VMWare - networking and ESXi installation questions

Hey all, hoping for some assistance on building my servers.
I am likely going with SuperMicro 2028R-E1CR24N due to cost and the fact that I can put Samsung Pro 845DC SSD drives in there and it will be covered under warranty (does anyone use SuperMicro today?), but am still considering HP DL Gen9 series servers because, well, they are HP and its always a slightly safer bet than SuperMicro...but the costs with SSD drives is just too high
Question 1.....
I am unsure whether to get 10GB RJ 45 NICs or the 10GB SFP+ NICs
Not sure between Intel 520X, 540, 560...etc.
The switches these servers will be plugging into will be Cisco 3750X switches, they currently don't have 10GB SFP+ modules yet but I could easily purchase though.
So I am unsure if SFP+ provides better and TRUE 10GB throughput and bandwidth? Or is RJ45 10gb NICs ok and I simply just plug them into the regular ports on the switch (I think they are set to auto/auto/1GB though?)
I also have the option for X540 Quad Port 10GBAse-T but unsure if I need it or how it could help me...
Question 2....
SuperMicro doesn't have slots for SD or MicroSD cards for the ESXi installation but they do have a 64GB Sata 6GB/s Disk on Module (MLC)..I know I don't need the space and it doesn't look like it needs one of the regular drivebays on the server for this, so will this be sufficient?
Does anyone use this today and how is the performance?
HP has slots for MicroSD cards...
Thanks all!

The minimum version, for both Windows 8 and 8.1, is ESXi 5.1
To upgrade, you need to upgrade at least one of your hosts to ESXi 5.1. To manage that host with vCenter, you will need to upgrade vCenter to 5.1 as well, which will manage your ESXi 5.0 and 5.1 hosts. See the following link for interoperability: http://partnerweb.vmware.com/comp_guide2/sim/interop_matrix.php
Here is the link to upgrade a host to ESXi 5.1:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2032757
Here is the link to upgrade from vCenter 5.0 to 5.1:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2032283
I strongly recommend you use the VMware Interoperability Guide, in case you have older ESXi hosts (i.e. 3.5) that will no longer be managed when you move to vCenter 5.1.
Hope that helps.

World updates, ext4 and Reiser4, and offline installation Questions

I am deciding between Sabayon Linux and Arch Linux, and on the Sabayon forums the term "world update" is all over the place. I am still not certain what exactly that term means, but I always see it used in conjunction with reconfigurations and recompiling the operating system. On the other hand, a search for "world update" on the Arch forums yields absolutely nothing. Why is this? Is there any way or need to configure Arch Linux for a specific hardware setup?
This Wiki: http://en.wikipedia.org/wiki/Comparison … tributions says that Arch Linux supports Reiser4, but that its support of ext4 is unknown/who knows. In what way does Arch support either of these? If I installed Arch onto a partition that has the Reiser4 file system, would Reiser4's full abilities be put to use? I realize both Reiser4 and ext4 are experimental, so that might limit their current abilities, but I am mainly interested in what limitations there might be in using Arch and Reiser4 (or ext4) together.
How easy is it to download a package or open source on another computer and then install that package or open source onto Arch on a computer that does not have Internet access? I do want the package manager to know about the installation so that the program can easily be removed. Would it be very difficult to update programs by downloading the files elsewhere and installing them on a different computer? Using dial-up is like trying to stand on a frictionless surface.
Thanks

Thank you. I am rather certain that Arch has won the battle over Sabayon simply because it updates and runs out of the box much better than Sabayon.
According to http://en.wikipedia.org/wiki/Comparison_of_file_systems, ext4 has allocate-on-flush and extent features. Those are both things that I would really like. Reiser4 has these and several other features that I would like, but I certainly am not capable of patching Arch to work with Reiser4. According to this same website, ext4 and ext3 have the same maximum file size limit. The only gain in size is ext4's maximum volume size limit, which is certainly much more than ext3's. Either way though, I am not worried about maximum file or volume limits. I simply would like the features that ext4 contains that ext3 does not contain.
Thank you lucke for your help. With that information I doubt I will try ext4 until it is considered stable. That leaves me with ext3 or ReiserFS, and I think ReiserFS wins because of its tailpacking and block suballocation features.
Also, I am new to compiling, so if I compile a program on Arch, is the program registered with the package manager so I can easily remove it? Is the program updated through the package manager?

