Latency on LUNs SAN whats your opinion?

Fellow community,

 

I've opened a ticket with VMware but wanted to get your opinion as well.

 

When looking at "physical device read latency" I'm seeing 570ms.  And I'm seeing high numbers across multiple LUNs on different hosts.

 

I see "storage path/real time" read latency hitting 570ms.  Path latency matches the "physical device read latency"

 

I see "physical device command latency" numbers at 63ms.

 

When I look at "kernel command latency" its either 1 or 0.

 

"Storage adapter read latency" is hitting 38ms. 

 

Would you agree that we are experiencing SAN latency or fabric latency?

ARP cache on virtual switch

We have three separate VMware SQL 2016 AlwaysOn clusters running on vShere 5.1. We noticed on all three clusters whenever we'd fail over a Availability Group to a second node within the same VLAN and running

on the same ESX host, that the resources would not become available until a 15 minute time-out period. If we fail over the same AG group to a host in another building the resources are immediately available. 

This only happens on the same VLAN. So we opened a ticket with Microsoft and they ran a trace and stated the arp request is being sent out but no replies are being returned. Is this a vSphere issue?

Where in the process does VMware update the arp table?

Start info:
- 5.5 Vmvare
- Motherboard Supermicro SYS-6028R-C1R 19 "2U
- Raid is built SAS 12Gb / s LSI 3108 RAID 2GB with optional CachVault (RAID level 10)

vROps SQL Monitoring - Security Permissions and issues discovering/monitoring DBs

September 7, 2016, 1:42 am

Hi All,

 

We are struggling to identify the correct set of permissions required to be able to monitor SQL instances and DBs in our estate. This is a 2 part question/issue, so bear with me

 

1)

What permissions are required to monitor both SQL instances and DBs? So far, we have the following assigned to our AD service account:

 

Windows - Logon Locally, Logon as a service. (As it happens, the service account is local admin, so shouldn't have any restrictions)

SQL - View Any Definition, View Server State, and also db_datareader on MSDB/MODEL and each user database.

 

In some cases, we're getting monitoring on the instance but not on the DBs, others we're not getting any monitoring at all. It seems very random, but permissions are consistent as far as we can tell.

 

 

 

2)

We have 2 vROps instances - PROD and NON-PROD. Both are identical versions, levels and policies, using the same version of the plugins.

 

In NON-PROD, we are able to discover SQL instances and the child databases.

In PROD, we only see SQL instances - there are no child objects - Checking inventory explorer in both environments we can clearly see that there are no objects of type MSSQL Agent, Analysis, Database, Databases in the PROD environment. Before anyone says anything, they DO exist!

 

How can this be? Is there anything we can check? Bit stumped on this one....

Has anyone taken 3V0-632 - VMware Certified Advanced Professional 6 – Cloud Management and Automation Design Exam yet.

Wondered what the general feedback on it is. Is listed as 23 questions for 3 hours so assuming some complex scenarios. Particularly interested on feedback from non VMware employees as to whether the "public" stuff available is sufficient to pass this one.

Hiya,

 

We're setting up a virtual appliance for vCenter Server and despite my best efforts, I can't find any information relating to HyperV compatibility.

If anyone could advise that'd be awesome!


Is HyperV supported by this and if so, how would we go about setting this up?

 

Many Thanks ^_^

vHost Vendor Drivers

Hey all,

 

I have been running a vhost environment for several years and sadly to admit I am very poor at keeping the vendor (IBM/HP) drivers up to date like I believe I should. I have been lucky and only ran into 2 or 3 times where a NIC driver or something on the vendor end caused a problem.  I am just wondering and asking for advice on how others keep theirs up to date, so I would love information like:

1) What sites or email list to do check to hear about drivers that I need to update?
2) How often do you check?

3) What is the best method do you use to deploy the updates? (USB key, some method to push updates, or something else)

 

Any help or extra advice would be GREATLY appreciated!

Keystore issue with HTML Fling SDK

Hi,

 

I was just trying out teh new HTML Fling SDK. I was following the steps from Getting_Started_with_HTML_Client_SDK_Fling.pdf.pdf.

 

I completed the setup steps and did the vCenter Server registration. But when I try to verify the steps of vCenter Server registration, it fails with below error on the browser (https://localhost:9443/ui/login):

A server error occurred.

[400] An error occurred while sending an authentication request to the vCenter Single Sign-On server - An error occurred when processing the metadata during vCenter Single Sign-On setup - Keystore to be used for remote connections is null..

My VMWARE_CFG_DIR is set to C:/ProgramData/VMware/vCenterServer/cfg/. I have also attached the vsphere_client_log.log.


I see couple of errors in the log, but not sure how to resolve them.

DirectDraw rendering on multiple monitor Horizon View Client

September 13, 2016, 8:43 am

Hi,

 

I am supporting a Windows application that uses DirectDraw to draw a 2D network diagram.

 

On the second monitor of a Horizon View PCOIP client, the diagram does not update (refresh) at all.  On the primary monitor, the diagram updates absolutely fine.

 

The application defines directdraw surfaces and a clipper to prevent overwrite of windows/foreground display.  It blits the network diagram raster from secondary surface (background) to primary surface (screen).  For investigation purposes we commented out the creation of the clipper.  In this case, the second monitor updated as expected, but with the obvious side effects of not using the clipper.  It therefore looks like there is a problem using a DirectDraw clipper with multiple screens on this virtual graphics driver.

 

Has anyone got similar experience?  Are there any settings on the virtual graphics driver that could resolve this?


Thanks,

Tony.

Use vRealize Operations to get VM snapshots and date taken

Hi,

 

I'm using vROPs 6.2 and I'm building health reports. One of the things that we really would like to know is which VMs have a snapshot and what date the snapshot was created on. I'm halfway there with the "Disk Space|Snapshot Space" Metric. However I cannot figure out if it is possible to tie a date to when the snapshot was created.

 

Is it possible to use vROPs to find a date when a snapshot was taken? and if so could you provide me some pointers?

 

Thanks,

vSphere MIB to check NTP?

Good morning, all!

 

I'm extending our network monitoring to include our ESXi 5.5 hosts.  Using Nagios and SNMP, one of the objects I want to monitor, or at least find out where, is the NTP connection. If the host loses contact with the NTP provider, is there a parameter in one of the MIBs to check NTP connections?

 

Thanks!

Best solution for Cross vCenter Parent image sharing/replicating ( Cloud Pod architecture Horizon 7 )?

September 13, 2016, 9:24 am

Hi guys

 

I am doing a Cloud Pod Architecture for DR purposes with  2 vCentres/cloud pods  A and B , trying to share Link Parents from A to B , I don't mind replicating them all over to B if I have a good method,

 

These vCenters are on the same LAN and network , 

 

I was looking at Content libraries but this seems a lot of admin as I have 30 Link parents, and content libraries only works with templates, so i'd have to convert to a template to transfer, then out of the template again to recompose/make the DR Pool

 

I guess Veeam is an option ?

 

Or is there a way that I can make my cloud Pod B see the link parents in A ? vCenter linked mode perhaps?

 

Bit confused by this and hoping I don't have to go through the content libraries method ,

workstation 12 much slower after win 10 "anniversary" upgrade

The difference is dramatic, near the point of unusability.

 

The laptop has 8GB RAM. The VMWare virtual machine has 2GB.

 

An Adobe Acrobat PDFmaker task in the VM is more than an order of magnitude slower than it was before the update.

 

Anybody understand why this might be so, and what can be done about it?
