• Migrazione SAN - FC SAN - SAS

  Hello to all,

  HO a client currently has una configurazione che con singolo e storage FC Dual Controller is al server point to point.

  Vorrebbe una soluzione completely nuova:

  2 host nuovi

  1 SAN in SAS

  Così da poter utilizzare HA; HA una essential Plus licenza gia.

  Domanda, qual'e seconda vostra esperienza, the best solution by migrare I datastore da una SAN - FC ad una nuova SAN - SAS?

  Grazie in pre-empted by the risposta

  UNA possibility it could essere questa:

  Enter una sul vecchio SAS hba hosts.

  Colleghi it nuovo presenti nuove lun storage.

  Tramite Storage vMotion migri the VM. Per farlo a tipo caldo ti will serve una licenza Standard. You can use Eval una.

  The sposti oppure a freddo.

  POI colleghi I have Microsoft host al nuovo storage nuovi. Migri tramite vMotion VM.

  Server Elimini it vecchio.

  SE non you can take una hba in più, una delle nuove ricicli e fai a cluster a temporary 2.

  Spero di essere stato chiaro

• HP Envy 15t: ads by SASA

  Hello-

  Have a little problem on my new machine.  I started my work software installation process.  Somewhere along the line, I picked up some malware that appears in the form "ads by SASA.  Much of appears and displays now show.  I have run several types of malicious and spent an hour on the phone with the concierge service and I can't get rid of this malware infection.  I also searched internet and nothing I can find really works.  Looking at the control panel and all the programs that are installed, there is nothing suspicious.  Does anyone have any suggestions?

  Things I'd like to try but may not know:

  -I want to reset IE 11.  I went through these steps, but in the end, I have a red X (that is to say, fail) on reset customizations.  How can I make this?  Of course, the malicious software has somehow obtained in IE.

  -J' have another program scrub of malware which like to use my work COMPUTER service.  He works outside the Windows environment but requires that I boot on the USB bootable.  I tried and tried to make the computer do cela, but do not understand how to change the BIOS to do this.  I want to run the other program.

  -Finally, if none of the above works and there are no other options, I think I'll have to do a factory reset.  Not too big of a deal, but all the programs that have been installed by my computer work will need to be reinstalled.  All other programs I have installed have disappeared.

  Thanks for any help.

  Hi Kurt,.

  I know how frustrating it can be, I spent all the way.

  However, after a few attempts, resolved in this way, for me, and after that for some of my friends:

  Emsisoft and Malwarebites are free to use, no need to buy them. You can download, scan and remove malicious software free of charge. You pay the option upgrade to the pro version which offer protection in real time, I do not have, and I want to advice to anyone.

  Malwarebites has taken time to find malware, Emsisoft have a smart scan option, so it takes less time to find and remove.

  After that, I have run Ccleaner, clean cookies, temporary files and other places where traces can be hidden.

  After that, IE restored without problem.

  If stil you want to run your program scrub of malware you mentioned before, it is good to take a look at the HP document:

  http://support.HP.com/us-en/document/c03736054

  I'm sure that you will solve your problem.

  BTW, my PC where I have the same problem was an asus . Solution to this problem was not found on their forum.

  All the best!

• Best Poly Fit Coefficients do not match the best Poly Fit 2

  Hello

  I have dataset with 9 points and want to adapt or to solve linear equations with coefficient 9. The model - equation is then

  Z = a0 + a1 * x + y * a2 + a3 * x ^ 2 + a4 * x * y * + a5 * y ^ 2 + a6 * x ^ 7 * x + 2 * y * y ^ 2 + a8 * x ^ 2 * y ^ 2; coefficient 9 total EQ.

  When I create the matrix H and send data to 'General linear Fit' it returns coeffcients and the best fit. Better adapt works well but I don't know how to interpret a coeficients.

  All the math of it works well when the function is second order polynom, for example, when there coefficient a0 to a5.

• Guidelines for best performance MS SQL server on EQL

  Hello

  Currently, I have a VM that the C: drive of the system as a disk VMDK on a LUN in a table of PS6100XV (24x600GB 15 k SAS drives).
  This logic unit number is shared with other virtual machines.

