Size of minimum LUN for ESXI 5.5

• Size of minimum partition for recovery

  Hi, I tried to install windows using HP recovery DVD (4 of them) on my 128 GB ssd, I got the error message saying that the minimum partition size is 140 GB and I can not continue, is it possible to get around this?

  The capacity of the destination disk must be equal or larger space of original disc - unused space is not included. For example, if your current installation is on a hard drive of 320, but but is only using 50 GB of space on the hard drive it can be cloned to a 128ssd.

• Custom partition sizes and memory system for ESXi 4.1

  With ESX 4.0, I would customize my partitions during the installation (see below). With ESXi 4.1 GUI there is no option to customize the scores.

  Now is the best practice to take default values? If not, what are the ESXi 4.1 recommended sizes of partition and how do you custtomize them?

  What memory system. In the past, I would rise to 800MB (1/2 of the swap partition). ESXi 4.1 design requires no it more? I can't change that vcenter as I could before.

  Who wish to understand best practice in this version build information.

  root (/) 5120

  swap 1600

  var 4096

  Home 2048

  opt 2048

  tmp 2048

  You cannot change the size of the partition. If this is embedded (installed to USB) then ESXi will use total 1 GB. In the case of installation (installation on a hard drive) ESXi will use 1 GB and create a separate partition from scratch 4 GB.

• Home minimum memory for HA?

  The minimum memory for ESXi should be 2 GB of RAM, but I wonder if it's enough for the performance of the HA Agent? He failed on the two test ESXi with 2 GB of RAM to configure HA and something error messages made me suspect lack of RAM. After you have added up to 2.5 GB of memory through HA.

  So my first question is: all amount of RAM minimum on a host for HA to work?

  On the same cluster with these two small ESXi servers, I noticed that the size of the slot was about expected, something like 256 Mhz and 360 MB of RAM. HA setting = tolerate 1 node and small running virtual machine only. Which was quite strange for me was the the advanced Runtime Info reported only 1 single location across the cluster and when making a HA test with power off of a host, the virtual machine has not failed to wire and HA ' not enough resources for failover VM"or similar. Why this might be happening? HA expects more RAM available?

  HA requires 2 300 MB memory allow. If you have less than this amount, you will get an error when trying to activate HA.

• Size of data store for just an OS LUN?

  This seems to be a silly question for me, but the alarm is shake me up.

  If I want to create a data store that is just a LUN for an OS only, what size does?

  For example, in the construction of a Windows Server 2008 R2 machine, I created a LUN on the SAN for just the OS and set it to 50GB.  Then, in vCenter, I add the storage to the ESXi hosts as a data store (lets call it OSLUN).  Then I create a virtual computer and use OSLUN as the hard drive, 40 GB provisioning (think that is all I need).  Now, because I chose 8 GB of RAM, the total of the VMDK ends up being 48Go.  vCenter launches an alert to 'Use of data to drive store' saying 49,75 GB it remains only 1.24 GB.

  It makes any sense to me, except the alarm that makes me think I'm somehow running out of space to store data... should I just ignore this alarm?  I do not see how I'd go on the space allocated for the LUN of the OS.  :\

  Unless you were to store these things on different sets of pins he won't have too much difference. Keep your environment as simple as long as you can. Adding to the complexity when it solves a specific problem not only because you can.

• Minimum hardware requirements for ESXi 5

  Hello

  I am a newbie of virtualization and ESXi so please help me on these issues:

  I intend to host 1 Windows 2008 Server and 1 Pfsense on the same host with ESXi. The two servers to serve a small number of users (less than 10). The Win2k8 runs just small .NET application and the just Pfsense will act as a router/gateway for web portal (without VPN, nothing complicated here).

  I checked the minimum requirements for VMWare ESXi here (KB VMware: minimum system requirements for installing ESX/ESXi) but still uncertain before buying new equipment to run ESXi because the specifications said ESXi only works on 64-bit x 86 CPU.

  I'm looking at this PC:

  CPU: Processor Intel® Celeron® 1037U (2 MB Cache, 1.80 GHz)

  RAM: 8G RAM Support memory DDR3 2 G / 4G / 8G / 16G, DDR3 1333 / 1600 MHz

  Storage: 64G SSD

  
  

  ESXi will install OK on this system?

  
  

  Thank you
  

  Hello

  Intel http://ark.intel.com/products/71995/Intel-Celeron-Processor-1037U-2M-Cache-1_80-GHz CPU specs this should work in general, but can cause performance problems as this Celeron has only 2 hearts.

  Another thing to consider is the RAM, ESXi 5.5 OS takes about 4 GB of RAM on the 8 GB leaving you 4 GB for VMs Windows 2008 with less than 4 GB wil be quite slow and sooner or later begin to swap to disk.

