• Need help with the data storage store, local array and network connections

  Need help with my ESXi 4.1 installation

  My hardware:

  I built a server with an Asus P6T whitebox, i7 920, 12 Gig RAM, NIC, Intel Pro1000 PT Quad, 3ware 9650SE-12ML with 8 1.5 TB SATA green in a raid 6 array gives me about 8 + TB with a spare drive all housed within a NORCO RPC-4220 4U Rackmount Server chassis.  I also have a 500 GB SATA drive which will hold the ESXi and virtual machines.

  The network includes a firewall, Netgear Prosafe FVS336G, GS724Tv of Netgear ProSafe 24 port Gigabit Managed Switch on a dhcp cable modem internet service provider.

  I also have 2 old NetGear SC101T NAS disks (4to) I want to connect to the system how some - at a later date have... data on them and want to transfer to the new storage array. I always looking into the question of whether they will work with ESXi 4.1, or I might have to only access it through Windows XP.

  My Situation:

  I have already installed ESXi 4.1 and vsphere client with no problems and it is connected to a dhcp cable internet service.  I've set up host via a dynamic DNS service name give me a static hostname on the internet.  I installed three machines to virtual OS successfully at the moment and now want to first start by creating a multimedia storage server which will use some of this new 8 TB array, then separate data storage for use with a web server small overhead storage and a backup.  It is a domestic installation.

  Help with the data store and network:

  I was doing some reading, because I'm new to this, and it looks like I'll probably want to set up my table via ESXi as a nfs disk format.  Now, the data store is usually in another physical box from what I understand, but I put my readers and ESXi all in the same box.  I'm not sure that the best way to put in place with grouped network cards, but I want to make this work.

  I understand that in ESXi 4.1 using iSCSi LUN must be less than 2 TB, but nfs - I should be able to add a bigger partition then 2 TB (for my multimedia) in nfs, right? or should I still add it separately as a separate 2 TB drives and then extend them to get the biggest space.

  Any suggestions or direct resources showing examples on how to actually add some parts of the table as data warehouses separate nfs.  I know that to go to the configuration tab, and then select Add to storage, and then select nfs. I have not my picture, but it's here that I don't know what to do because ESXi 4.1 system already has an address, should I put the same thing to the new data store array also (will it work?), and what should I use for the name of the folder and the store of data... just do something to the top.  I thought to later install Openfiler (for a multimedia storage using this table server) as a virtual machine, use the table with esxi so that I can access the same storage space with widows and linux-based systems.

  I also know I have to find a way to better use my quad nic card... put in place of virtual switches, grouping, etc HELP?

  Any direction, assistance, similar facilities to sample, suggestions or resources that would help would be great. I did a lot of hunting, but still a little confused on how to best to put in place.

  You must think of VMDK files of large databases with records of random size guest go read some data (a DLL or an INI file), maybe write some data back, then go read other data. Some files are tiny, but certain DLLs are several megabytes. It's random i/o all and heavy on the search time. IO Opsys is small random operations that are often sequential (go read data, write data, go read other data,...) so that deadlines are critical to the overall performance. That's why people say OPS are / s of reference and forget the MBs flow. The only time where you bulk transfers are when you read media (ISO files).

  Well, now forget all this. Actually the disk activity will depend on the specific applications (database? mail server? machines compiler?), but the above is true for boots, and whenever applications are idle. You should see the profile to know.

  RAID 10 is faster (and often more reliable) than RAID 5 or RAID-6 except in certain specific cases. In General RAID 10 is ideal for many random writes, since the calculation of parity for RAID-5 and - 6 adds to the overall latency between command and response - latency is cumulative if a little slow here and a little slow it adds up to a lot of overall slow synchronous especially with e/s on a network. OTOH RAID-5 and -6 can produce faster readings due to the number of heads, so you can use it for virtual machines that transfer bulk. Test. You may find that you need several different types subdashboards for best results.

  You said 3ware, they have some good grades on their site, but don't believe it. With my 9650 that I found myself with only a couple of their recommendations-, I put the (simple) table for allocation size 256 k, nr_requests at 2 x the queue_depth and use the planner date limit. I had the habit for the Ext4 file system formatted with stride and stripe-width synced to the table and used the options large_files with fewer inodes (do not use the huge_files option unless you plan to have single VMDK files in the terabyte range). Use a cache of great reading in advance.

  Virtual machines use VMDK files in all cases except raw iSCSI LUN that they treat native disks. VMDK is easier to manage - you can make a backup by copying the file, you can move it to a PC and load it into another flavour of VMware, etc. There could be some features iSCSI to your San as a transparent migration but nothing for me. NFS has less chatter of Protocol if latency lower times to complete an operation. NFS is good to read and write a block of data, that's all it boils down to.

