More than an Exercise: Dell Compellent Storage Center and Five Nines Availability

Five nines availability is not restricted to the enterprise. Businesses of all sizes, from cost conscious mid-size to larger enterprises, frequently need five nines availability. At the same time they also require cost-effective CAPEX and OPEX. Dell has already stepped in to this market with the five nines Compellent Storage Center. Their test results are impressive and illustrate how seriously Dell takes the need for cost-effective yet highly available storage for businesses.

Making The Virtual Infrastructure Non-stop: And Making Availability Efficient with Symantec’s VCS

The past few years have seen virtualization rapidly move into the mainstream of the data center. Today, virtualization is often the defacto standard in the data center for deployment of any application or service. This includes important operational and business systems that are the lifeblood of the business.

For mission critical systems, customers necessarily demand a broader level of services than is common among the test and development environments where virtualization often gains its foothold in the data center. It goes almost without saying that topmost in customer’s minds are issues of availability.

Availability is a spectrum of technology that offers businesses many different levels of protection – from general recoverability to uninterruptable applications. At the most fundamental level, are mechanisms that protect the data and the server beneath applications. While in the past these mechanisms have often been hardware and secondary storage systems, VMware has steadily advanced the capabilities of their vSphere virtualization offering, and it includes a long list of features – vMotion, Storage vMotion, vSphere Replication, VMware vCenter Site Recovery Manager, vSphere High Availability, and vSphere Fault Tolerance. While clearly VMware is serious about the mission critical enterprise, each of these offerings have retained a VMware-specific orientation toward protecting the “compute instance”.

The challenge is that protecting a compute instance does not go far enough. It is the application that matters, and detecting VM failures may fall short of detecting and mitigating application failures.

With this in mind, Symantec has steadily advanced a range of solutions for enhancing availability protection in the virtual infrastructure. Today this includes ApplicationHA – developed in partnership with VMware – and their gold standard offering of Veritas Cluster Server (VCS) enhanced for the virtual infrastructure. We recently turned an eye toward how these solutions enhance virtual availability in a hands-on lab exercise, conducted remotely from Taneja Group Labs in Phoenix, AZ. Our conclusion: VCS is the only HA/DR solution that can monitor and recover applications on VMware that is fully compatible with typical vSphere management practices such as vMotion, Dynamic Resource Scheduler and Site Recovery Manager, and it can make a serious difference in the availability of important applications.

Edge HyperConvergence for Robo's: Riverbed SteelFusion Brings IT All Together

Hyperconvergence is one of the hottest IT trends going in to 2016. In a recent Taneja Group survey of senior enterprise IT folks we found that over 25% of organizations are looking to adopt hyperconvergence as their primary data center architecture. Yet the centralized enterprise datacenter may just be the tip of the iceberg when it comes to the vast opportunity for hyperconverged solutions. Where there are remote or branch office (ROBO) requirements demanding localized computing, some form of hyperconvergence would seem the ideal way to address the scale, distribution, protection and remote management challenges involved in putting IT infrastructure “out there” remotely and in large numbers.

However, most of today’s popular hyperconverged appliances were designed as data center infrastructure, converging data center IT resources like servers, storage, virtualization and networking into Lego™ like IT building blocks.  While these at first might seem ideal for ROBOs – the promise of dropping in “whole” modular appliances precludes any number of onsite integration and maintenance challenges, ROBOs have different and often more challenging requirements than a datacenter. A ROBO does not often come with trained IT staff or a protected datacenter environment. They are, by definition, located remotely across relatively unreliable networks. And they fan out to the thousands (or tens of thousands) of locations.

Certainly any amount of convergence simplifies infrastructure making easier to deploy and maintain. But in general popular hyperconvergence appliances haven’t been designed to be remotely managed en masse, don’t address unreliable networks, and converge storage locally and directly within themselves. Persisting data in the ROBO is a recipe leading to a myriad of ROBO data protection issues. In ROBO scenarios, the datacenter form of hyperconvergence is not significantly better than simple converged infrastructure (e.g. pre-configured rack or blades in a box).