Solaris Cluster and VMware Disk and SCSI Sharing Questions

Hello folks,
Does Solaris Clustering support the following?
Oracle Solaris 11 Cluster support shared disk using VMware 5.1 RDM?
Oracle Solaris 11 Cluster using VMware SCSI Bus Sharing? (although VMware doesn’t support this)

Networking And Target display Question.

If I have my 2011 iMac all set up and running as a slave using the ethernet port can I then use my iMac's display with the other TB compatible Mac using target display mode.
This would be for the Vienna Ensemble Pro 5 where the iMac would be used for the sample libraries.

Hi Phillip,
No idea & can't test, but it should be safe to try.

Some installation questions concerning AS and 8i

I will be installing 8i Enterprise Edition so that I can work with 9i AS. I have read through most of the Installation Guide for Oracle 8i - Enterprise Edition Release 3 (8.1.7) for Windows NT. I have some questions that didnt seem to be addressed in the documentation.
How to access Web Site component?
Appendix A, 'Individual Components Available for Installation,' indicates that the Oracle Enterprise Manager Web Site component is not included in either the Typical or Minimal installations of Oracle 8i Enterprise Edition. Is it available through a custom installation, or how do I access this component?
Advanced Security questions:
That same appendix also makes it clear that one of the primary differences between the Typical and Minimal installations is all of the Advanced Security features (encryption and integrity support; authentication support; and so on). It seems that I will need the Advanced Security component, because I will be configuring a database that stores usernames and passwords. However, I will be working with Oracle Portal. Can security features be configured just through Portal and 9i Application Server, or do I need to use Advanced Security instead, or in addition to, Portal and AS?
From what I understand, Advanced Security works with SSL (Secure Socket Layers). Does this affect visitors' ability to access a Web application anonymously before login (doesnt interaction with an application in SSL require online exchange between computers of authenticated, encrypted digital certificates? I hope this question makes sense; I'm new to the topic.) Is there a short answer to this question?
Application Server instead of Oracle HTTP server:
I also saw in Appendix A that the Oracle HTTP server powered by Apache is included with both the Typical and Minimal installations. It's also bundled as a "Web listener" with the Oracle Enterprise Manager Web Site.
However, I will be installing 9i Application Server instead to work with the 8i database. Will this cause any conflicts? I'm just wondering if the Oracle HTTP server component can be excluded from the beginning, without doing a custom install. I did see on pg. 3-6 of the Installation Guide (under 'Oracle Enterprise Manager Web Browser Requirements') that Oracle Enterprise Web Site does support the Oracle Internet Application Server.
Also, I understand from the section on 'Mandatory Individual Component Requirements' that Advanced Security "requires preinstallation of an LDAP directory such as Oracle Internet Directory (provided on the component CD-ROM)." It refers me to the Oracle Advanced Security Administrator's Guide for further information.
Oracle Internet Directory:
However, I haven't been able to access the Security Administrator documentation yet for installation procedures since I haven't been able to successfully download 8i Enterprise Edition (with all of the supporting documentation) yet.
I looked at the online 8i documentation at http://technet.oracle.com/docs/products/oracle8i/doc_index.htm but did not see any reference to the Advanced Security Administrators Guide.
As for Oracle Internet Directory itself, I did just find the Oracle Internet Directory Administrator's Guide on the oracle8i/doc_index.htm page mentioned above - so that should help.
I also looked at the Oracle Internet Directory download page to see if links to documentation might be provided there, but saw that "Oracle Internet Directory Release 2.1.1.0 is delivered as part of Oracle8i Release 3" which leads me back to the 8i Enterprise Edition page where Ive been experiencing download difficulties. So far as I know, theres no evaluation-version CDs available for this software, though there are evaluation CDs available for 9i AS.