  The data and logs is on the D: drive which is a MS iSCSI initiator attached volume on the same table of PS6100XV.

  I think to create two volumes on the Bay and move the data and logs to the respective volume. Will this increase performance or it won't make a difference because the table is a part of 24 disks with a pool. What about braces?

  Can I create different pools and put the different volumes on these pools so volumes using different storage arrays which gives best performance? What is the optimal configuration of the eql to host SQL volumes?

  Thank you

  You certainly want to separate EQL volumes for logs and data.   It was a best practice for a long time, with or without virtualization.   The operating system has a queue of SCSI for both of these "readers" since there is in fact only a single drive.

  If you have not already you must configure the EQL MPIO customer volumes and install HIT / ME software, available on the site Web of Equallogic.   That will optimize the I/O of these volumes.

  If you do that a single physical Bay, you can have only one tank.  If you have two arrays of members, you may have one in swimming and one in the other.  There is no way to split a single physical table on more than a pool.

  Kind regards

• Upgrade the disks in RAID 6 array: what is the best

  I have a Dell PowerEdge 2900 running Windows Server 2008 R2 and 6 x 75 GB 10K SAS drives.  PERC 6 / i controller RAID 6 with 5 drives + HS 1 (total 6 discs)

  I have 6 x 300 GB 10K SAS drives ready to trade.

  I read everything I can on hot swapping etc and what I can't find is any method to close the front discs actually pulling them.  Supposed to be via Computer Manager-> storage but not here?

  Restarted, Ctrl + R, in the controller BIOS, nothing there either.

  I have therefore 2 options:

  (1) go for it, just pull up a disc and put in a new and let them rebuild.  Repeat x 5

  (2) stop, change the music, etc.  I don't like to stop a perfectly functional server...

  Looks like #1 would be better, but without the stop disk option I'm not sure...

  Then there is the whole operation in general.  It is best to:

  (1) hot-swap & rebuild

  (2) make a backup to disk image, on all readers of a sudden and restore?

  Looks like #2 would be better... but I don't still need to re - install the software on the array of naked?

  Hello

  budcarlson

  I read everything I can on hot swapping etc and what I can't find is any method to close the front discs actually pulling them.  Supposed to be via Computer Manager-> storage but not here?

  The operating system has no control on the disks. The drives are controlled by the PERC. You must use either a software that allows the management of PERC as OpenManage Server Administrator or boot directly on THE controller's BIOS.

  You should have an option available for the physical disks offline before removing a table. Which will allow you to remove a disc without causing data corruption.

  The best practices and the method supported is to back up the data, create a new RAID array with new drives, reinstall, and then restore the backup.

  Hot swapping and reconstruction are the best way to do this, but the simplest is not the best way. If you choose to rebuild and hot-swappable, you will also need either to create a new RAID array (sliced table) to use the new space or change the markup for the table.

  Thank you

• SAS HBA or Raid for R905 for external storage?

  So I got a R905 used off ebay.  I wanted to use it for a storage server.  Unfortunately, the LSI SAS HBA or the Areca 1883 work in one of the 7 pci-e slots.  The cards are seen and their bios are launched and start automatic and other tests.  Two of them crash during initialization (it is not a matter of waiting a few minutes - in a trial, let him so all day while I was out).  I know that the slots are not dead, like the map 4-port gbe enet provided with it works great, just like a connection-x 2 infiniband card.  I confirmed that the bios and bmc firmware are the latest and best.  It's a kind of dell 'we do support the controllers dell' thing?  If so, I guess I agree with the purchase of a dell SAS HBA connector sff-8088 with random (since that's what jbod I want to connect using...)  Any thoughts appreciated...

  Hello.

  No Dell non-certified controllers are not validated to work properly on Dell servers. But this does not mean that may not work, it's a 50-50 chance. I recommend using certified Dell SAS HBA card such as: manufacturer: 7RJDT | Dell reference: 342-0910. Not so sure on the type of connector

• Best VPN debugging commands?

  Hello

  I was wondering what your best VPN debugging commands are on an ASA or the router about the phase 1 and 2 and the ACL?

