SRDF SRA and SRM Test Failover review

Occasionally I'll get a question from a customer or even employee about doing failover testing in SRM with our SRDF SRA. While I have this documented extensively in the TechBook (TB), and most who contact me have been trying to use it, perhaps it is the very detailed nature of it that makes it challenging...

vSphere Automatic UNMAP/XCOPY issue

******** Update 10-14 ******** VMware has formalized the fix I tested and it is set to be included in the next patch for vSphere 6.7 which I believe should come by the end of the year. If the issue is causing major problems in your environment, however, you could open an SR and request the... Continue Reading →

VSI 8.2

VSI 8.2 is now GA and brings a few features for the PowerMax/VMAX platform. The binary and documentation are available on the support site here.

PowerMax 5978.444.444

Today is general availability for the new PowerMaxOS release. As I've done for previous releases, I want to cover the features/improvements that have some relationship to VMware environments. I will be adding this information into my whitepapers and TechBooks over the course of perhaps the next month, but for now it will be available here... Continue Reading →

In addition to the requisite support for the new PowerMax release, the SRA has a couple of new features as well as new support.... Continue Reading →

SRDF/Metro online device expansion

With the new PowerMaxOS 5978.444.444 release, you can now expand SRDF/Metro devices, and thus the VMware datastores built on top of them, online. You may recall in our current release you can expand SRDF/Metro devices but it does require suspending access to the R2 by changing the RDF mode to synchronous. I wrote this up... Continue Reading →

VAAI statistics

One area of VMware/PowerMax integration that has frustrated customers since inception is the inability to get VAAI command information from the array. The VAAI paper mentions that there is a column available called "Extent Based Clone" which will display source or target depending on how the device is being used; but that has very limited...

VMworld vBrown Bag Presentation

Today at VMworld Scott Delandy (@scottdelandy) and I did a presentation on using VMware Cloud Foundation with PowerMax as a Workload Domain. This is a new capability VMware is offering so that customers are able to use existing infrastructure as part of their VCF environment. Since VMware's SDDC Manager cannot control the PowerMax, you instead... Continue Reading →

vVols, VVols, VVOLs or again vVols?

So which is the correct spelling of VMware's storage paradigm? If you said, "all of them?" it would be hard to fault you. VMware has gone through many iterations of the capitalization before landing on "VVols" for the past couple years anyway. Well it was too good to last and VMware is asking for another...