Riverbed’s SteelFusion we feel has brought full hyperconvergence benefits to the ROBO edge of the organization. They’ve married their world-class WANO technologies, virtualization, and remote storage “projection” to create what we might call “Edge Hyperconvergence”. We see the edge hyperconverged SteelFusion as purposely designed for companies with any number of ROBO’s that each require local IT processing.

Full Database Protection Without the Full Backup Plan: Oracle's Cloud-Scaled Zero Data Loss Recovery

Today’s tidal wave of big data isn’t just made up of loose unstructured documents – huge data growth is happening everywhere including in high-value structured datasets kept in databases like Oracle Database 12c. This data is any company’s most valuable core data that powers most key business applications – and it’s growing fast! According to Oracle, in 5 years (by 2020) most enterprises expect 50x data growth. As their scope and coverage grow, these key databases inherently become even more critical to our businesses. At the same time, the sheer number of database-driven applications and users is also multiplying – and they increasingly need to be online, globally, 24 x 7. Which all leads to the big burning question: How can we possibly protect all this critical data, data we depend on more and more even as it grows, all the time?

We just can’t keep taking more time out of the 24-hour day for longer and larger database backups. The traditional batch window backup approach is already often beyond practical limits and its problems are only getting worse with data growth – missed backup windows, increased performance degradation, unavailability, fragility, risk and cost. It’s now time for a new data protection approach that can do away with the idea of batch window backups, yet still provide immediate backup copies to recover from failures, corruption, and other disasters.

Oracle has stepped up in a big way, and marshaling expertise and technologies from across their engineered systems portfolio, has developed a new Zero Data Loss Recovery Appliance. Note the very intentional name that is focused on total recoverability – the Recovery Appliance is definitely not just another backup target. This new appliance eliminates the pains and risks of the full database backup window approach completely through a highly engineered continuous data protection solution for Oracle databases. It is now possible to immediately recover any database to any point in time desired, as the Recovery Appliance provides “virtual” full backups on demand and can scale to protect thousands of databases and petabytes of capacity. In fact, it offloads backup processes from production database servers which can increase performance in Oracle environments typically by  25%. Adopting this new backup and recovery solution will actually give CPU cycles back to the business.

In this report, we’ll briefly review why conventional data protection approaches based on the backup window are fast becoming obsolete. Then we’ll look into how Oracle has designed the new Recovery Appliance to provide a unique approach to ensuring data protection in real-time, at scale, for thousands of databases and PBs of data. We’ll see how zero data loss, incremental forever backups, continuous validation, and other innovations have completely changed the game of database data protection. For the first time there is now a real and practical way to fully protect a global corporation’s databases—on-premise and in the cloud—even in the face of today’s tremendous big data growth.

5 9's Availability in a Lower Cost Dell SC4020 Product? Yes, Really!

Every year Dell measures the availability level of its Storage Center Series of products by analyzing the actual failure data in the field. For the past few years Dell has asked Taneja Group to audit the results to ensure that these systems were indeed meeting the celebrated 5 9s availability levels. And they have. This year Dell asked us to audit the results specifically on the relatively new model, SC4020.

Even though the SC4020 is a lower cost member of the SC family, it meets 5 9s criteria just like its bigger family members. Dell did not cut costs by sacrificing availability, but by space-saving design like a single enclosure for media and controllers instead of two separate enclosures. Even with the smaller footprint – 2U to the SC8000’s 6U -- the SC4020 still achieves 5 9s using the same strict test measurement criteria.

Frankly, many vendors choose not to subject their lower cost models to 5 9s testing. The vendor may not have put a lot of development dollars into the lower cost product in an effort to reduce cost and maintain profitability on a lower-priced system.

Dell didn’t do it this way with the SC4020. Instead of watering it down by stripping features, they architected high efficiency into a smaller footprint. The resulting array is smaller and more affordable, and retains the SC Series enterprise features: high availability and reliability, performance, centralized management, not only across all SC models but also across the Dell EqualLogic PS and FS models. This level of availability and efficiency makes the SC4020 an economical and highly efficient system for the mid-market and the distributed enterprise.