  UPS is good, but it won't help if something inside the machine explodes (UPS does nothing if the PC power supply goes down). If the RAID card has an option for a battery backup module, so it can contain some writings in memory and may end up the disk i/o after replacing the power supply. 3ware also limits the types of caching available if help is not installed, and you get just the right numbers with the module.

• Performance of the LOD approach for network analisys

  Hi all,
  
  I opened the new thread to talk about the performance of the LOD approach for the analysis of network using Java APIs as the continuity of this thread:
  Partitioning of the network using the API of LOD
  
  I remember you that:
  -I'm using Oracle 11 g R2;
  -My Network 7.817.372 links and 6.662.079 nodes (network);
  -The table of links LINK_LEVEL is set to NULL;
  -J' partitioned network with these procedure:
  partition:
  Sdo_net.spatial_partition EXEC ('ITALIA', ' ITALIA_PART$ ', 10000, 'WORK_DIR_ITALIA', 'ITALIA_PART.log', 'a', 1);
  and for the blob of the partition:
  Sdo_net.generate_partition_blobs EXEC ('ITALIA', 1, ' ITALIA_PBLOB$ ', true, true, 'WORK_DIR_ITALIA', 'ITALIA_PBLOB.log', 'a');
  -J' uses LOD Java API for the analysis of network with Netbeans IDE. I took the code of the network NDM_tutorial of Hillsborough.
  
  My first analysis is the calculation of the shortest path between two extreme knots (about 1,500 km of distance) and two near knots (about 80 km of distance) using the algorithm of Dijkstra and AStar.
  I did the following tests on the execution time of the shortest path calculation:
  
  (1) with the score of 10000 maximum for the partition nodes (log file I read that generated the 1024 partitions with level 1 link):
  -between two extreme knots, approximately 1 minute and 50 seconds.
  -between two near knots, about 20 seconds.
  
  then I re-run two previous procedures where I changed the value of the maximum nodes for the partition and I did other tests:
  (2) with the score of 15000 maximum for the partition nodes (log file I read that have been generated 512 partitions with level 1 link):
  -between two extreme knots, approximately 1 minute and 50 seconds and sometimes it comes out of memory
  -between two near knots, about 20 seconds.
  
  (3) with maximum score 5000 nodes for partition (log file I read that have been generated 2048 partitions with level 1 link):
  -between two extreme knots, approximately 1 minute and 50 seconds and sometimes it comes out of memory
  -between two near knots, about 20 seconds.
  
  (4) with the score of 2000 maximum for the partition nodes (log file I read that have been generated 4096 partitions with level 1 link):
  -between two extreme knots, approximately 1 minute and 50 seconds and sometimes it comes out of memory
  -between two near knots, about 15 seconds.
  
  I think there is a problem because I expect lower execution times (maximum 5-6 seconds for extreme nodes).
  Even change the maximum number of nodes to partition the run time does not change much.
  I remember you that with memory on Oracle 10 g 2 approach the execution time for each calculation between two nodes is about 4 minutes and he sometimes goes out of memory. With LOD on Oracle 11 g 2, the execution times are reduced but are too long for me.
  
  Now, my questions are:
  -@Jack Wang: (if you read me) do you know what are the run time for the calculation of the shortest path between two nodes for USA network (about 1500 km away)? I remember that you used the LOD for the United States (56 million bond and 20 million nodes).
  
  -Do you think I have something wrong? How can I help reduce the execution time of network analysis?
  
  If you need more information just ask.
  
  Thanks to all in advance much.

  Could you please try setting the last input parameter 'regenerate_node_levels' true when calling sdo_net.generate_partition_blobs?
  EXEC sdo_net.generate_partition_blobs ('ITAI11_METERS', true, true of 1 ' ITAI11_PBLOB$ ', 'WORK_DIR_PROVA', 'ITAI11_PBLOB.log', 'a', false, true);
  EXEC sdo_net.generate_partition_blobs ('ITAI11_METERS', 2, ' ITAI11_PBLOB$ ', true, true, 'WORK_DIR_PROVA', 'ITAI11_PBLOB.log', 'a', false, true);
  Please let me know if it makes a difference?

• HP officejet pro 8600: software in place of the stands to check out more of network environment

  My printer was not scanning.  I uninstalled software and keys record, then downloaded the new software, but to put in place the stalls on verification of network environment, and he said: HP Officejet NO ANSWER.  After that, I start HP Print and doctor Scan, which said that the comprehensive software solution is not installed, so I went to install, but then I got the message "Unable to download". I tried several times in vain.

  When I go to devices and printers, the HP OfficeJet Pro 8 icon shows a yellow flag, then I will troubleshoot option but they do not find a solution for my printer.  I wonder if anyone knows a solution for my printer problems? The printer is less than 3 years.  Thank you

  Hi @yga and welcome to the Forums of HP!

