• vSphere 5 and Dell Equallogic iSCSI

  Hi all

  I need some suggestions on how to implement my iSCSI network

  I habe 2 x power R520 edges with 2 network cards to edge, 4 x PCI Nic and 1 x Dual Port Nic Cards-> network so 8 total

  and an Equallogic PS4100 with 2 controllers and 2 network cards on each controller

  I have 2 Dell switches for my iSCSI network.

  The address of the Equallogic MGMT is 10.10.1.100

  The group IP address is 10.10.1.101 - or should these IP in the iSCSI network

  My iSCSI network should be

  192.168.1.x / 24

  do I need to a single network or do I have to use 2 different networks in order to obtain the failover job.

  I plan 2 or 4 NICs for iSCSI vmkernel traffic - what do you suggest?

  If I use 4 network cards - use 2 vmkernel ports with 2 links and aggregation of links on the switches? Or can I use 4 ports vmkernel and round robin?

  ESX1

  vnmic0 192.168.1.1

  vmnic1 192.168.1.2

  ESX2

  vnmic0 192.168.1.3

  vmnic1 192.168.1.4

  EqualLogic

  eth0 192.168.1.5

  eth1 192.168.1.6

  ESX1 + ESX2

  vmnic0 - iSCSI01

  vmnic1 - iSCSI02

  SwitchA

  vmnic0 Esx1, vmnic1 ESX2, eth0, eth1 ControllerB controlled

  SwitchB

  vmnic1 ESX1, vmnic0 ESX2, the controller has ControllerB eth0, eth1

  Do I have to master two switches?

  Hello

  I recommend 2 virtual switches with 2 network cards in each. Multipathing in fixed for each switch if it's an active-passive array and Round Robin if it is an active-active array.

  1 VLAN should be fine.

  MTU = 9000 in all the components of your infrastructure iSCSI (jumbo frames).

  Try to have HA in each part of your infrastructure and you sure you don't have 1 vSwitch connected to the 2 ports on the same HBA and using the same switch...

  If you have the option to make the "fast track" in your switch, do it.

  CHAP authentication more secure, you can (if initiator software, I think that they are, mutual CHAP)

  You don't need chest 2 switches.

  Try to keep your number of VMs distributed among your LUN (to not collapse them with SCSI reservations)

  That's all I can think of at this time. I hope this has helped you! If that were the case, do not forget to assign the corresponding points, so we are all winners!

• Reference Dell Equallogic Interface errors

  Hi guys, I got a big problem here in my room. My equallogic iscsi interfaces have a lot of erros. What can be?

  

  First of all, make sure you run the latest version of FW and SANHQ table.

  Packet errors are often the cause of bad cable, bad switch ports and a misconfiguration on switch iSCSI ports.   The only way to erase the mistakes of packages on Equallogic arrays must restart the table.

  • Replacement cable between the controller port and switch port with known good cable.

  • 10 GB cables must be SFF-8472 compliant to work with 10 GB Equallogic arrays.

  • Confirm that the switch is a minimum firmware to work with Berry Equallogic en.community.dell.com/.../2661.equallogic-compatibility-matrix

  (Note: if unable to switch, you can disable protocols spanning tree on ports connect to the table).

  • Use the tech TR1017 report to verify the configuration of the switch and confirm it meets best practices.

  • Run a show of support on the switches to review port errors.   If a Powerconnect or Force10 switch then engage networks dell help examine the switch logs. If another provider, and then engage the seller to switch to help examine the switch logs.

  • Cards network host to firmware update and the latest network card driver

  • The direct link to TR1017:

  Media.Community.Dell.com/.../tr1017-v4-Network-Guidelines.pdf

  If the host Linux with Multipath.d, you may need to modify the multipath.conf file to include: tur path_checker in the devices section.

