EMC gets flashier, how the portfolio grows...

Yesterday saw EMC make some major flash architectural, portfolio, and roadmap announcements by way of introducing a new name for what was previously VFCache, and announcing ready for beta XtremIO product that is now marching toward a near term GA.

EMC gets into Server Vendor Knickers with ScaleIO Acquisition

EMC bought ScaleIO last week for an undisclosed price. What is EMC doing with flash in the server? Didn’t they already do a deal with Virident and others for PCIe flash products recently? And, of course, they have already announced the all-flash array, based on the XtremIO acquisition. How many flash products do they want to offer? And what is EMC’s Flash Division doing buying a product that works with both flash and HDDs? These are all good questions that deserve good answers. Here is the way I see it.

Flash storage vendors make lucrative acquisition targets

Solid-state storage is not only a hot discussion topic with IT administrators and CIOs; it's also been a hotbed of acquisitions in the last 24 months.

EMC PowerPath: Optimized IO Multipathing for All Flash Arrays

All-flash arrays are changing the datacenter for the better. No longer do we worry about IOPS bottlenecks from the array: all-flash arrays (AFA) can deliver a staggering amount of IOPs. AFAs with the ability to deliver hundreds of thousands of IOPs are not uncommon. The problem now, however, is how to get the IOPS from the array to the servers. We recently had a chance to see how well an AFA using EMC PowerPath driver works to eliminate this bottleneck—and we were blown away. Most comparisons with datacenter infrastructure show a 10-30% improvement in performance; but, the performance improvement that we saw with PowerPath was extraordinary.

Getting bits from an array to server is easy —very easy, in fact. The trick is getting the bits from a server to an array in an efficient manner when you have many virtual machines (VM) on multiple physical hosts that are transmitting the bits over a physical network with a virtual fabric overlay; this is much more difficult. Errors can get introduced and must be dealt with, the most efficient path must be obtained and established, re-evaluated and reestablished continually, and any misconfiguration can produce less than optimal performance. In some cases, this can cause outages or even data loss. In order to deal with the “pathing,” or how the I/O travels from the VM to storage, the OS running on the host needs a driver, or in the case where multiple paths can be taken from the server to the array, a multipathing driver needs to be used to direct the traffic.

Windows, Linux, VMware and most other modern operating systems include a basic multipath driver; however, these drivers tend to be generic and not code optimized to extract the maximum performance from an array and come with only rudimentary traffic optimization and management functions. In some cases these generic drivers are fine, but in the majority of datacenters the infrastructure is overtaxed and its equipment needs to be used in the most efficient manner possible. Fortunately, storage companies such as EMC are committed to making their arrays work as performant as possible and spend a considerable amount of time and research to develop multipathing drivers optimized for their arrays. EMC invited us to take a look at how PowerPath, their optimized “intelligent” multipath driver, performed on an XtremIO flash array connected to a Dell PowerEdge R710 server running ESXi 6.0 while simulating an Oracle workload. We looked at the results of the various tests EMC ran comparing PowerPath/VE multipath driver against VMware’s ESXi Native Multipath driver and we were impressed—very impressed—by the difference that an optimized, multipath driver like PowerPath can make in a high IO traffic scenario.

The evolution of flash-based storage arrays

Oracle and HP prove that it's just not a case of all-flash or hybrid when selecting a solid-state-enhanced array.

Arun's takeaways from EMC World 2016

Chad Sakacs said EMC will be #1 market share leader in HyperConvergence space by the end of 2016. Nutanix is, of course, the main target. VxRack 1000 announced to cover VMware, OpenStack and Cloud Native segments, using Flex, SDDC and Neutrino Nodes. I saw no signs of worry that these products will negatively affect existing SAN and NAS products. EMC doesn’t seem to care what product sells, as long as it is an EMC product; the customer is free to choose what fits the task. This attitude will serve it well in the infrastructure transition happening right now.

Enterprise SSDs: The Case for All-Flash Data Centers

Adding small amounts of flash as cache or dedicated storage is certainly a good way to accelerate a key application or two, but enterprises are increasingly adopting shared all-flash arrays to increase performance for every primary workload in the data center.
