Storage Networking

Storage Networking focuses upon virtualizing the storage and the SAN while collapsing and simplifying the management and performance of storage. This includes the role of storage virtualization in the Software Defined Data Center, and the comparison of pooled local storage options with traditional network attached storage (NAS) and fiber channel attached storage. Covered vendors include VMware, EMC, IBM, Dell, HP, Cisco, Tintri, and Nutanix.

News: Violin Memory Announces Concerto 7000 All-Flash Array

Violin Memory announces the Concerto 7000, which builds on its success with its 6000-series All-Flash Array (AFA). On top of Violin Memory’s proprietary all-flash hardware, this new model adds a comprehensive set of data services focused on business continuity, data protection, scaling, and efficiency.

The Concerto 7000 can now replicate to remote arrays either synchronously or asynchronously over Fibre Channel or IP-based WAN links with built-in WAN optimization. The 7000 also adds snapshot capabilities that enable new backup software integration and can be used as copy-on-write thin writable clones. Consistency groups, also a new feature, are an important but often overlooked way to keep multiple storage volumes in lockstep to guarantee application crash consistency in a disaster recovery/business continuity situation.

On the hardware side, Violin has improved the density of its all-flash array from 70 TB to 280 TB and can now pool capacity across separate storage units, or “shelves.” Customers can also have a single name space across shelves, making management of their arrays much easier. Finally, Violin adds online LUN and array capacity expansion, meaning no downtime to grow their offerings.

Violin and its customers claim massive savings by switching to these all-flash arrays. Not only are they much more power-efficient than traditional disk, but their incredible performance (500,000 sustained IOPS at 0.5 ms latency with a mixed workload) often means fewer servers are needed for a workload. In turn, that means fewer software licenses as well as compound savings for power, cooling, and overall data center space.

Current Violin Memory 6000 customers will be able to upgrade to the 7000 series through a predefined hardware upgrade path.

At its User Forum this week, Dell announced Dell Storage SC4020 availability in the United States. The SC4020 is a small- to mid-size Compellent Storage Center array running the same Storage Center 6.5 software as the SC8000 enterprise arrays, but with a smaller form factor and more limited scalability. The SC4020 has been available in APJ markets since earlier in 2014.  Continue reading News: Dell Storage SC4020 Announced in US Market

News: Oracle Buys GreenBytes — Once More on the Road to Obscurity

StorageNetworkingOn May 16, 2014, Oracle entered into an agreement to acquire GreenBytes, a provider of ZFS technology, for an undisclosed price. In addition to expertise in areas related to ZFS, GreenBytes has developed a deduplication, replication, and virtualization overlay for it. (Rather bizarrely, in a tussle with the then-giant in 2009, GreenBytes accused Sun of stealing its deduplication technology.)

Finding Atlantis USX—The Move to the Ocean from the Sea

Atlantis100x30Most will know Atlantis from the days of ILIO Persistent VDI and ILIO Diskless VDI. I would expect that most even consider it a niche product with the single goal of accelerating desktops. I have to admit, I was shocked to find that this is no longer the case. It is well known that I have been quite vocal in my thoughts about this company. People I know and trust have had bad things to say about its performance and stability. Admittedly, this is hearsay and also very old knowledge. But mud sticks. I also have to say I have undergone a road to Damascus moment regarding this company and its products. They have obviously improved on stability; further, the performance and functionality have gone stellar.  Continue reading Finding Atlantis USX—The Move to the Ocean from the Sea

Storm in a Teacup, or as Elmer FUD Would Say, “Shhh—be vewy vewy quiet; I’m hunting wabbits”

DataCenterVirtualizationWhat is it about the tech world that always seems to put us at each others’ throats? FUD is thrown around like candy from a broken piñata. Notable oppositions that come to mind are EMC vs. NetApp, block vs. file, diversity vs. simplicity, an so on. Currently, we have the software-defined networking (SDN) wars: hyper-converged vs. all-flash arrays (AFA). This was going to be a rant post, but Chad Sakac does that so much better than me. If you have a spare hour or so, have a read of his latest post; it makes for very good reading, and considering his role in the hierarchy of EMC, it is remarkably unbiased.