• Reattach the EqualLogic iSCSI for 2012 Windows volumes

  Hello

  We use EqualLogic, Windows 2008R2, HIT and initiator iSCSI access volumes. Now I'm re - install OS to Windows 2012. All materials, IP addresses, volumes, host name will be the same on the new operating system. BONES of some changes. Will it be the right way to remap the iSCSI volumes to the new operating system:

  1. on windows 2008 R2 take the volume offline in the disk management console.
  2. disconnect "Discovered targets" in the Windows iSCSI initiator.
  3 collect volumes offline in Manager Dell EqualLogic Group (to restore the connections).
  4. the new 2012 Windows Installer 4.5 HIT and set (is this version of the correct software for Windows 2012?)
  5 activate the volumes in the Dell EqualLogic Group Manager.
  6. Discovery target and connect to targets.
  7 collect volumes online in the OS disk management console.

  These steps are correct?
  Are they all necessary?
  Is a correct software 4.5 for windows 2012 HIT?

  Thank you

  Re: connections.  Are you referring to the iSCSI to table sessions?   If so, those are dynamic.  When you stop they will disappear.

  If everything is the same, so technically Yes.  Shutdown, you can reload and bring it to the top.

• ESXi 4.1 upgrade 5.1 in a Dell EqualLogic environment?

  Hi all, I am planning to upgrade our guests ESXi4.1 U1 to ESXi 5.1 Dell R610.  We use a PS6100E EqualLogic via iSCSI.  I installed 5.1 vCenter and prepared Update Manager with the image of Dell Custom ESXi 5.1, thinking that it would contain all the necessary drivers/modules.  However, after analysis of my ESXi hosts, I get the following caveat (see attachment).  Anyone has done an upgrade from 4.1 to 5.1 in a Dell EqualLogic environment?  I'm not warm and fuzzy about the procedure taking into account the warning.  Thank you!

  

  Hello

  There is no requirement for reconfiguration of re - install MEM after the upgrade.  It lies on the existing configuration as before.

  My personal preference is to uninstall 3rd party before the upgrade applications to make the cleaner process.  I don't know problem to upgrade to 1.1.2 and then the ESX upgrade, I have not tried it personally.

• Range Dell EqualLogic has stopped working when you restart the failure

  During and after an interruption of scheduled maintenance work, ESXi cannot mount on our Dell EqualLogic Array data warehouses and I have no idea why.

  We lack ESXi 5.0.  Shut down us throughout the weekend, replaced the network cables and when we returned to our ESXi hosts could not see the Bay EqualLogic iSCSI, but you could see several other berries on the same storage system iSCSI.  Digging into logs, I see the ESXi host making the CHAP authentication to the EqualLogic Bay, and the said table it connects successfully, then it loses connection about 10 seconds later.  10 seconds more ESXi tent reconnection to the EqualLogic and the same thing is happening again.

  I see several newspapers in ESXi hostd.log indicating this table goes ONLINE and off LINE and another line indicating "sense data Possible" leading me to http://KB.VMware.com/kb/289902 .  I feel really disabled at the moment because it's the Bay of storage accommodation our vCenter Server, which puts us in trouble right now.

  Also, if I try to "Add Storage", ESXi sees EqualLogic stores exist (watch a sufficient volume, size etc.).  However, as I'm trying to add them (via vSphere Client), step 1 takes a lot of time to finish, step 2 indicates the "disks are empty" (which I don't believe), then after an another long this timeout a popup error.

  Are there commands or utilities that are good for the diagnosis of iSCSI specifically?

  I can post more specific journal details if it is useful.

  PS - The new network cables are ok in communication with other storage targets, and it has not replaced the EqualLogic cables.

  Fixed; the MTU setting on my storage switch was mowing part of storage traffic.  Here are the troubleshooting steps that I went through, maybe it'll help someone else.  The solution didn't exactly have anything specific to do with ESXi or EqualLogic.  Basic troubleshooting and digging.

