• 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.

• Oracle on NetApp - white paper best practices?

  I thought I saw a nice whitepaper "best practices" that Oracle published to operate the RDBMS on NetApp.
  
  But I can't seem to find now. Does anyone have a link?
  
  (I access Metalink if it is there, but my search didn't find it).
  
  Thank you!

• vSpere 5 Networking of best practices for the use of 4 to 1 GB NIC?

  Hello

  I'm looking for a networking of best practices for the use of 4-1 GB NIC with vSphere 5. I know there are a lot of good practice using 10 GB, but our current config does support only 1 GB. I need to include the management, vMotion, Virtual Machine (VM) and iSCSi. If there are others you would recommend, please let me know.

  I found a diagram that resembles what I need, but it's for 10 GB. I think it works...

  (I had this pattern HERE - rights go to Paul Kelly)

  My next question is how much of a traffic load is each object take through the network, percentage wise?

  For example, 'Management' is very small and the only time where it is in use is during the installation of the agent. Then it uses 70%.

  I need the percentage of bandwidth, if possible.

  If anyone out there can help me, that would be so awesome.

  Thank you!

  -Erich

  Without knowing your environment, it would be impossible to give you an idea of the uses of bandwidth.

  That said if you had about 10-15 virtual machines per host with this configuration, you should be fine.

• best practices online redundant redologs

  DBS Oracle under Unix without ASM
  
  DBs some have oracle only available file system on the unix machine & have a single file redolog available online, I was wondering what would be the best practice them on redundant?
  
  I know that if I have multiple oracle file systems, I can extend their there. but with a single file system, I can create a redolog more and put it on the same file system.

  If you have a single file system or file systems normally makes no difference, but it is rather the disc behind the file systems that count. If two file systems are spread among the same disc which buy you two file systems. Oracle recommends that you multiplex online redo log files I know a shop that works with a single non-multiplied set of newspapers in restoration online and in 15 years they have never lost a. They use mirrored disks.

  It comes down to performance vs risk. What is the risk of losing a redo online newspapers verse how a load of performance having a cost fixed multiplex.

• Design by using NetApp's best practices

  I am preparing for my VCP5 and I read the new book by Scott Lowe. the book describes how the traffic should be isolated. your vMotion, vmkernal, etc., but in many organizations, I see the NetApp with some of data warehouses and a few LUNS to CIFS share LUNS. I guess you can have your vmMotion on a VLAN separated, but would not safer just configure a windows VM file server to host your files? In freenas and openfiler forums, they stress is not to run their software in virtual machines in a production environment.   Physical separation would be better then just a VLAN? I was inking and correct me if I'm wrong. I think the CIFS shares in a virtual hosting machine would SAN, vMotion, vmkernal, most reliable if you have redundant switches on both sides VMware hosts. So if your kernel switches drop your vmware environment will not drop.

  > traffic must be isolated.

  Yes, the network traffic must be split on networks separated for various reasons, including performance and safety.

  > NetApps with MON a few for data warehouses and a few LUNS to CIFS share.

  Yes, if you have a NetApp file server you can block-level storage server as FCP or iSCSI, CIFS or NFS file-level storage.

  > I guess you can have your vmMotion on a VLAN separated, but would not safer just configure a windows VM file server to host your files?

  OK, you lost me.  Yes, you must separate the vMotion traffic to enhance the performance and because the vMotion traffic is not encrypted.

  I don't see where you're going for vMotion to a Windows file server?

  However, if you are referring to, why don't you your NetApp instead of Windows CIFS Server:

  You don't need to patch and reboot the NetApp at least once a month.

  Performance is better

  You don't need to buy a Windows license and then maintain Windows

  Snapshots.  NetApp has the best shots in the business.  When your Windows I/O high, or just typing box because it of Tuesday and removes all of your VSS snapshots you really wish you had a NetApp.

  > In the forums of freenas and openfiler, they stress is not to run their software in virtual machines in a production environment.

  Note that there are a ton of storage there equipment running as VMs and server NFS for shared storage, including left and they have been stable for years.