  Also the motherboard used is something check with HCL as at the storage controller and connect it on Board should be compatible.

  The road easier to go is to get the material at the level of the server that is listed in the HCL, you can find systems awarded new/used being fully compatible. It would be much more reliable than the construction of a whitebox on office equipment system.

• Size of the LUN Max size minimum and maximum RDM?

  The Maximums on 4.1 Configuration seems to have been a change in the size of the LUN max, of the strange 2 TB - 512 bytes to just 2 TB. Can anyone confirm that it is correct in 4.1? As I understand it in 4.0, if you got your logic unit number created to exactly 2 TB, you have lost about 500 GB of space (?).

  It would be interesting to know if it is "fixed" in 4.1 and if only the use of 4.1 hosts then 2 TB LUNS could be created?

  In addition, the maximum size of RDM always seems to be 2 TB - 512 bytes in 4.1. What is the reason for this kind of limit? If the guest operating system can accept more large drives of 2 TB, which need not enough?

  ricnob wrote:

  Even on the store of NFS, the maximum size of virtual disk to a virtual machine will be 2 TB - 512 bytes?

  Yes, there is a maximum specified for the virtual machine.

  Would a connection iSCSI comments launched a LUN liked work of 2 TB (if the guest operating system can handle)?

  Yes, it's a way to work around the limitation of current 2 TB - 512 bytes.

  The information about this change in the passage of Q & A at the end of TA7121 - ' next generation VM Storage Solutions with API for integration (VAAI) Array vStorage "was held in San Francisco just a couple of weeks.

  Interesting. Did you get any sense if this possible change should come an update for 4.0 - 4.1 or may appear in a future version, 4.5 or 5.0?

  I will attend at Vmworld in Copenhagen in October, so maybe I should visit this session.

  You know, I don't really have a strong impression be it on this issue.  My stomach seems to tell me that it will be in the next version of main product.  If I remember correctly, one of the presenters of the session was one of the engineers who worked initially make VMFS.  This session was really good, so I recommend anyway.

• Good 'size' of 2 TB LUN for ESX

  I have the need (on occasion) to provide a virtual machine with a 2 to VMDK.  To do this, I need of course a 2 TB LUNS with a VMFS on that.

  My question is, what it the right size in GB I should introduce to ESX to ensure that ESX (a) we'll see OK and (b) I can only close to 2 TB VMDK possible?

  We have managed to get a unit logic 2048 GB (real 2 TB) visible to ESX number, but had to format it to the command line that the VI Client didn't like it.

  Any suggestion is appreciated.

  See you soon,.

  Doug.

  The maximum size of the LUN is actually 2 TB - 512 bytes - this is due to a limitation of 32-bit and fresh address generals for VMFS accounting.

  You will definitely want to read this article.

  It applies to vSphere, but good information, unless you want to mess with your storage during a space upgrade.

• PowerCLI reports wrong of the LUN size when perennial reservations are met * and * size of the LUN is changed.

  My question is: is this expected behavior?

  In short, the situation is this: we have a cluster running ESXi 5.5.0 build 1746018. Two guests Windows Server R2 2012 are running a SQL Server Cluster (MSCS), making use of RDM with a physical SCSI emulation. Which requires LUNS of perennial reservations activated. All is well until the customer decides to expand two of the LUNS. PowerCLI continues to account for the original size of those LUNs, which breaks our reports.

  Logically, it makes sense, but it still seems a bit of an ejection. Has anyone seen elsewhere this behavior and you have found ways around it?

  See you soon!

  You didn't say how to retrieve the size of the LUN.

  If not through esxcli, not the following returns the correct size (change the hostname ESXi and LUN canonicalname)?

  $esxcli = get-EsxCli - VMHost MyEsx

  $esxcli.storage.core.device.list ('naa.60050768123455af1800009876000023')

• Help Setup RAID SATA for ESXi 4.1

  Hello

  It is the first time that you try to use vmware.  Any help is greatly appreciate!

  I just built a server around the Intel s5500hcvr mother. I have 6 SATA HDD I want to set up in a RAID. The integrated RAID controller seems to be very limited and does not seem to be supported by ESXi 4.1 (when I run ESXi 4.1 installation and it asks for a location for installation, all my discs are individually listed instead of virtual drives that I created with the RAID controller)

  My questions:

  (1) what is the suggested configuration of HDD (RAID levels / number of berries) for ESXi 4.1?  Can I create 1 RAID 10 array and set everything up to that?  or take one of my disks and install esxi 4.1 on it and then create a RAID with the rest of my discs and use it to store data?

