Traffic Isolation Zoning – The mistake of FOS

Good post by Erwin van Londen (thank you)

If there is one thing I would consider “the” blunder of FOS engineering it has to be Traffic Isolation zoning. I mean, creating such an administrative nightmare with obscure directions causing confusion and nasty pitfalls when one thing goes wrong is in many occasions a recipe for disaster.

QLogic 16Gb Gen 5 FC Now Offered on EMC VNX Hybrid Flash Storage

Post by Pedro Hernandez (thank you)

Eyeing virtualized data centers, EMC and QLogic have teamed to move VNX arrays into the storage area network (SAN) fast lane.

EMC VNX hybrid flash storage arrays are now available with QLogic’s high-speed 16Gb Fiber Channel (FC) technology, the Aliso Viejo, Calif.-based provider of storage networking components and equipment announced today. VNX is EMC’s midrange line of flash-enabled, unified storage systems (NAS and SAN). The Hopkinton, Mass.-based data storage giant overhauled VNX in 2013, including enhancements to its underlying MCx software to improve flash integration.

SDS – The Missing Link – Storage Automation for Application Service Catalogs

Post by Rawlinson Rivera (thank you)

Automation technologies are a fundamental dependency to all aspects of the Software-Defined Data center. The use of automation technologies not only increases the overall productivity of the software-defined data center, but it can also accelerate the adoption of today’s modern operating models.

In recent years, a subset of the core pillars of the software-defined data center has experienced a great deal of improvements with the help of automation. The same can’t be said about storage. The lack management flexibility and capable automation frameworks have kept the storage infrastructures from delivering operational value and efficiencies similar to the ones available with the compute and network pillars.

VMware’s software-defined storage technologies and its storage policy-based management framework (SPBM) deliver the missing piece of the puzzle for storage infrastructure in the software-defined data center.

New X-IO ISE 800 All-Flash Array

Good post by Chris Mellor (thank you) over at El Reg

X-IO’s five-year warranty, maintenance-free sealed disk and disk+flash arrays have a new brother: the all-flash ISE. It’s sprinted right to the top of the SPC-1 price/performance benchmark charts.

The ISE 800 comes in a standard 3U X-IO enclosure and uses X-IO’s Gen 3 architecture, which first appeared in the ISE 780 in January. There are three models:

  • 820 – to 6.4TB pre-RAID capacity (2.7TB RAID 10, 4.3TB RAID 5)
  • 850 – to 25.6TB pre-RAID capacity (11.4TB RAID 10, 18.3TB RAID 5)
  • 860 – to 51.2TB pre-RAID capacity (22.9TB RAID 10, 36.6TB RAID 5)

All provide a max of 400,000 IOPS, or 260,000 IOPS with what is called an OLTP workload. There is up to 5GB/sec of bandwidth available.

Understanding Software Defined Storage

Very good post by Pushpesh Sharma (thank you)

Storage systems are essential to the data center. Given the exponential rate of data growth, it is increasingly becoming more and more challenging to scale the enterprise storage infrastructure in a cost effective way.

Storage technology over the years has seen incremental technology advancements. The early days of enterprise storage were mainly direct-attached storage (DAS) with host bus adapters (HBAs)  and redundant array of independent disks (RAIDs.) The DAS advanced by more faster and more reliable protocols like ATA over Ethernet(ATA), serial attached technology adapters (SATA), external serial attached technology adapters (eSATA), small computer system interface (SCSI), serial attached SCSI (SAS), and fibre channel.

EMC VNXe3200 Review

Good Review by the StorageReview Enterprise Lab (thank you)

The EMC VNXe3200 unified hybrid array brings VNX engineering, functionality, and enterprise support services to SMBs and ROBOs with a starting price of $11,500. That combination makes the VNXe3200 array accessible for customers that may have been priced out of the VNX lineup in the past. Unlike most other VNX offerings, the VNXe3200 uses a compact 2U form factor that integrates controllers and storage making it more suitable than prior VNX offerings for hub and spoke deployments like retail point-of-sale storage and offsite replication.

Microsoft’s Scale-Out File Server Overcomes SAN Cloud Barriers

Good post by Paul Schnackenburg (thank you)

There are no SANs in the cloud because the venerable storage technology just doesn’t scale to that level. But there are ways around it, and Microsoft shops should start with the company’s Scale-Out File Server.

There’s a revolution going on in storage. Once the domain of boring but dependable storage-area network (SAN) arrays, there’s now a plethora of choice, including all flash storage (with varying different underlying technology) and server-message block (SMB)-based storage.

Short stroking disk drives to improve performance

Good Post by Erwin van Londen (thank you)

Reading a post from Hans DeLeenheer (VEEAM) which ramped up quite a bit including responses from Calvin Zito (HP), Alex McDonald (NetApp) and Nigel Poulton. The discussion started on a comment that XIO had “special” firmware which improved IO performance. Immediately the term “short-stroking” came up which leads to believe X-IO is cheap-skating on their technologies. I was under the same impression at first right until the moment I saw that Richard Lary is (more or less) the head of tech at X-IO together with Clark Lubbers and Bill Pagano who also come out of that same stable.

VMware VVols is coming. Will your storage be ready for it? HP 3PAR StoreServ will be!

Good Post by Eric Siebert (thank you)

After more than three years in development, VMware Virtual Volumes (VVols) storage technology is set to ignite the storage array landscape. VMware VVols represents a major change in the vSphere storage architecture for shared storage arrays. It provides storage with VM-level granularity by introducing a 1:1 mapping of VMs to storage volumes as well as simplifies storage management through automated policy-based management. Prior to VVols, storage arrays primarily integrated with vSphere at a volume/datastore level using VMware’s Virtual Machine File System (VMFS). Moving forward, you can choose to use VMFS or VVols, with VVols offering more advanced capabilities as the preferred option.

Catching up on Fibre Channel with HP and Brocade

Good post by Calvin Zito (thank you)

One of the conversations I had at the recent Nth Symposium was with AJ Casamento from Brocade.  HP and Brocade have partnered in storage networking for a long time – probably about as long as AJ and I have worked in the industry!

Here’s a summary of what AJ and I discussed:

  • Looking deeper into the storage network stack with Fabric Vision
  • 16Gb Fibre Channel – ideal for low latency and all-flash
  • Optical infrastructure with Clearlink
  • When is the right time to look at Gen5 16Gb FC?