  > Physical separation would be better then just a VLAN?

  Yes, if you have the infrastructure.  When it comes to the first time I've seen reference you VLAN?  Are you talking about now the NetApp as the series 2020 with two network cards where you need to carry all traffic (managent, CIFS and iSCSI) through them via VLAN?

  Like this: http://sostechblog.com/2012/01/08/netapp-fas2xxx-fas3xxx-2-nic-ethernet-scheme/

  > I was inking and correct me if I'm wrong. I think the CIFS shares in a virtual hosting machine would SAN, vMotion, vmkernal, most reliable

  CIFS is nothting to do with SAN, vMotion or VMkernel.  CIFS (SMB) is the protocol used mainly by Windows file sharing

  > If you have redundant switches on both sides of the VMware hosts. So if your kernel switches drop your vmware environment will not drop.

  You always want to redundant switches.  No single point of failure is the best practice.

• Best practices with two natachasery

  Hello

  I'll put up a small environment Vi3 with two HP DL380 G5 machines ESX and NFS on NetApp for storage. This must be installed in a field of laboratory and serve as both a learning platform Vi3, we, the admins and a test environment for some of our customers run their own virtual machines with the test software and others. For this purpose, safety is a higher priority than redundancy, roughly equal performance. What is a decent way to implement the two natachasery for this configuration?

  vSwitch0 and pNIC1:

  -VMkernel (vMotion and NFS)

  -Console service

  vSwitch1 and pNIC2:

  -VM network

  This would obviously no redundancy (not counting the vMotion between hosts) but separate VM and non - VM traffic. Is there anything else I should be concerned?

  Thanks in advance,

  Daniel

  Hi Daniel,.

  Available seems very well, simply create a trade.

  (Depends on the load, you might want to consider making another Nic dual or quad). I have 2 natachasery for virtual machines and 2 for NFS...

  Here is a great link to the blog created by Texiwill: (best practices for up to 8 NIC explained)

• 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.

• 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 Practice Guide for stacked N3024 switches

  Is there a guide to BP for the configuration of the 2 N3024s stacked for the connections to the server, or is the same eql iscsi configuration guide.

  I'm trying to:

  1) reduce to a single point of failure for rack.

  (2) make good use of LACP for 2 and 4 nic server connections

  (3) use a 5224 with it's 1 lacp-> n3024s for devices of unique connection point (ie: internet router)

  TIA

  Jim...

  Barrett pointed out many of the common practices suggested for stacking. The best practice is to use a loop for stacking and distributing your LAG on multiple switches in the stack, are not specific to any brand or model of the switch. The steps described in the guides of the user or the white papers generally what is the recommended configuration.
  http://Dell.to/20sLnnc

  Many of the best practices scenarios will change of network-to-network based around what is currently plugged into the switch, and the independent networks needs / requirements of business. This has created a scenario where the default settings on a switch are pre-programmed for what is optimal for a fresh switch. Then recommended are described in detail in white papers for specific and not centralized scenarios in a single document of best practices that attempts to cover all scenarios.

  Express.ypH N-series switches are:
  -RSTP is enabled by default.
  -Green eee-mode is disabled by default.
  -Frother is enabled by default.
  -Storm control is disabled by default.

  Then these things can change based on the towed gear and needs/desires of the whole of society.

  For example, Equallogic has several guides that recommendations of configuration detail to different switches.
  http://Dell.to/1ICQhFX

  Then on the side server, you would like to look more like the OS/server role. For example a whitepaper VMware that has some network settings proposed when running VMware in an iSCSI environment.
  http://bit.LY/2ach2I7

  I suggest making a list of the technology/hardware/software, which is used on the network. Then use this list to acquire white papers for specific areas. Then use these white papers best practices in order to ensure the switch configuration is optimal for the task required by the network.

• Is have RAID (1 + 0) so that Failgroups for all ASM ASM starts is a well-known best practice?

  Dear Experts,

  Is have RAID (1 + 0) so that Failgroups for all ASM ASM starts is a well-known best practice?

