At the SunTUG Sunshine Summit in Tampa, attendees enjoyed our presentation, HPE Shadowbase Synchronous Replication Feature Rollout, announcing HPE Shadowbase Zero Data Loss (ZDL). Data loss as a result of an unplanned outage is a thing of the past with this new release. We discussed major new HPE Shadowbase features, including:
Gravic recently published a new case study, A Large Financial Institution Migrates Datacenters with No Downtime Using HPE Shadowbase ZDM. A major financial company offers person-to-person money transfers, money orders, and business payments. The company implemented an active/active system with two NonStop systems located 1,000 miles apart, and the databases were synchronized with a legacy bi-directional data replication solution. When the company decided to move its systems to other cities, upgrading them in the process, it could not tolerate an application outage during the move, so it relied on HPE Shadowbase Zero Downtime Migration (ZDM) software to avoid application downtime and provide full business continuity protection while the move took place. Its customers were able to make money transfers and use all applications as the servers and services were relocated. The company also relied on HPE Shadowbase ZDM to replace its legacy data replication software product and position itself for continuous availability into the future.
The February issue of the NonStop Insider published the article, Gravic turns up the temperature on synchronous replication. "Let’s talk about something that is hot, really hot! Sizzling hot! From the time Gravic first began talking about Sizzling-Hot-Takeover (SZT) Replication Systems it caught our attention. In presentations given by Gravic it is hard to miss the presence of SZT, occupying a place between Active/Passive and Active/Active replication, and for good reason. Now you can configure your Disaster/Recovery (DR) environment to have some of the benefits of what Active/Active configurations provide without embracing a full-blown Active/Active configuration. Turns out, running applications on the passive system is no longer out of the question."
Part 1 covers MTTF — Mean Time To Failure while Part 2 focuses on Mitigating Redundant Failures via System Staggering. The reliability of a redundant system is optimized by minimizing the probability that both systems will fail simultaneously. If they both have the same failure probability distribution, then when one system is most likely to fail, so is the other system. Previous methods for calculating estimated availability from any point in time are flawed because they are based on memoryless random variables. The calculation of the average time to the next failure is always the same, regardless of how long a system has been in service. By staggering the system starting times so that their probability distributions are not aligned, the time that the two systems are most likely to fail are different. When one system is most likely to fail, the probability that the other system will fail is significantly reduced. Therefore, the probability of a dual system failure is reduced. Redundant system reliability can be greatly enhanced by staggering the starting times of the two systems. This strategy applies both to hardware failures and to software failures.
Gravic personnel enjoyed the 2016 Connect HPE NonStop TBC in San Jose, CA, and thank Connect and the HPE staff for hosting such a terrific gathering. At the Gravic Partner Technical Update, held prior to the TBC, we met with the HPE field teams, and hope to replicate that experience at 2017 events held around the world. We delivered several presentations, two with Mark Pollans of HPE, one on our synchronous replication feature rollout, one on a case study, and one on new availability topics with Dr. Highleyman of the Availability Digest. All are listed below:
Gravic, an HPE Silver Partner, was recently verified by HPE as tested on these two types of servers; HPE generated two posters for this announcement.

Gravic presented at the CTUG Fall Conference Fall Conference and the NENUG Fall Meeting, both held at HPE Headquarters, in Mississauga, Ontario and Andover, MA respectively. We congratulate each organization for creating a powerful forum for customers, partners, and HPE executives to share success stories and best practices, learn about each other’s latest offerings and future technology, and network with one another. It takes a special effort to do all of the planning and preparation for these meetings, and we heartily thank these organizations and the attendees that support them for creating such a valuable experience. At both shows, we presented on Improving Uptime and Eliminating Risk for Disruptive Migrations with HPE Shadowbase Zero Downtime Migration (ZDM) Technology.

Congratulations to Emile Roach of Scotiabank and Jere Douglas of CGI for winning our Sennheiser headphones gifts!
Gravic presented on HPE Shadowbase Zero Downtime Migration (ZDM) Technology at the well-attended ATUG (Atlanta Tandem User Group) Meeting at the Home Depot Headquarters in Atlanta, Georgia, USA. Special thanks to Marty Edelman and his staff for hosting the meeting, to Dale Van Stratten of XYPRO for his effort in organizing it, to HPE corporate for sending the NonStop A-team to support the rebirth of ATUG, and to the many customers that attended from the local NonStop user community. ATUG was originally established in the 1980’s and is now reformed with new purpose and comprised of members from HPE, partners, users and international vendors. Congratulations to Rob Chandley of VISA for winning our Sennheiser headphones gift!
