• 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.

• 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.

• SAN Best Practices for VSphere

  Hello world!

  I am new on VSphere and newest on the SAN, but I want to make all things right from the beginning. Where can I find a best practice document on the SAN and VSphere? I am looking for some recommendations on the design and deployment of SAN. What size for VMFS? How many virtual machines are recommended?

  I hope some of you can help me. Thanks for taking your time to read this

  Good bye.

  Are what types of SAN you using FC/iSCSI/NFS? Nor the means, you should architect your storage space redundant with several storage processors connected to several switches / HBA several guests. For the size of the LUN, between 400-600 GB would be a good thing and not put too many guests on a single LUN to prevent the conflict in booking iSCSI and tend to be I/O-bound and result in "fly". Standard rule is 4-6 VMs by heart and it depends on the types of loaded applications. Always start with 1 vCPU and 1024 MB of ram, started by and increase if necessary. Not recommended to use extensions to within the data store so plan accordingly. If you use RDM to sql, exchange or file server purposes plan accordingly because it has limits on the mode to use. I read VMware best practices guides and use your practices best sellers as well. Good luck in your design!

• OEM 12 c Best Practice follow-up 11.1 DB RAC env. + datagurd

  OEM 12 c 5 release is the only monitoring in our environment... is there a better model of practice on what aspects need to be monitored and their default values?
  

  This doc for 12 c DB is very useful, it's best practices for high availability. They talk a lot about the RAC/DG monitoring.  https://docs.Oracle.com/database/121/HABPT/monitor.htm#HABPT003

  version 11.2 is here https://docs.oracle.com/cd/E11882_01/server.112/e10803/monitor.htm#g1011041, I read them both though, as there are some new features in version 12 c who may still apply to 11 g.

  Regarding the parameters/models go, if you create a template of the target type (monitoring sc_results.php-> create-select target type-> type > select category/target), this will include all the parameters of the type of target (including the CEO) and as close as you'll have to 'default thresholds' Oracle.  It is the best branch of the teams effort produced.   Of course, they will not be perfect for everyone, but it's a starting point!

• What is the best practice for a 'regular' Server VMware and VDI environment?

  What is the best practice for a "regular" VMware Server and VDI environment?   A single environment (ESXi and SAN) can accommodate two if it is a whole new configuration?  Or even better to keep separate?

  Enjoying inputs.

  Quick and dirty answer is that "it depends."

  serioulsy, it depends really two things budget and IO.  If you had the money for two without then buy two and don't have to host your server environment and the other for VDI desktop, their IO profiles are completely different.

  If this is not the case, try to keep each type of use for their own dedicated LUN.

  What would be the best practice to migrate all the guests and the hosts on the server main vCentre.

  I choose one of the vCenters, unplug and remove hosts from the other and connect them to those elected. Configure the cluster after that (all in the same or keep the separation of the group, which I think is the best)

  You can also use related modes.

• Best practices using clusters to create the queue/notifier/bundles?

  I'm in a block diagram, a queue, the notifier and several instances of cluster of bundle

  that all use the same data structure.   There is a typedef of cluster for the data structure.

  Of course, each of these objects (define the queue, set notifier, bundle)

  you want to know how do you define the cluster.

  What is considered best practices?

  (1) create a dummy instance of the cluster across data structure

  definition is necessary (and hide all on the public Service)

  (2) create only one instance and son at all places, it is necessary

  But there is no stream on this thread: it's only the cluster * definition *.

  which is used, so this seems to clutter the comic.

  (3) create only one instance of the cluster control and use local variables

  everywhere else the definition of cluster is required.  It's _value_ is never

  assigned or given read-so no problem with race conditions.

  (4) another way?

  If you were to clean up someone else's code, how do you expect

  See this Treaty?

  It occurred to me during this writing that here where I

  "unbundle...... code bundle" I could wire the original beam to the

  the two "unbundle" and "bundle" - but that would be too complicated

  and the size of the comics with useless thread?

  Thank you and best regards,

  -- J.

  Hi Jeff,

  I think that this question is about "sharing" the typedef and not how share data (?)  If the cluster control is registered as a typedef (or a strict typedef) but NOT SIMPLY as a CONTROL, then when a Diagram-constant of the typedef is created, it will be updated when you update the .ctl typedef!  (and there is no FP control to hide )  Of course if the typdef is already available "close" if necessary, you will be able to use instead - save a spacer of diagram.

  See you soon.

• VMware Performance event triggers use case issues.

  1) can event Performance adapter CPO VMware triggers and their

  Attributes of the SAMPLE SIZE, INTERVAL and CONDITIONS be configured

  for the following use cases?

