• Reference Dell acceptable EQL PS4100xv latency

  Hello

  I had a Dell PS4100xv with 3 three servers connected via 2 x PC6224.

  The total consumption of the IOPS / s does not exceed 600 IOPS / s. Most of the OPS / s time is about 300 IOPS / s. In looking at SAN HQ, OPS are / s taken max supported by the table on the RAID 6 should be about 1500 ms.

  The latency is about 20 to 50 ms.   However it reads about 80 to 100 m, but it is not maintained.

  What is the acceptable latency for the EQL? I have Windows 2008 R2 SP1 and some Linux virtual machines.

  Application performance is acceptable.

  Thank you

  Paul

  OK, that will certainly be delayed ACK and / or LRO.  In addition, should check that MPIO has Round Robin with IOs by path to 3.  (Default for RR, 1000 IOs before moving paths)

  This link is a PDF which covers all the best practices for ESX + EQL.   There are some very important parameters for the performance and redudancy in this guide.

  en.Community.Dell.com/.../20434601.aspx

  The question of priming is probably different from the issue of latency.  Given that very few of IO to the SAN occurs during startup.   If you look at the EQL GUI, you can see the speed at which the connections met.

• frozen MacPro startup

  While working online screen of my MacBook Pro suddenly went grey. I turned off by holding the power button, and then he started upward. He would charge the Apple starts the bar and after it went down to about 1/3 of the way suddenly turned. I tried a few times and then opened it in safe mode. Ran repair disk and after having received the message in green "everything seems to" correct the screen froze. He said there were five minutes to go and I waited at least 20 minutes. I then typed my mouse and the Rainbow ball began the round and I've waited longer until I turned it off again. I tried to go back to the top and got a flashing question mark inside a folder. It off and starts in safe mode this time the Bar starts but remains stuck at halfway through and will not move. Any suggestions what I can do? Thanks for your time!

• Computer reboot at startup guard

  This summer my Mac (3.1) behaves very strange;

  When I start it in the morning, it restarts (by itself) 2.3 sometimes 4 x every morning I start.

  The interval varies between 10-30 min max and maybe 30 seconds.

  After that, he works all day - in the evening without a hitch.

  I have to admit, we were always with high humidity.

  And the problem started this summer.

  When that I start, I let him settle for a while, but again it restarts.

  I wonder, what could cause reboot?

  My guess is material...?

  I plugged 4 disks from Drobo, but I do not think, they might be the problem.

  • Note the time of the next involuntary reboot. After the reboot, open the Console app in Finder > Applications > utilities and look for entries of the log at the time of reset. Suspicious message here.

  Search before the journal entry that begins with BOOT_TIME since it is the first line of a startup

• At startup, the Apple iMac logo flashes red after update to Mac OS Sierra

  After upgrading to Mac OS Sierra, my 2015 iMac 21.5 retina has a flashing red Apple logo, then a brief splash screen flickering when starting. Once started, the computer seems fine, with no obvious debris. I don't know why the logo flashes red and then the screen flickers - bad drivers; a problem of software in the start-up phase; a problem with the drive of the merger; or maybe some other gremlin? A quick search on the internet reveals that at least a few others have the same problem with this version of the OS, and it seems to have occurred in the years spent with any other version of Mac OS upgrades. But there is no good answers on how to fix this. I rebooted several times hoping it would clear itself, but no luck.

  Safe Mode boot removes the system caches that can help after an update or upgrade.

  Follow these steps to start in safe mode.

  1. Start or restart your Mac.
  2. As soon as you hear the startup tone, hold down the SHIFT key.
  3. Release the SHIFT key when you see the logo Apple appears on the screen.

  After the Apple logo appears, this may take longer than usual to reach the login screen or your office. This is because your Mac performs a check of directory of your drive to boot in safe mode.

  To leave safe mode, restart your computer without pressing any keys during startup.

• MacBook Air wouldn't startup after starting get disk error

  I was getting full boot disk error on my Macbook Air 2012 model a few times, and then it stopped starting (folder flashing with question mark began to appear). I followed the instructions on this site If flashing question mark appears when you start your Mac - Apple Support

  but failed to copy data from the drive on an external hard disk. I could see my boot (MacintoshHD) on the disc utilities drive, but could the volume seems to be not mounted.  The size of the disk is 128 GB and only 12 MB seems to be free.

  1 has started the macbook in recovery mode. In disk utility, run check disk and repair utilities disk for the startup disk (MacintoshHD). No problems in the generated logs. The volume is not mounted and is dimmed.

  2 selected MacintoshHD and tried to unlock it. The system tried for a while, and the password window disappeared after some time with the MacintoshHD via disk utility.  When I restart the machine again in recovery, disk MacintoshHD reappears in the same situation.

  3. I was able to start the macbook after installing a new version of OS X in an external hard drive. During the installation of OS X, I couldn't copy the data from the volume MacintoshHD (possibly the drive is locked).

  4. I could not start my macbook in safe mode.

  My query is-

  1. I had not backed up my data by any means. What are my current options to copy my data MacintoshHD?

  2. because the MacintoshHD is locked and attempts to unlock it had no disk utility, it will help if I start my macbook target disk mode, connect to another mac via a thunderbolt cable and try to copy data?

  3. What are my options now to restore my macbook? Clear my boot drive (MacintoshHD) and reinstall OS X?

  Thank you

  Is it possible to disable services icloud, icloud photo library and icloud 10 PC Windows startup disk? There will be negative consequences if I disable these at startup?

  You can uninstall iCloud for Windows completely if you do not use one of its features. If you do, you should let its services run. See what is iCloud for Windows?-Apple Support for more info on what it does.