@op - the tip that urfaust posted is contained in the beginners_guide wiki article. You should not attempt installing arch without reading this guide. If you have two computers, you can install arch on one while browsing to the guide on the 2nd.

KDE 4.1 and installation questions.

Hi,
I want to move up to Arch from Mint and PCLOS but the installation routine has me a little apprehensive. I always read reviews of Arch Linux and sometimes the reviewers give the impression that the installation is not for newbies. I am not a newbie anymore but I don't have a lot of time to tinker or learn - just the facts.
So, Is the installation process challenging for the averagely intelligent person with some Linux experience with the easier distros like Mint and PCLOS ? Also, how is KDE 4.1 working out on Arch ? I would definitely like to try it if it is up to snuff now. I read that 4.0 release was pretty bad.
Thanks,
B.

The documentation for installing Arch is pretty good. I found that I did have to hunt around a bit at times to get everything set up, but it is all there if you look. You can be up and running quite quickly if you know what you're doing. If you don't, you might be in for a long afternoon.
The main difference between an Arch installation and say, PCLOS, is that with PCLOS, the install is always going to end up with a KDE desktop, KDM, sound, etc, so they can automate most of the process for you. Arch is completely ala carte, so to get a KDE workstation, you have to do the base install, add a user and configure them, install X, add support for your graphics card, configure support for sound, install HAL, install KDE, install KDE applications, set up and configure networking, and then install KDM (and I'm sure I'm leaving some stuff out).
Again, there is documentation for doing all of the above, BUT if you haven't done it before and you do things out of order, or can't figure out one of the steps, you can get stuck for a very long time.
What was your reason for wanting to ditch PCLOS in the first place? Just something different or did you have something in mind?

I upgraded the OS on my iMac to Lion from the App store; and after installation, it restarted and now the operating system won't start up.... it keeps displaying the apple/folder with a question mark and a circle with a line through it! Please help!

Try starting up with your Snow Leopard DVD and see if the disk can be repaired. Once you are at the installer screen go to the Utilities Menu and choose Disk Utility and choose repair disk. You might also want to try Diskwarrior.
Hope this helps.

HT4623 I am using my iPod to ask this question, but I can't get wifi on my iPad mini. It showed the network, and says it is connecting, but it won't complete. Thanks in advance

My iPad mini isn't connecting to wifi, and I need help. I have tried forgetting the network and retyping the password, turning off wifi and waiting, and just giving the network time to try and load. None of the worked. I need answers as soon as possible
Thanks in advance

1. Turn off router for 30 seconds and on again
2. Settings>General>Reset>Reset Network Settings

Very basic questions, network and drive

I am a newbie to macs. So please excuse me if these sound stupid. How do I figure....
a. Which drive do I have. Superdrive or the normal drive
b. What kindof network is being used on the macbook
I am using a wireless network with Airport extreme. I know that part. I mean how do I figure if its an 802.11G or N
c. How do I figure what the network speed is.
d. What speed should I expect for both 802.11G and 802.11n
I have the 2.16ghz white macbook....
http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?nnmm=br owse&mco=5D8C6B1&node=home/macbook/macbook

1. you bought the 2.16GHz. You have a super drive
2. You really can't tell unless you know the wireless router being used you can "guess by speed"
3. Open up network utility in your utilities folder (in your Application folder) Select en1 for your wireless network and see what speed it tells you it's using. If it's 54, it's g, 11, it's b, faster than 54, probably n.
4. g= 54Mb, n is faster, I only ever see 5x faster than n. I never see an actual number set to it. The N specification is still "draft" and not fully developed yet.
Enjoy your MacBook.
Additionally you can download widgets like iStat pro that will give upload/download speed of the network in real time.

