• Need help with network home using Airport extreme

  I need help with my home network.  I'm not very aware when it comes to all things network.  Here's how my network is currently set up.

  Cable modem to Airport Extreme for Gigabit Switch.  Cables come out of the switch to all areas of the House.  I have 2 other extreme airport connected in other rooms of the House directly on the wall that dates back to the switch.  I hope I am explaining that properly.

  My problem is that this seems to have caused some of my connections cable does not work.  When everything is configured, it has worked well.  All connections in the House worked.  Then we have disconnected one of the extreme airport and moved to another location in the House to have the best wifi coverage.  Since that time, a lot of the ethernet wall plugs are not working.  For example, when I plug in my Macbook Pro in making ethernet in my kitchen, it says connected but it has an assigned ip address and cannot connect to the internet.

  Any help you can provide would be great.

  I would like to get the return tech to help you to...

  But it is likely that something (or someone) has tampered with the settings.

  The layout is fine... but you can cause problems with the network by creating a loop.

  This can happen because the AE you moved is connected wrongly... somewhere in the network it is connected to the switch again.

  Or AE is set to expand wireless... It's FAKE... It will loop the network on the back main EI wireless.

  Unplug the two AE you have that function as extensions...

  Turning off everything else... then it works again...

  Do it in this order.

  Modem... Wait 2 min

  AE... Wait 2 min

  Switch.

  Now check that the network is working properly... power of customers in various locations and make sure everything is good.

  If so, then manually reset the two AE of factory and redo their installation.

• Need help with my hard disk configuration

  Hi guys,.
  Ive read a lot about the best configuration of hard disk for my editing video pc... but I need some feedback. Here are my specs. Im running Windows 10 with this HD configuration. I use my system for Premiere Pro, Photoshop, Lightroom, and After Effects.

  1 SDS drive 250 GB operating system, program files, swap file

  2 HDD (sata III) of disk 2 TB stockmedia / assets / my documents

  Disc 3 HARD drive (sata III) projects 2 TB

  4 drive HARD drive (sata III) 750Go export/renders, PP previews

  5 HARD drives (sata III) of disk cache AE, PP, scratchdisk photoshop, captured 750Go audio/video media cache

  
  

  If it would be really beneficial to my performance, I also have another HARD drive disc (sataIII) 2 TB which I could build in the case.

  It looks all right? Or you guys change anything? I have a RAID configuration, but what I understand... RAID 3 or 5 would have need of more disks (same size preferred) and preferably a hardware controller. But my budget will not allow this for now.

  Thanks in advance for your comments guys...

  You probably already read this, but if you do not page Tweakers: Disk Setup

  you drive configuration looks good, you can use the windows resources monitor to determine if the readers are struggling as well.

  If I had to change something, I would try 2x2tb raid 0 (disk 2 and 3) for media/assets/projects using mbd raid (if your mbd supports raid). I might even try to add the spare hard drive 2 TB, 3x2tb RAID 0 for performance even more. If 'my documents' is just random storage (not for your active video projects), you can move to another drive out of the raid, as the 4 drive or another room to spare. Since you already have these parts, raid can be a good way to boost performance for free. any raid can add some risks more data loss, so you just make sure that your backups stick to the currents. You can save a copy of the project first (just the file .prproj) in a few different places at the end of your editing sessions, or use auto-enregistre to another location, to avoid having to save as much.

  Moreover a unique fast sata ssd is comparable to 3 hard drives in raid, so you could look (s) ssd, sata for better cheaper and simpler vs an expensive hardware raid card. SATA ssd prices keep falling off and show no signs of slowing down, so if/when you get some later, they could be even more affordable.

• Need help with the disks 'unreadable' configuring software raid after the death of the startup disk and system restored.

  I'm looking for some advice on how to restore a windows xp installation software raid 5 that was running on my XP system. I had a problem when the startup disk has failed, but I was able to backup the system before it can. I replaced the drive and restored the system and everything came, but I was not smart to do this and accidently left the readers connected when restoring raid. I don't know if windows has done something when I tried to install XP on the new drive, or maybe something else has happened when I restored the system from the backup, but my raid drives can not be used. There was a moment in the restaurant business I saw a message on the MBR, but I thought that was just for the drive being restored. I didn't have a single player who held any information on the other disks in the system, but I'm not 100% sure on that.

  When the system boots the windows logo screen takes 10-20 minutes before you get on the desktop. Windows Disk Manager takes 20-30 minutes to fill the list of drives and status on the disks three raid is 'dynamic' and 'unreadable' is not reassuring. I suspect it's a problem MBR or partition table that must be corrected before trying to reactive the raid, but this is just speculation.

  The raid drives are on a promise ide/scsi disk and make it appear to start correctly with names and sizes. After that I get nothing. I do not have another scsi controller (or), but I thought I'd try active @ partition recovery to see if she can find information on the disks.

  I hope someone has some experience with recovery like this, because this is a first for me. I thought I was pretty sure running a raid-5, but wouldn't you know, the tech gods have found a way to crush my plans...

  Thanks in advance for any help!

  Both are related to the use of aggregation running on your vCenter

  Historical data interval 4 are grouped once a day, and on your vCenter this SQL task seems to be planned at 08:00.

  That is why the time stamp.

  Statistical data are aggregated to one historical interval to another.

  Since ask us the historical interval 4 (with the IntervalMins parameter), the aggregagtion to this historical interval is not yet made.

  This is why the last day 2 are not present in the report.

  You can play with the - Start and - finishing settings to have a period of 7 days which is at least two days yet at the time.

  $report = @()
  $metrics = "net.received.average","net.transmitted.average"
  $vms = Get-Vm | where {$_.PowerState -eq "PoweredOn"}
  $start = (get-date).AddDays(-7)

• 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.

  Can someone please help me to write this query?
  
  Thank you

  Thanks for the test of the configuration!

  SQL>SELECT   t.NAME, COUNT(*)
    2      FROM topic t, blogpost_table b, post_table p
    3     WHERE b.topic_id = t.topic_id
    4       AND p.post_id = b.post_id
    5       AND p.datepost >= DATE '2009-07-01'
    6       AND p.datepost < DATE '2009-08-01'
    7  GROUP BY t.NAME
    8  ORDER BY COUNT(*) desc;
  
  NAME                   COUNT(*)
  -------------------- ----------
  baseball                      2
  soccer                        2