  (2) event VMWare Performance triggers may be CORRELATED?  and if so it would take to satisfy the use case?

  (3) an additional performance monitoring tool needed to satisy the use case? :

  If a VM CPU or RAM was 80% for 2 hours then trigger a workflow

  and

  If a VM CPU or RAM was 60% for X days and then trigger a workflow

  First, I will describe how you can instrument a correlation method, but in the end, I'm not sure it's really necessary for use cases described.

  To correlate the performance VMware on a designated period events, you would create a process correlation that follows the underlying the performance event and decides to trigger the process wished triggered when correlated event is detected or not.

  Here's how it works.

  First, create a global table with three columns:

  (1) virtual path Machine

  (2) County of consecutive trigger

  (3) latest trip time

  Create a process that is triggered by a performance event VMware (for example memory Avg > 80%) where you can set the size of the sample and an interval that is logical view of the period of interest (2 hours or X days). For example, a sample of 10 and 30 seconds (5 minutes) are a slice of reasonable time to vCenter for 2 hours. As a result, requiring 24 consecutive triggers to trigger the real event of interest. (divided by 5 minutes to 2 hours)

  In other words, the formula is:

  Sample size * interval / calendar = consecutive trigger Count

  The correlation process triggered by the gross VMware event does the following:

  (1) if there is no existing entry in the overall table for the virtual machine, add the entry to table with count = 1 and current time

  (2) if the entry exists, check the current time against the last trigger time

  (a) if it is the next interval, for example, the time now is 12:15 and triggered last time was 12:10 (see note below).

  Incrementing counter and trip together last time

  If count = 24, then run the process that manages the "VM memory Avg > 80% for at least 2 hours' and remove the entry from the table.

  If count< 24,="" the="" process="" exits="" having="" only="" incremented="" the="" counter="" and="" set="" the="" last="" trigger="">

  (b) if the current time is > that last trigger time slice schedule (+ a little padding), set the counter to 1

  Note: When comparing the time of w/last time running, you should cover to consider delay light treatment in order to compare now< last-time+(time="" slice*2).="" anything="" less="" than="" 10="" minutes="" in="" this="" case="" would="" be="" considered="" a="" consecutive="" trigger.="" you="" could="" also="" compare="" current-time="">< last-time+time-slice+1,="" which="" is="" probably="" also="">

  Now, after going through all that, you don't have to the process of correlation after all. Simply adjust your sample size to be large enough to accommodate your deadline and you launch your handler directly without having to correlate. So for the 2 hour window, simply create a sample size 240 (* 30 seconds = 2 hours). This may or may not work depending on how performance indicators have been set up on the server (sample size, intervals and how much is saved). You can define your own samples and multiples of these configured values intervals (so be careful and see VMware documentation when he resorts to such measures)

  You can see that I have described everything first correlation method is more reliable, especially for longer periods such as X days (where you need to taste every hour instead of every 5 minutes).

  In any case, I think you can do what's needed without external control, but will require experimentation and a deeper knowledge of the works of performance for ESX metric sampling.

• Best practices for color use in Adobe CC?

  Hi all

  Is there an article that describes the best practices for use of color in Adobe CC?

  I produce a mixture of viewing online (PDF, for the most part) and real world print projects - often with the obligation for both. I recently updated my PANTONE + bridge books for the first time in ages and I am suddenly confused by the use of Lab colors in the Adobe Suite (Illustrator and InDesign).

  Everything I found online, looks like Lab color mode preferred to use because it is device independent. And perceptual (on screen), it looks much closer to the color, it is trying to represent. But when I mark a Spot color Illustrator rectangle using laboratory coordinates, to the sides of a rectangle using PANTONE + bridge CP and then export it to PDF, the version of CP to mix CMYK color corresponds exactly to my Pantone book - while the version of laboratory (after converted to CMYK using the ink Manager) is far away.

  I have this fantasy to manage only a single Illustrator or InDesign file for both worlds (PDF) printed and online. Is not possible in practice?

  Any info describing the basic definitions of the color modes - or even a book tracing more than use them in the real world - would be much appreciated!

  Thank you

  Bob

  Here are a few best practices you can already do.

  1 make sure that your color settings are synchronized on all applications.

  2. use a CMYK profile appropriate for your print output. Lab spot colors convert to CMYK values based on the CMYK icc profile.

  3. include icc profiles when save or export pdf files

  In theory, your imagination is possible today. It requires color management and the use of icc profiles. You can place RGB images in InDesign and use Pantone colors in your objects. The problem lies in the printers. If a printer uses a RIP with built in Pantone library, the colors will match when printing. Unfortunately, this kind of CUT is more expensive and not enough printers use them. Most of them is always manually approximate CMYK values composition given Pantone colors.