10.4.11, VMware Fusion and Windows XP (Home Edition) works just fine

OK, so I'm through the installation of VMware Fusion and Windows XP (Home Edition) and I have to say that it was pretty much point and click as advertised. All network services seem to be working and I'm running both OS side-by-side with out a hitch.
Haven't put the system through any rigorous test yet, like VPN, network printing or rending large graphic files, but the installation, setup and normal operation went smoothly taking about an hour in total.
Machine: MacBook Pro, 1.8Ghz with 1G of RAM memory and dual monitors.
Host OS: MacOS 10.4.11

I now have installed XP Pro into a Boot Camp Partition. Basically point and shoot. Then while booted in XP I used PC Mover to migrate my old PC to the Boot Camp partition. With the exception of one program and my virus and firewall programs all went well, almost point and shoot. Then I installed VMWares Fusion and used my Boot Camp partition as the source. If you follow instructions from VMWare things work relatively problem free.
After posting questions on VMwares site about processing video and compiling DVDs in Windows using Fusion I decided that such processor intensive requirements are best handled in the Boot Camp (native) mode.
The biggest problem I have encountered is that Microsoft Office constantly asks to be reactivated when switching between Boot Camp startup and Fusion. No solution I know of, except not to use Office in Boot Camp Mode. Secondly XP Pro required a re-authorization from Microsoft so I could run it in both Boot Camp and Fusion modes. Obtaining the authorization (activation code) from Microsoft was not a problem.

How can I use PowerShell to Remove "Ghost" (Old Hidden) VMware Network Adapters in Windows 7?

We recently upgrade the virtual hardware of some of our VMware VM's running Windows 7. One side-effect is that in Windows on these machines, an instance of the NIC from the previous version of virtual hardware remains, as a hidden
device. This can be easily found manually on a machine by enabling Device manager to show hidden devices (registry and a menu option - View...Show Hidden Devices). You can then just right-click on the device in question and uninstall.
The problem here, like in so many other tasks, is that you may have multiple instances, on multiple machines. We had just that, and in scouring the internet for a PowerShell only script to resolve the issue, I could not find one. Therefore, I've written
my own.
This exact script is only seeking out VMware "VMXNET3" nic cards, but could be easily adapted to find Ghost NIC's for a different vendor using my example. There are also some commented lines left in to aid you as an example of how you can
test the various queries in your own environment, on a test machine, before a full-blown deployment.
NOTE: Please try this out (at your own risk - I am not responsible for how this works out for you), and please vote for my answer to this dilemma if this helped you. I'd appreciate it after all of the sweat the script took to crank out.
Thanks!
P.S. This script, of course, requires that Powershell is installed and enabled on the target computer. It then must be run as System - In our environment it is being remotely pushed through a software delivery systems, which runs this scrpt
as system.

Hello Octavio,
I'm having similar issues with azure VMs (windows server 2008 and 2012). I noticed that the name of the network adapter changes every time the servers are turned off and then on.
For example every time I perform that action on each VM, the network adapter became to "Microsoft Hyper-V Network Adapter #3" (and then #4, #5, etc).
I found in to many forums that to resolve that is needed to remove Hidden (Ghost) Network Adapters and most of the people is doing that manually from the device manager (right click on the hidden network adapter and select uninstall).
Then I found this script created by you and made some changes to find Description -like "Microsoft Hyper-V Network*".
It seems to find the adapters and also remove them (based on the script results). But if I go to the device manager after restarting the server, all hidden (ghost) adapters are still there (for example Microsoft Hyper-V Network Adapter
#2, Microsoft Hyper-V Network Adapter #3, Microsoft Hyper-V Network Adapter #4, Microsoft Hyper-V Network Adapter #n).
The only thing I noticed after running the script is that, in the Control Panel -> Network and Sharing Center, the name of the adapter has no # (Now is shown as “Ethernet” and before as “Ethernet #”)
This is my script, could you please take a look and tell me if there is something wrong o missing?