  I see that you are looking to install the printer software. I would like to help!

  I would start with a power reset the printer.  Unplug the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug back in the printer. Make sure that you connect the printer directly to a wall outlet. Make sure to bypass any surge protector or power bar.

  Then, I would uninstall the printer softwarein case there is no residual software left.

  Once it is uninstalled, I suggest you put your system in clean boot mode in the configuration of Microsoft.  You can do this by following this document: How to perform a clean boot in Windows.

  Once the computer is in clean boot mode, I would suggest to reinstall the HP printer install wizard for Windows.

  Good luck and please let me know the results of your troubleshooting operations. Thanks for posting on the HP Forums!

• The installer crashes to check the network environment

  Could not print today. Deleted HP programs. Started more. Installation software downloaded from the HP website. All systems OK except when it comes to audit network environment of the installer crashes. My son and I are stumped. OfficejetPro8600, N911a.

  Contacted HP support. George sent the following. I worked through it and eventually won the victory.

  Hello Mark,

  Thank you for contacting HP Total Care.

  After reviewing your email, I understand that you have a HP Officejet Pro 8600 e-all-in-one printer, and this isn't anything printing place your computer.

  I regret the inconvenience that this issue may have caused to you. At the same time, I appreciate the effort you took to try to resolve the problem and also to be detailed in your approach. I will certainly try to solve the problem to the best of my ability.

  Cause

  This problem usually occurs due to some conflicts between printer and computer application.

  Analytical solution

  • Uninstall the printer software

• When I start the machine, continuous hard drive work for almost 1/2 hour, meanwhile if I open a program, the machine runs very slowly. Help solve the problem please

  I have wndow XP Home edition service pack 3 installed on my lap top. When I start the computer the hard drive continues to work for almost 1/2 hour; Meanwhile, if I open IE, or any program, the machine runs very slowly and I just can not open the program up until the drive hard light is off. Please help solve the problem

  How much RAM you have on your system? (Right click on "My Computer"-> properties)

  As a general rule, Windows XP does not work well if you have less than 1 GB or more of RAM.  What usually happens is that your RAM capacity is exceeded leading to overflow on virtual memory (the drive) to compensate for the need of RAM in the computer.  This causes your system to beat on your hard drive and slow down your system.

  If this is your problem, the options are to increase the RAM on your system or decrease the non-essential programs that launch at startup on your computer using a tool like Autoruns.

  Hi Jane,

  Yes, I'm having a great time. Thank you.

  Screenshots that you shared, it's an Atheros AR9002WB-1NG wireless network adapter.

  If you do not want to uninstall the old drivers I suggest that you try to update the driver from Device Manager.

  Even if it is not up-to-date, it won't bother the driver works.

  From the next page

  https://www.Atheros.cz/Atheros-INF-file.php?INF=423&chipset=31&system=6

  Copy the text from the [version]

  Use keyboard shortcuts, it's a file of confectioners.

  Copy the text into a Notepad file and save it as netathrx.inf

  After saving it GO to Device Manager right click on the Atheros AR9002WB-1NG, , click on the driver tab, now click on update driver, click Browse my computer for driver software, point to the location where you previously saved the netathrx.inf, select the file and click Next.

  The driver will be updated.

  I hope that this will solve the problem of unsigned driver.

• Difference between NAT vs vs Bridged, Host-only for the setting of my network card?

  When you use VMWare Fusion, what is the difference between NAT vs bridged vs Host-only for the setting of my network card?

  (Sort of related), if I use a VPN client on my guest will be Windows OS (as opposed to a my Mac OS host), who somehow reduce/limit the 'hooks' my company has also in my host operating system?  If so, I'm guessing that it then also prevents the limits / me being able to interact with my business from my host operating system environment?

  Thank you very much.

  KB link doesn't seem to work right now, so here's a basic response:

  NAT - Windows receives an IP address of one of the background merging services

  Bridge - Windows Gets an IP address from the same place as your Mac does

  Host just - isolated virtual machine of the world except the Mac.  (useful in development and testing of the configurations)

  NAT - Windows puts on a different subnet from the Mac, so the virtual machine cannot speak for the same things the Mac can talk with on a Mac network.  It puts kind of router between the Mac and virtual machine

  'Sex' bridge - essentially the same as the Mac, so you can access network shares, etc.  Good for enterprise environments where the virtual machine needs to talk to a network resource shared (AD, SMB shares, printers, etc.)

  Host only - yet once, isolate the virtual machine of all but the Mac, so no Internet, no Intranet, but he can talk to the Mac itself.

  Hope that explains things =)