  (2) anyone can provide links to some SATA RAID controllers that are known to work with ESXi 4.1 (and is the supposed to recognize virtual readers created by the RAID controller setup ESXi 4.1)

  Your motherboard has a RAID controller software which, as you have discovered, is completely not taken in charge by ESX/ESXi... You will need to get a RAID controller that is on the HCL for SAS and SATA hard drives (not one with battery backup write cache) so you can use any type of RAID configuration.

  My preference for Internal RAID configurations (on the host) are two drives mirrored for ESX/ESXi to reside (preferably being SAS 10 k or 15 k RPM, 73 GB or 146 GB in size) and then another table for the data store. You'll want to keep the data slot store table 2 TB-512 b size in order to present to ESX/ESXi as a LUN. Or you will need to get a RAID card this split of the support to the top of the table in the smaller of the virtual drives that can be presented for ESX/ESXi and LUNS.

  Search for controllers using the LSI MegaRAID chip as a good first lap. Some Adaptec cards should work, but I've seen people post questions on those recent (more recent than in the past). MANY manufacturers rebrand/efficiency the LSI MegaRAID Controllers server, such as the Dell PERC 6 series cards.

  For the use of 4 disks SATA, RAID 10 (on a BBWC, fully supported, controller) will give you the best performance. It will compare with SAS drives however. IF you do not plan on any virtual machine running with anything beyond light IOPS / s then you should be ok (or with very light loads)... If this is going to be a production server, then get the SAS drives all around.

• Take the minimum value for table data

  I'm storing test data in a table, with the hope that I can output the minimum value of the data. So far, I have used the table of max/min but can't make it work how I want. The test runs continuously in a loop of the holder. I get the minimum values in the table, but I would like to change the number of samples that the table contains, before it generates a minimum. The other option is that I run the test for a period of time (e.g. 3 seconds) and the table stores the data for this time then output 1 minimum value for the entire period.

  My current configuration VI is attached.

  Very appreciated

  Chris

  The size of the array in your VI is determined by the number of samples that you collect in your DAQ assistant, who is now 100 samples.  Never more, never less.

  How many samples do you want before you determine the minimum?

  Maybe what you really want to do is to build the table in the while loop and store it in a shift register, and when the loop has repeated enough times, then you take the minimum of built table.

• Size of minimum score HD Win7?

  I'm upgrading from Vista Home Premium to Win7 Home Premium.  I have a 500 GB HD and we'll add a second 1 TB HD.  I'd like to partition the 500 GB for the OS and the photos, what is the size of minimum/optimum partition for just the OS Win7 Home Premium?

  Minimum recommended - 20 GB for 64 - bit, 16 GB for 32-bit.

  At least real - about 12 GB

  I wouldn't not less then 20 GB. 25GB would be a good size.

• Service profile of the CISCO UCS for ESXi

  Do you need multiple boot LUN on the storage array for each host that you want to apply the service profile to? I'm just confused, let's say I have 12 blades that I want to designate as boot SAN for ESXi, y aura-t 12 profiles of separate service for each of them, and will need me 12 different LUNS on our storage? I am new to this and I just want to make it as clean as possible! Any help is appreciated.

  Hi Justin,

  You can have the same LUN ID for multiple service profiles, as well as the same target ID. However, your initiators will be different and you will need to configure the zoning on your switch upstream if you use the end host mode.

  Here is a good guide, review the basics and how to put in place.

• How do I configure Openfiler for ESXi 5.0 (on which has been installed in the workstation).

  9.0 pre-installed VMware I installed in my laptop. I created a 5.0 as a VM ESXi in workstation. And I installed vSphere client 5.0 in my laptop. And I am able to access ESXi from my laptop through the vSphere client.

  Now, I created a VM with Windows 2008 R2 on top of ESXi. I installed vCenter 5.0 in Windows 2008 R2 Machine. I have just to connect to vCenter using vSphere client (which has been installed in my laptop) and added ESXi as host in the inventory.

  Now, I created a VM with Openfiler. Everything is fine. I want to use this Openfiler as a storage array, and I want the SAN with ESXi and Openfiler configuration.

  I think I need to create a VMkernel port group and attach that Openfiler VM who. And if I want to access the Openfiler web interface, do I need to have internet access? We can access the Openfiler Web interface without having access to the internet?

  Can someone let me know how to connect this Openfiler as a storage Bay for ESXi and configure a San.

  Openfiler does not need Internet access and you do not require an additional VMkernel port for access.  If it's production, you share the management and traffic on NIC iSCSI physical separate and thus vmkernel ports.  In this case, it is not necessary.  Did you do the initial installation of Openfiler to create a LUN for the ESXi host access?
