It is supported on the Nexus series and Nexus ". Is that the end of the story? I see there is another type of flow control "priority flow control". Would that likely serve the the same purpose for Dell Compellent needs?
Looks like a lot of configuration. Any insight on this pairing is appreciated! However, if I connect SAN to extreme switches then we get less than 1ms latency and 10gbs of speed. That I believe is the compellent telling the Nexus to slow down that it can't handle what's coming at it. I've never run into this with any other SAN - e. Netapp nor Tegile.
Are they just using archaic Ethernet NICs? The idea there would be that something that's supposed to enhance performance is actually just causing a mess. I don't have access to our SAN. Do you have a thought on that? Turning off the pause frames on the Compellent which I don't think you can would be similar to to cutting the wire to the check engine light in your car Theory is they were allowing something they shouldn't have been and a true fix stopped something that was allowing it to work.

While I am able to recognize when scripting is the right tool for the job, I do not author PowerShell scripts on a regular basis. So how do I get started — what are the cmdlets? There are a few different ways to retrieve a list of cmdlets made available by a PowerShell snapin or module.
When executed, it returns a list of all the cmdlets provided by the VMware. Core snapin used to manage a vSphere environment via PowerShell. As of this writing in the 5. Those snapins are:. However, not all PowerShell snapins ship with a native shortcut to retrieve a list of their respective cmdlets. In these cases, use Get-Command. Now Get-Command by itself returns cmdlets for all snapins. For a snapin specific list, either of the following will work:. To retrieve a list of Dell Compellent cmdlets, use one of the following:.
Is there an easier and persistent method to retrieve cmdlets from a given snapin? Of course the shortcut function provided in the example above is specific to the Dell Compellent snapin but it should work for for any PowerShell snapin including the list of VMware snapins not included in Get-VICommand discussed at the top of the article.

Anytime a virtual disk moves, the SAN sees it as new writes and doesn't relinquish the original space. So if you do lots of SVMotion jobs or disk-based backups that create snapshots then delete them, this could be a serious problem!
I ended up installing vCenter Orchestrator and using scheduled workflows to automate the process. There's a few catches though, few things you have to do before creating workflows in Orchestrator:.
Disable SSH security warnings. If SSH is enabled, it will generate warnings on the summary tab of each host. These warnings can be suppressed. SSH Password Authentication. To allow for applications such as vCenter Orchestrator to have root or shell access to an ESXi host, Password Authentication must be enabled. This feature was designed to efficiently reclaim deleted space to meet continuing storage needs. ESXi 5. The actual space reclamation command is as follows. So to automate this, what you can do is create custom scheduled workflows in vCenter Orchestrator and run something like this:.
Don't be suprized if you see 25, KBps. This is normal however, and its not truely using that much. The physical host is just writing the balloon file as fast as it can to the datastore, then deleting it immediately. Dell compellent tool actually has a "reclaim" tool to get the space back which would have made ALL this hard work unncessary Also you said MOST storage vendors have a problem with reclaiming of space.
I worked on Netapp, and as many complaints that I had with Netapp, I didn't find Netapp lacking in space or configuration problems I think you did all of this on your own, which is fine, good learning opportunity, but if you had invovled Dell you would have found out very quickly where your problem was. GOD I hate arguing, especially in forums Who do you think I worked with over the course of 2 months to accomplish this?
Copilot Support Case Look it up. Call 'em.When it comes to networking Dell has two main series of switches. This is what you will see when you boot the switch for the first time:.
After some time BMP will time out. When prompted choose to save the configuration and proceed with reload. After the switch has rebooted check that the next boot is set to normal reload:. Force10 switches have two boot banks A: and B:. You will be prompted to save the configuration and reboot. SuppotAssist helps to automatically open Dell service tickets if there is a switch fault. You can enable SupportAssist by running the following commands and answering prompts:.
But STP can save you from consequences of a potential human error, such as port channel misconfiguration. Just make sure to not use the basic STP protocol, as it provides the slowest convergence. In every STP topology there is also a root switch, which by default is selected automatically.
Typically your core switch should be your root switch. To avoid dropped packets on 10Gb switch ports at times of potential heavy utilization it is also a best practice to as a minimum enable bi-directional Flow Control on the storage array ports. Keep in mind, that port channels are used either in one switch configurations or when two or more switches are stacked together. Which are similar to port channels, but have a slightly different syntax.
We will talk about VLT in much more detail in the following Force10 blogs. Interested to here your thoughts if have a different take on that.
In this blog post I want to discuss what distinguishes Dell Compellent from the aforementioned arrays when it comes to multipathing and failover. This may help you make right decisions when designing and installing a solution based on Dell Compellent in your production environment.
The grouping of target ports is vendor specific. This has to do with how ports on storage controllers are grouped. Compellent does not present LUNs through the non-owning controller. You can easily see that if you go to the LUN properties. Fault domains group front-end ports that are connected to the same Fibre Channel fabric or Ethernet network.
Ports that belong to the same fault domain can fail over to each other because they have the same connectivity. Either of the designs work fine, this is really is just a matter of preference. Which then redirects the traffic to the actual controller IPs. If you use one iSCSI subnet and hence one fault domain, when you have a port failure, Compellent will move the failed port to the other port on the same controller within the same fault domain. A distinction needs to be made between the physical and virtual ports here.
Because from the physical perspective you lose one physical link in both One Fault Domain and Two Fault Domains scenarios. This is the scenario which you have to be careful with. Compellent does not initiate a controller failover when all front-end ports on a controller fail.The wizard helps configure the Storage Center to make it ready for volume creation.

Contents Search.I am implementing my SC all flash array and have a discrepancy between what vmware and compellent sees as available space. I am using thick provisioned eager zero volumes per the best practices with compellent since it doesn't store the unused white space thin provisioned on the storage. So in theory I cannot use this space that is gained on the same datastore since vmware will not see this.
I guess I will create additional datastores so that I can over-provision and reuse this space. Is this what most people do? You're correct in your assumption. You create more volumes and over-provision space on the storage array. Then you use array-tools to alert you when storage requirements are growing towards the limit of what you can support. And have a plan for expansion. I thin provision in VMware as well to prevent having so many volumes.
Either way, you have to monitor your free space carefully. It is addressed in the best practices guide for VMware page 53 I'm not aware of a way to present back to VMware the actual free space. Thanks for this info.
In admin training they said to thick eager zero the storage since it uses the same amount of space as thin on the compellent side and it also saves on the SCSI reservations for new writes. It looks like over-provisioning the storage and creating new datastores volumes in compellent terms in VMware is the only way to utilize the space gained do to compression and dedupe.
I'm ok with this method but I just wanted to check and make sure that I am not missing something obvious. I cannot emphasize enough that you need to have a plan and budget for expansion. Of storage space as well as performance IOPS and latency. I have my entire environment moved over and I am only using 33 percent of the storage.
My iop requirement is also very low. I'm only using 11 of the 24 drive bays as well, so I should have room to grow. It's an all SSD flash array. To continue this discussion, please ask a new question.