"Business Network" and "Without a Domain" -- Consequences?

In Windows 7 SP1, during installation (or later in "Control Panel\System and Security\System," under "Computer name, domain and Workgroup settings," click "Change Settings," than "Network ID") you get the following
choice:
This Computer Is Part of a Business Network; I Use It to Connect to Other Computers at Work.
This Computer Is a Home Computer; It is Not Part of a Business Network.
If you choose the former, you get the further choice:
My Company Uses a Network With a Domain
My Company Uses a Network Without a Domain
"Home Computer" is straightforward and allows you to set up a Workgroup or a Homegroup. "Business Network" followed by "Without a Domain" appears to behave the same way but is **reputed** to prevent homegroups (which is
desirable) and in general to provide a higher level of networking security. Is either of these assertions actually true?
Suppose you choose "Business Network," then "Without a Domain," or alternatively, you choose Home Computer," and in either case you continue through the wizard to the end. You have to restart, so you assume some significant
changes have been made. Yet if you then go back through the Control Panel procedure given above, you find that "Business Network" and "With a Domain" are pre-selected, causing you to wonder if these changes persist.
So my main quandary is this: Do these choices produce persistent effects that can be seen in one of the Policy Editors (or even the Registry Editor)? If so, how do you find, and if necessary adjust, them?
Similar questions have been asked at http://answers.microsoft.com/en-us/windows/forum/windows_7-security/difference-between-home-network-and-business/85597e92-2b38-4d2f-b7b3-6f45f3c750d5?tm=1390436195902, at http://answers.microsoft.com/en-us/windows/forum/windows_7-security/home-vs-business-network-choice-can-you-get-back/74a872bf-18d4-437b-99b2-ded5fa60df4e?tm=1418982314037

Hi,
This choice could affect many registry entries. It's hard to figure out every entry.
For example, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\History
there is Machine Domain entry stand the current domain name.
When you choose any one of them, after restart, registry entry will adjust this new settings.
In addition, Business network without domain and home network is different. since the domain network have some security restriction for all domain network no matter if you are in doamin or out of domain.

FIM Service and Portal Installation Ends Prematurely

Hello All,
I'm in the process of setting up a new production FIM 2010 R2 server. I have already installed the FIM synchronization service and I was able to install this successfully.
I have already installed SharePoint services (WSS 3.0) and configured it for FIM. But when I try to install the FIM Service and Portal.
I keep getting and error that says " FIM Service and Portal Installation Ends Prematurely" with no other details. If anybody has any advice please let me know.
I have already installed everything on a stand alone box in a dev environment and it all works correctly however I am unable to now install in a production environment

Cameron is right - you should consider FIMService account nearly as normal AD account for user*
An installer account should be admin on the box, where you are installing FIMService and he should be sysadmin on SQL during installation of FIMService. An installer account should be other than FIMService account itself.
*FIMService account:
Lock down the Service Account
The service account should not be used by any other services or users. The account must not be used to logon interactively and requires no access to any additional resources beyond those granted during setup. The service account is used to provide the security
context for the MIIS service as it accesses resources on the MIIS server and the associated database. It also provides the security context for the execution of any rules extensions.
Lock down the service account to ensure no malicious user is able to sign in using its credentials and gain access to MIIS data. Configure Group Policies to lock down the account and restrict access to this account. Since the MIIS service only needs the account
to run as a service, restrict the account as follows:
Deny logon as a batch job.
Deny logon locally.
Deny logon through Terminal Services.
Deny access to this computer from the network.

Does ACI support a VXLAN Tunnel between Leaf(Leaves) and VMware-vDS, and MS-vSwtich?