  Newspapers/events storage array inspection revealed he saw and accepted the ESXi host connection appempts.  I saw messages to the effect of:

  -Connection of ESXi iqn blah blah blah established; Successful CHAP authentication.

  -10 seconds later: Connection reset / abandoned by peers.

  -5 seconds later: ESXi connection successfully established...

  (rinse and repeat several times)

  Inspection of the file hostd.log ESXi showed several messages of 'connection reset by peer '.  The storage array and ESXi have been pointing to the other... so the switch is the only thing in the middle.

  Troubleshooting steps now:

  -using the vmkping ping on the table of the ESXi - success: vmkping 192.168.1.20

  -using the vmkping ping on the table of the ESXi with a size of 9000 (jumbo frame size): NO RESPONSE! : (vmkping) s 9000 192.168.100.20<-- this="" is="" where="" the="" money="" was="" for="" finding="" the="">

  MTU has been set at around 9000.  It turns out that the switch should be set a little higher (taking into account headers of packets? who knew)

  So this Setup ran for more than a year of intact working and just stopped when we took everything downstairs and brought it up.

• Reference Dell EqualLogic Multipath (e/s high flow)

  We recently bought a Dell EqualLogic SAN. Our main goal for this device was to begin to use pools of resources and be able to do a few HA and Live migration. We have worked with XenServer and Xen Cloud for a while and got no e/s on iScsi performance we were hoping for. With the help of Multipath on the main host machine we get on 250 Mbps (which we are satisfied). On the guest computers, we get only 120 Mbps.

  My question to the community of VMWare; If we wanted to use products VMWare is the possibility to get more then 1 Gbps i/o throughput on a guest PC? And if so, if it is a PDF or a post somewhere that could explain how to do this?

  Let me know, thanks!

  The doc of the correct configuration is attached... hope that her little help. In my view, it is also sub TR docs when you save your table PS.

• with vSphere and Dell MD3000i iSCSI design

  I installed a server ESX 4 (the first of three for this cluster), and a SAN Dell MD3000i iSCSI connected through two switches Dell PowerConnect 2816.

  Now I read the VMware 'iSCSI SAN configuration guide', and I wanted to just make sure I did the design correcly.

  I have connected a Teddy ESX (vmnic1) to one of the pSwitch and another (vmnic5) in the second. This pSwitch SAN iSCSI ports are connected, so that one of the switches carry the 10.10.10.x subnet and the other the 10.10.11.x (see IP plan below)

  The two natachasery have a vSwitch each (a do not share), a portgroup each and are configured on different subnets, IP (see attached screenshot)

  Plan of intellectual property:

  Port iSCSI-10 group (VMkernel): 10.10.10.1

  Port group iSCSI-11 (VMkernel): 10.10.11.1

  0-0 SAN controller: 10.10.10.10

  SAN 0-1 controller: 10.10.11.10

  Controller 1-0 San: 10.10.10.11

  SAN 1-1 controller: 10.10.11.11

  By using this configuration, I could see four different paths for each LUN. and I was able to make the ESX Server will switch to different switches/controllers as I unplug the vmnic1 network cables and vmnic5, one at a time.

  Then I found the section on 'esxcli' configuration guide and multipathing configuration, which I carried out in accordance with the instructions ("esxcli swiscsi nic add - n vmk0 d vmhba34" and "esxcli swiscsi nic add - n vmk1 vmhba34 d ')

  Now I have eight different paths for each logic unit number, three of whom are 'Active' and an 'active (i/o)' (see my screen attached the capture).

  So, my questions are:

  1. the eight paths to each LUN really normal in designs of iSCSI?

  2. is my vSwitch/Teddy/pSwitch correct design choices?

  Thanks in advance!

  / Anders

  @hennish,

  As long as your new design continues to meet your needs of failover and workload, your infrastructure design should be fine.

