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.

Cohesity Data Platform: Hyperconverged Secondary Storage

Primary storage is often defined as storage hosting mission-critical applications with tight SLAs, requiring high performance.  Secondary storage is where everything else typically ends up and, unfortunately, data stored there tends to accumulate without much oversight.  Most of the improvements within the overall storage space, most recently driven by the move to hyperconverged infrastructure, have flowed into primary storage.  By shifting the focus from individual hardware components to commoditized, clustered and virtualized storage, hyperconvergence has provided a highly-available virtual platform to run applications on, which has allowed IT to shift their focus from managing individual hardware components and onto running business applications, increasing productivity and reducing costs. 

Companies adopting this new class of products certainly enjoyed the benefits, but were still nagged by a set of problems that it didn’t address in a complete fashion.  On the secondary storage side of things, they were still left dealing with too many separate use cases with their own point solutions.  This led to too many products to manage, too much duplication and too much waste.  In truth, many hyperconvergence vendors have done a reasonable job at addressing primary storage use cases, , on their platforms, but there’s still more to be done there and more secondary storage use cases to address.

Now, however, a new category of storage has emerged. Hyperconverged Secondary Storage brings the same sort of distributed, scale-out file system to secondary storage that hyperconvergence brought to primary storage.  But, given the disparate use cases that are embedded in secondary storage and the massive amount of data that resides there, it’s an equally big problem to solve and it had to go further than just abstracting and scaling the underlying physical storage devices.  True Hyperconverged Secondary Storage also integrates the key secondary storage workflows - Data Protection, DR, Analytics and Test/Dev - as well as providing global deduplication for overall file storage efficiency, file indexing and searching services for more efficient storage management and hooks into the cloud for efficient archiving. 

Cohesity has taken this challenge head-on.

Before delving into the Cohesity Data Platform, the subject of this profile and one of the pioneering offerings in this new category, we’ll take a quick look at the state of secondary storage today and note how current products haven’t completely addressed these existing secondary storage problems, creating an opening for new competitors to step in.