  For example I have a site-to-site between 2 ASAs and phase 1 and 2 are on the rise, but each site cannot ping a PC on each site.  I'm looking to NAT and ACLs for the moment, but all useful commands would be most appreciated.

  Thank you

  Two 1 go - to orders are:

  ISAKMP crypto to show his

  Crypto ipsec to show his

  If the Phase 1 and Phase 2 are not upward by these respective commands, then go to:

  Debug crypto isakmp 7

  Debug crypto ipsec 7

  You may need to increase the verbosity level (255 is the highest) and, if you have multiple SAs, focusing on those that you are interested in with a filter:

  Debug crypto peer condition

  Once you have Phase 1 and 2 but established that you are experiencing persistent problems with two-way traffic flow, look at two things:

  1. at the exit of his see the crypto ipsec, decaps proportional increase with the program. If this is not the case, the remote line can't get the return traffic. Confirm with a capture of packets and/or track.

  2. use the command packet - trace (CLI or GUI) on the SAA to review how it will handle a given stream. NAT and ACLs questions often are quickly visible using this tool.

• Love tunnel SAs negotiated, but do not survive.

  Background

  We have a stable P2P GRE + IPSec configuration to multiple rays using signatures rsa for authentication ISAKMP and EIGRP as the routing protocol. We are in transition to a love (DMVPN) configuration. GRE P2P tunnel interfaces are administratively shutdown, cryptographic cards on physical interfaces have been removed and the cryptographic database has been erased.

  Question

  When implement us the interfaces of tunnel love (Star), we are able to complete the ISAKMP phase I and II (briefly). However, ~ 1-1/2 minutes more, we see a message from debug on the hub, such as:

  13:56:49.601 Jul 21 EDT: IPSEC (cleanup_tun_decap_oce): Unlock and null to Tunnel0 tun_decap_oce 86742E48 of 86FB990C of ident

  ... and then the IPSec SAs are deleted, the tunnel down, IKE_PHASE2_DEL and IKE_PHASE1_DEL messages are generated and start with phase I ISAKMP negotiation.

  Anyone know what the 'CEO '?

  You are right your comment.

  The previous interface of p-BRMS (in your case) can get his information in to

  the tunnel endpoint database (packages of controls tunnel) even if the

  p BRMS tunnel is stopped.  It is also in the code a GRE packet

  destined to the router will search a mathc with a p-BRMS tunnel before

  Love tunnels. If the GRE tunnel packets were getting "caught".

  by p-BRMS tunnel and then dropped.

  If I really want a GRE tunnel to be 'down', I'll remove the "source of the tunnel...". ».

  If I have two tunnels upwards at the same time, I do what you do, give

  each of them a different tunnel key or a different source of tunnel.

  Hope this helps to understand what was going on.

  Mike.

• T310 with sas 6/ir controller replace has no disk in raid

• SAS/SATA mixed pool and initial data placement

  Assuming that I have a mixed pool of SAS and SATA drives, where new written land?  My concern is that Scripture arrive on SAS and SATA also and then over time the SATA data would be transferred to SAS has high performance and data on SAS are cold it shifts to SATA.

  I'm leaning toward a configuration that initially all written in SAS assuming it must be efficient and then over time, move down to SATA.  It seems that this is possible.

  I am looking for clarification and perhaps a document that could help me understand how to set up my table for everythying lands on fast and down to slow down over time.

  It does not work like that.    When you have several members in the same pool, the data is distributed across members in proportion to their relative sizes.   So more data on the volume will reside on the SATA member since he will be probably larger disks.   This is especially true is the SAS is R10 and SATA R50/R6.   Which is pretty common.

  In the 5.2.x, firmware if berries are very busy most of the time, the balancer will swap blocks filled with blocks of idle until they members have better balanced latency.  Short term transitional IO load balancer will only be active often.

  You can set preferences RAID in volume, if the members are at different levels.

  You can bind a volume to a member of the one.

  However, the best thing is to start with the group with SANHQ monitor.  This will help you find what type of i/o load you put on the group.   In addition, if you open a support account sometimes this data is also valuable to support.