  But you might want to take a look at this design Dell. In particular, step 12 that configures multiple paths in round-robin policy using the VI GUI client, for

  Each LUN exposed to the ESX Server. This allows balancing on two

  Active paths to the LUN. After completing this step, you should see2 "IO Active" paths.

  Kind regards

• Dell Equallogic PS5000X NIC reference

  Hello

  does anyone have experience of SAN Dell Equallogic PS5000X?  I'll put in place at the moment and it seems there are 2 controllers for all of the 3 NIC (6 in total).  I find I cannot use 3 cards and 1 controller in Active mode and can not find a way to get the two controllers to work in unison and the two assets.

  I wanted to use 4 network cards for iSCSI traffic on a VLAN giving a rate 4 GB of storage but you can use 2 network cards, giving a throughput of 2 GB and 1 for management.

  Is this the only method available for this type of SAN?

  Any advice would be greatly appreciated.

  Andy

  Hey,.

  The PS is an active / standby. A controller is active. The other will be the shot if the first of all a problem. You have only a configuration to do.

  You configure 3 interfaces in the GUI. eth0, 1, 2.

  The second controller will use this interface when you need.

  You can dedicate a management port, but Dell recommends that you connect all of your ports to the ISCSI network.

  Hope this helps

  Please consider my response as 'useful' or 'proper' marking

• Recommendation of RAID for Equallogic iSCSI SAN?

  We look at a Dell/Equallogic PS6000E with 16 drives of 1 TB, it connects to our servers ESX 2-3 (about 15 virtual machines running) and to a SQL cluster (mainly a SharePoint service workload size).  Dell recommends RAID5, which would give us ~ 12 useful to.  Frankly, if we had used 8TB, that would be fine.  Any recommendations for the best RAID for Equallogics level?

  Thank you

  Chad

  If you can really just 8 to, I must say raid 10...   Reference Dell suggests always raid 5 no matter what.

  Now best practices is to create several groups of disks with different raid levels for the taste of storage at your fingertips.

  You are going to have to make some calls to judgment on how to implement.     I suggest you test conversions PtoV tour and play with the config some before deciding, but I know that it is now possible in most cases.

  Dell has an excellent white paper on the table.  It's for the MD3000i, but the raid types and most other info still apply to the DAS or san during raids.

• 3 Dell Equallogic PS6010

  Hello

  I have 3 Dell Equallogic PS6010 Raid 6 accelerated what is the optimal configuration for performance and reliability. Should I put all members in the same pool with some volumes? using this configuration what happens if one of the members die in the pool volumes will still be online? Or do I have to create a separate pool for each Member and syncrep everywhere?

  Thank you!

  Hello Quackattack,

  If you have several members in the same pool, then default data for each volume to be spread out in the members.  Up to three by default, unless the volume is too large to fit on only three members.

  So in the case of Member failure, all volumes in common with this member will go offline until the table is restored to service.  Members in the same pool work together so that will give you the best performance, but at a greater risk.  The berries are extremely redundant to prevent this.  Also, members in a pool even with permutation of the blocks to keep the I/O latency to the balance between the members.  If a member with a lot of IO will send blocks occupied another Member and take blocks of slow motion of this member.  Keeping the latency in space and tick as well balanced.   It's advanced performance load balancing.

  But if this is a priority, then put them in separate categories would be better.  You would have to manually manage IO loads to prevent a pool being saturated, while others might be slowed by comparison.

  You can also do a combo.  Put two members in a pool, then someone else in another to the syncrep on your volumes. Giving you a balance between too.

  Much depends on the load that you expect to apply to the group.  In addition, if you can levarge improvements EQL MPIO, like MEM for ESXi, HIT / THE for Linux or HIT / ME to Windows.

  If you use ESXi, VMware requires also to company or company + to run MPIO extensions like MEM.  If you cannot use MEM, then this PDF has info on how to improve fuction MPIO using VMware standard Round Robin.  As well as other tips as well.

  If you haven't already done so, install SANHQ v3.x to better monitor your group (s).
