StorageVIEW from VKernel – Part II


In StorageVIEW from VKernel – Part I I introduced you to VKernel StorageVIEW, a free tool which provides you with latency information as indicator of problem with host/datastore pair connected through FC, iSCSI and also NFS for up to five host to datastore links with the greatest latency. That being said let’s have a look at what’s under the hood and how this tool notified me a bottleneck in my home lab I just wasn’t aware of…till now, but now the video!

So as you can see on the video, I used to have (very) high latency with the local datastore of two of my ESXi hosts. A bit of background history here is necessary. Before I bought an Intel SSD X25-M G2 160GB to upgrade my home lab I used to run a couple of my nested ESXi’s on a Lexar 16GB ExpressCard SSD. I did not pay a lot, actually it was a real bargain at my local computer shop but it is also a crappy piece of hardware especially for write operations… I guess you get what you paid for 😦

Anyway, a few hours later after I’ve installed the VKernel StorageVIEW I started to get alerts. Those datastores were not being used to store VMs but nevertheless I decided to move those two nested ESXi’s to my QNAP storage device and since then no more StorageVIEW alerts. Thank you VKernel, I’m a happy man now 🙂

By the way I’m selling a Lexar 16GB ExpressCard SSD, very cheap, anyone interested?

    Hi Sebastian and thx for commenting.
    Yes I’ve noticed that and unfortunately YouTube tells you about the content issue after the video editing is finalized and uploaded to their servers 😦

    I’ll upload a version without background music for my German readers as soon as I can.

    Cheers,
    Didier

The shift in purpose, together with elevated usability and total high quality by fashion of respect to earlier tablets, was perceived as defining a company new class of consumer machine[7] and formed the industrial marketplace for tablets in the following year. The time period may additionally apply to a wide range of form elements that differ in position of the display by aspect of respect to a keyboard. The standard form is named slate, which doesn’t obtain an integrated keyboard but could also be connected to at least one by mode of a wireless link or a USB port.

Hybrids possess a removable keyboard in order that the contact display can be used as a stand-alone tablet. Booklets embrace two contact screens, and can be utilized as a notebook by displaying a digital keyboard in one among them.