Hi Experts,
I have a quick question about Normalized Forwarding of ACI Fabric.
Does ACI support a VXLAN Tunnel between Leaf(Leaves) and VMware-vDS, and MS-vSwtich? Otherwise any plan to provide that function in the future?
If there is no function and plan How is Normalized Forwarding possible with VXLAN headers that are generated by each Hypervisor? Of course I know it's possible for a VM on ESXi to communicate with another VMs on Hper-V without VXLAN but I just focus on Normalized Forwarding between Multi-Hypervisor.
Or If AVSs are implemented on ESXi and Hyper-V repectively, is it possible to make a VXLAN Tunnel between Leaf(Leaves) and AVSs on ESXi and Hyper-V? And what is a example of that usage?
Thanks in advance.
Paul

Hi Paul,
As I understand, ACI Leaf to the VMware-vDS is still vlan so no tunnel for VXLAN. When we integrate Vcenter with the ACI, We define the vlan range for the traffic from VM-ware-vDS to map EPG to a VMware ESXi port group.
For the MS-vSwitch, As It support OpFlex agent could act as VTEP but not part of the fabric. But I am not sure about this.
As AVS is part of the fabric so It will act as a VTEP (VXLAN Tunnel between Leaf(Leaves) and AVSs)
But what is the benefit are you looking? Traffic normalization is still there because Traffic within the fabric is encapsulated as VXLAN. External VLAN/VXLAN/NVGRE tags are mapped at ingress to an internal VXLAN tag.
Note:the VLAN ID has local significance for the leaf node

Anser

Inherited Linksys Voice over IP and data installation.

I have just inherited a brand new linksys, voice over ip data installation. It has roughly 25 telephones and the same number of computers with new WMP300N network cards and SPA941 IP telephones. The company remodeled an old construction with 100% masonry wall (brick and/or concrete). The remodeling included the 100% wireless data and telephone installation. Now that the remodeling is finished and work has started, the network saturates as soon as there are a few users. The computers are all using LinkSys WMP300N cards and the telephones are all LinkSys SPA941. They installed approx 15 wifi repeaters for telephones and 10 for datos. They installed two separate but identical AP's, one for Data and the other for Voice but both on a 192.168.1/24 subnet.(Zonet ZSR1124WE) The folks who installed this didn't, for some reason, use LinkSys AP's and repeaters but used Zonet ZSR1124WE for all.
My questions are:
1. Wouldn't using the same subnet be the same and using the same
wire that that would allow voice/telephones to saturate and
slow down the data even though the AP's are separate?
2. Wouldn't channel interference between the aprox 25
repeaters be common?
3. If I were to remove all their equipment (APs and repeaters.)
an install 2 LynkSys AP's in the center of the offices
where there is an open patio with a watt or better amplifier
(not illegal here, not in the U.S.) output and a high gain
antenna on each of the two and using separate networks.
172.16.1/24 for datos and leave 192.168.1/24 for telephones
have a chance at success and if so could you estimate
how much of a change and recommend equipment and/or other
critical or semi-critical points that I have missed?
Thanks,
ed
P.S. I have my doubts that this is even possible but it would be cool, if it only worked

Umm.. you left out quite a bit of information:
How are the wired phones connected to the wireless network?
What channels do the APs use and how are they connected in between each other (and other wired data equipment)?
What kind of network is it? B, G, N?
How many WLAN channels are used? One per AP and all repeaters use the channel of the AP they repeat for?
As far as the subnet goes, the current setup shouldn't be a problem - I figure the problems are more likely to come from the wireless than the wired part of your network. Considering that you're basically halfing the throughput with each repeater (assuming the same channel which is likely since there are only 3 that do not interfere unless you have an A network) - the sheer number of repeaters is most likely to be blamed for the poor performance. Traditional WLAN networks generally use a wired backbone, plus you'd have a single net and use one of the three distinct channels in order to minimize interference.
Increasing the output of the main antenna is also only half of the problem... if you can reach clients that are farther away, those clients will also need the appropriate power output to reach the base again - and those wireless cards are limited in that way.
There are two essential pieces to tracking down a problem with your VoIP equipment:
The configuration of every device involved
SIP protocol traces
And don't forget: there's no such thing as giving too much information when describing a problem.