  Having both is the best practice

  • RAID (1 + 0)
  • ASM Failgroups for all ASM starts

  Thank you

  IVW

  You can create groups of ASM disks with normal or high redundancy or specify external redundancy. It depends on your reliability requirements and storage performance. Remember that ASM is not RAID and redundancy is the base file. ASM uses alternating devices. Oracle is generally recommended to have redundancy of storage. If you have RAID redundancy at the level of hardware controller or storage, Oracle recommends to configure ASM disks with external redundancy groups. Redundancy of the DSO is only between groups of disk failure and by default, each device's own failure group. Of course, you always want to make sure that you do not rely on redundancy of data between logical devices or partitions residing on a single physical unit. Compared to external RAID redundancy redundancy ASM using will give the DBA more control and transparency on the setting of the underlying.

• Dimension design best practices

  Hello

  I'm about to start a new project!

  Do you have ideas on best practices to define dimensions? A presentation or conference will help.

  I ask this question because it's kind of a mix between an art and a science.

  And the current metadata provided seems to have redundancy on their GL segments.

  I don't want to go and map each segment in each dimension, I think it would be counterproductive.

  Thank you for your comments

  Concerning

  You may be able to get some advice from the technical point of view by searching online or via the database administrator's guide.

  If you want to get this from the functional point of view, you will need professional help. The design will depend entirely on what are the needs of your business.

  Only thing I can say is ESSBASE and planning analytical solutions type applications so we shouldn't try to bring in great detail it is there is transactional system.

• Is there a best practice workflow?

  Hello

  I'm new to this first pro Capper.

  Is there a best practice for workflows?

  One of my challenges, or lack of understanding, is editing the files on the external hard drive. Is this OK to do, it causes problems or is it better to have the files on the iMac, and then when the project is completed transfer batch on the external hard drive?

  Thanks for your help!

  PrPro is a little hard on the equipment... it is seizing so many bits & pieces of the time here & there it is reading and/or rendered and all, that it can make points of congestion in the computer processing. Then... a default installation to date has been to have 4 to 6 'internal' on the computer discs, individually or in a stripped hardware RAID 0 and player programs/system/operating system. There are of course many are working on NAS (Network Attached Server) or these other means, with rather... Nice... external hardware.

  For external drives, those who are bound by (in order of preference by a throughput) were Thunderbolt, eSATA II, USB3... with up to recently the first two only really able to good use in a situation of reading/record with one exception: for the clips and 1080 and lower exports, USB3 was enough for one of the two one-way uses : media OR exports.

  Bill Gehrke ( http://ppbm7.com/index.php/tweakers-page ) and one frequently in forum Hardware ( https://forums.adobe.com/community/premiere/hardware_forum ) has tested a few discs SSD T1 Samsun lately and found capable even on USB3 a sustained flow such that there could be several parts of the workload PrPro on one project and change again very well. In addition, there are some internal readers it is used that have the speed to have whole projects on them... when connected via legal means in the computer. So I would check the Page the Hardware Forum and Tweaker for its latest hardware configurations & reader reviews for work on projects of PrPro.

• Best practices for a NFS data store

  I need to create a data store on a NAS and connect to some servers ESXi 5.0 as a NFS datastore.

  It will be used to host virtual machines less used.

  What are the best practices to create and connect a datastore NFS or networking and storage view bridges in order to get the best possible performance and decrease is not the overall performance of the network?

  Concerning

  Marius

  Create a new subnet of layer 2 for your NFS data warehouses and set it up on his own vSwitch with two uplinks in an active configuration / eve of reunification. Uplink should be variously patches in two distinct physical switches and the subnet must have the disabled bridge so that NFS traffic is not routable in other parts of your network. NFS export can be restricted to the IP address of storage host IP (address of the VM kernel port you created for NFS in the first step), or any address on that subnet. This configuration isolates traffic NFS for performance, ensures the security and redundancy. You should also consult your whitepapers of storage vendors for any specific recommendation of the seller.

  Data warehouses can be made available for the guests you wish and you can use Iometer to compare PAHO are / s and flow rate to see if it meets your expectations and requirements.