Gravic presented at the first-ever Greater New York/New Jersey Area HPE & Partner NonStop Information Day, held for partners and users at the HPE Offices in Berkeley Heights, NJ. Our presentation on Shadowbase ZDM demonstrated how customers are leveraging HPE Shadowbase solutions to perform zero downtime migrations, and to safely eliminate planned downtime with no loss of business services for otherwise risky and disruptive application, database, and operating system upgrades. Several use case scenarios were reviewed for both homogeneous and heterogeneous migrations. If you are interested in discussing this presentation’s content or would like us to present this or other HPE Shadowbase topics to your staff, please contact us.
The conference was held at the beautiful Ranas Slott Castle outside of Stockholm, Sweden. The VNUG show is a very special event that fully engages the customers with great content and HPE and vendor support, while providing a refreshing atmosphere for networking. Each time we attend the conference, we are thankful for the hospitality that we receive from the VNUG board, customers, users, and HPE attendees. Paul J. Holenstein, Gravic EVP, presented on Improving Uptime and Eliminating Risk for Disruptive Migrations with HPE Shadowbase Zero Downtime Migration (ZDM) Technology. Congratulations to Thomas Monell of Evry Card for winning our GoPro Hero camera!
Gravic recently published a new White Paper, Hardware vs Software Data Replication for Business Continuity. Data replication is an enabling technology for achieving high or continuous availability for application services and the timely backup of important data. There are two primary data replication technologies, hardware replication and software replication. In this paper, these two technologies are compared, concluding that a business continuity architecture built on software-based transactional data replication is the only viable solution to meet the highest levels of service availability and protection against data loss for mission-critical applications.
Gravic Publishes New Article on Leveraging a Big Data Analytics Engine for Meaningful Insights. The cover article for the Summer issue of Connect Converge. This article looks at several cooperative technologies that extract valuable business information from the noise of big data, enabling businesses to obtain real-time business intelligence (RTBI), and the role that Shadowbase data replication software plays in a big data analytics engine.
Gravic publishes a new solution brief on Shadowbase Data Protection. Whether data is at rest or in motion, Shadowbase replication encryption provides protection against data theft. See how to take advantage of Shadowbase replication solutions for business continuity, data and application integration, real-time business intelligence, without compromising data security.
Gravic attended the BITUG BIG SIG Conference held in London and presented: Reducing Downtime and Eliminating Risk for Disruptive Migrations with HPE Shadowbase Zero Downtime Migration (ZDM) Technology. If you are interested in discussing this presentation’s content or would like us to present it to your staff, please contact us. Congratulations to Peter Frost of Euroclear who won our GoPro Hero camera prize! In preparation for hosting the 2017 European User Group (ETUG) Conference in the United Kingdom next May, BITUG promoters gave vendors and participants a sneak preview of the 2017 “EBITUG” agenda and venue, estimating that there will be 12 to 15 booths. (In recent years, ETUG was hosted by GTUG, the German User Group.)
The new format for the meetings was ideal at the recent MENUG Meetings that were held in Doha, Qatar and Dubai, UAE. In the mornings, the local and regional HPE teams presented their hardware and software roadmaps, followed by a brief break, and then each vendor gave a ten minute company introduction. Our introduction topic discussed Reducing Downtime and Eliminating Risk for Disruptive Migrations with HPE Shadowbase Zero Downtime Migration (ZDM) Technology. (If you are interested in discussing our presentation’s content or having us present it to you, please contact us.) The afternoons consisted of lunch and “speed dating,” where each vendor was allotted 20-30 minutes for one-on-one time with each customer, and ended when an alarm rang and the customers switched vendors.
Gravic published a new Products website section on Industry Services, highlighting three market segments Telecommunication Services, Transportation/Other Services, and Financial Services, with additional drill-down for Payment Services. Shadowbase software is used across a wide variety of industries for business continuity and data and application integration, delivering high IT service availability and distribution of data for real-time business intelligence and other purposes. We hope that you enjoy visiting this new section!
