine and link to vSwitch0 (default) and create the Group of ports by VLAN?

  Kind regards

  T.S.

  is absolutely not a stupid question

  Only for safety and performance. You can use configuration grouping in both cases. (2 NICs for sc and vmotion and 4 NICs for vlan tag vm)

  Keep this is to undertatnd that it is not an absolutely answare, but only a best practice, and that's OK as your design.

  I thank Alberto

• Best practices of the controller auto-Anchor

  Hi all

  I got confused with this configuration. I have 2 of Wlc. One is the internal controller and another set for the controller of the anchor (different subnet-DMZ area) for traffic comments. Where can I configure DHCP assignment for users of this... ? Must deal with to intervine Production controller in this dhcp or will I directly anchor to take care of everything... ? What is recommended?

  And any best practice doc is also available for this... ?

  Help, please...

  Thanks in advance.

  I usually use the WLC anchor for dhcp or the client will in fact have a dhcp server in the DMZ. I don't like to dig holes through the FW to dhcp unless I have to.

• Best practices for migrating workflows, actions, patterns between environments

  Hello

  Is there a better document practical to migrate workflows, actions and configuration between vco (-> production development) environments. We want to lock all the workflows/action/configurations in prod. Migration can be done manually through package. Is there something more than that.

  Thank you

  Create a Package using Orchestrator (change the drop-down list in the client in CREATING packages of access mode).

  Add the desired workflow, actions, resources and Configurations to the package. As they added, dependent actions, workflows, resources and configuration items will be detected and added to the package.

  Right-click on the package and either export or synchronize.

  Backup file system export package / archive. Then import it on the server (test or production) target.

  Synchronize to test or prod server when you are ready.

  In both cases, you will be presented with a comparison window that indicates what workflow / actions/configurations/resources will be updated on the target system.

  Make an element by element synchronize would be tedious and could miss dependencies packages are the preferred and recommended best practice.

  For additional info of workflow development lifecycle, see blog of Christophe here: http://bit.ly/vroWdlc

• Recommendations or best practices around change of the audio data on a network share?

  I have several users editing audio located on the same network share. They are always complaining about the performance.  Is it a best practice to edit audio located on the network?  I see so many issues (latency time, possible corruption, etc.) with that from the computer SCIENCE point of view, but I would like the opinion of those more familiar with the application and its best practices.  Thanks in advance.

  It's crazy! So that any audio to be edited with any degree of speed and security, it must be downloaded to a local computer, edited on that, and then the final result re-recorded on the network.

  You might as well do this anyway - at the time wherever you make a change, you store a local version of the file temp on the editing machine, and it has real save, or save as who turned to the network drive. Also, you would be working on a copy, the original is still available in the case of the vis - is up, and would not be the case if you edit the original files directly on the network, so it is intrinsically safer.

• AWM best practices 11g

  I will build a cube in AWM 11 g. It has 25 dimensions and some of the dimension tables has over 30 million records. I partitioned the cube on the dimension of time with the lowest level being months. One dimension took about 20 hours to build. I am now under the cube and makes more than 30 hours and its construction yet. I don't know what needs to be done to improve performance and just best practices in general. Thank you in advance. What is the recommended number of dimension to be used in the cube and are there recommendations as to how attributes affect the dim or hierarchies or how many measures to include in the cube. These cubes using OBIEE as the reporting tool.

  Thank you in advance.

  Hello

  25 dimensions are really much if you say that each cube is sized by each of them. With Oracle OLAP, you do not have these limits for a number of dimensions of a cube, but a typical good efficient cube can have 5 to 8 dimensions. If you analyze your business needs, you might be able to create smaller cubes much keep each cube to have 5 to 8 dimensions so that the loading process is much faster and suffocate.

  How many members you load dimension which takes 20 hours? You load a view or table? Also if you do a complete refresh of dimesion with synchronization and the cube is also loaded it takes a while to load but still 20 hours indicates that something is wrong here.

  Cube load performance depends on several facts:

  1 percent to precalculate.

  2. the cube dimension. How many members in each a dimension.

  3. What is the depth of the predetermined.

  4. how many measures you have in each cube.

  5. is partitioned cube? If Yes, what level, you need to maybe resolve and arrive at a correct level for the partition. How partititions.

  6. If your cubes are not partitioned, then you make series load that is eating all your time building.

  More you pre-computes, load cube takes more time, AW takes more space on the disk. A cube performance has good combination of precompute so that charge takes in your load limit and also query does not suffer.

• Upgrading ESX 3.0.2 for 3.5 - best practices and tips

  Hello

  I am currently managing a virtual environment running on ESX 3.0.2 and VC 2.0.2. I intend to upgrade this year to ESX 3.5 and VC 2.5. Anyone know where I can find information on best practices to upgrade and / or a document of instructions that will take me through the process? I had a glance on the VMWare Web site but cannot find anything.

  See you soon

  G

  I have attached a document with this information.

  First of all you must upgrade the VC and the database, then you must upgrade from ESX.

  Kind regards.
