Major University Gives SIOS LifeKeeper for Linux Top Marks for Protecting Oracle

New York area university reduces TCO, boosts performance, and protects data availability in their Oracle environment.

When a leading university in New York decided to revamp its enterprise resource planning (ERP) system, it hoped to improve performance (especially during peak regis- tration periods) and reduce overall total cost of ownership (TCO). The university met these goals and gained unexpected benefits by moving their systems to Red Hat Linux on servers that were integrated with SanDisk Fusion ioMemory products and SIOS LifeKeeper for Linux.

Protection is Paramount

The university comprises multiple divisions that serve more than 10,000 students. Their use a mission-critical Oracle database to maintain all the information for student registration. They used an HP/UX, SAN- based storage environment with replication of its full SAN architecture between two fabrics in a cluster. It tracked costs associated with SAN storage for each fabric separately.

The university wanted an alternative that would be more cost-effective, deliver faster performance, and provide high availability and data protection for their mission-critical Oracle database.

Realizing that they needed a more robust clustering solution than they could get with a typical Linux solution, the university turned to Brian Roth of Comport Consulting for help.

“As I was researching, I found SIOS and knew it was the right solution,” says Roth. SIOS LifeKeeper for Linux provided application failover, SIOS DataKeeper provided data replication, and the SIOS Oracle Application Recovery Kit offered extra protection for
the school’s database right out of the box. Roth also noted that SIOS’ strategic alliance with Western Digital could deliver a high- performance SanDisk flash solution for their clustered environment.

“We wanted a suitable clustering replacement,” said the university’s Assistant Vice President
of IT. “SIOS explained that they could integrate and set up a cluster with SanDisk Fusion ioMemory products. They were completely proactive, which we appreciated.” The integration of ioMemory-based IO accelerators with both the servers and SIOS LifeKeeper

for Linux offered better performance and availability than traditional legacy solutions, making the SIOS product a perfect fit.

Goodbye to SAN Cost and Complexity

With servers configured with SanDisk Fusion ioMemory-based IO accelerators, the university could replace its bulky and expensive SAN-based setup with a streamlined server set running Linux. SIOS Protection Suite provided data replication and the SIOS application recovery kit protected the dedicated Oracle machines.

SIOS field engineering team worked with the university’s IT team via conference call to install and configure the cluster. “We have a very easy-to-use, wizard-based GUI that makes setup and configuration simple,” explained the SIOS Director of Sales Engineering. “No scripting experience is necessary. We often work with clients remotely to complete the installation and configuration,” he said. “You can be anywhere in the world and collaborate remotely with SIOS.”

The university’s team performed numerous stress tests using real data in a full test environment. The new systems’ ease of use, improved performance, and high availability were immediately apparent.

Reduced Costs, Reduced Risk

“Everything just worked,” said Roth. “And the cost of three servers and the SIOS solution was less than the cost of one of their old HP/ UX servers.” The university used the savings to add more memory.

The university also eliminated risk because the shared disks in a traditional SAN-based cluster can be a single point of failure. That’s why they originally had two SANs. SIOS replication with SanDisk Fusion ioMemory eliminated this single point of failure, costs far less than fabric switches and provides more data copies. And since the solution is simply two cards in the server, the university also saved on power, cooling, and data center floorspace.

Brian Roth noted that the combination of SanDisk’s flash-based Fusion ioMemory for storage and SIOS replication improved the school’s TCO, reduced data center costs, and reduced their environmental impact thanks to reduced power and cooling demands.

“Now we can perform seamless migrations without the high level of expertise needed to run a SAN,” Roth says.

Flawless Student Registration

The real test of the system came with the university’s busy spring registration session. From a technical perspective, the school enjoyed its most problem-free registration in 10 years. There were no calls to the IT help desk, and the registration ran flawlessly.

“Performance has been excellent,” said the school’s AVP of IT. “The few times we’ve had to speak with SIOS, the support has been excellent also. And they’ve been proactive in reaching out after go-live to make sure things were working properly.”

“This was my first time working with SIOS,” Roth said. “Working with the SIOS team made it easy. They were constantly reaching out, making sure things got done right. They stepped up and were engaged and proactive and knew their stuff. There was nothing we asked that they couldn’t answer. The university and I are very happy.”

SIOS Delivers High Availability for Large Financial Services Firm

SIOS Delivers High Availability for Large Financial Services Firm

SIOS Protection Suite for Linux Delivers HA/DR for Critical Securities Applications on Oracle Databases

One of the oldest financial services firms in China provides securities and futures brokerage as well as investment banking, asset management, private equity, alternative investments, and financial leasing services. It is listed on both the Shanghai and the Hong Kong Stock Exchanges. The firm has 343 branches (including 302 securities branches and 41 futures branches) spanning 30 provinces, municipalities, and autonomous regions in the Peoples Republic of China. They also operate across 14 countries including Shanghai, Hong Kong, New York, London, Tokyo and Singapore and have a stable customer base of approximately 18 million customers.

The Environment

The company relies on securities trading applications based on Oracle Database. running in a Red Hat Linux operating system environment. While the firm’s IT team was backing up these applications and database frequently, they could not recover operation quickly in the event of a failure or disaster.

The Challenge

The financial services firm wanted to implement high availability (99.99% uptime) and disaster recovery protection for their critical applications and the Oracle database they rely on.

The Evaluation

The firm’s IT team wanted a clustering solution that would ensure they could reliably meet their service level agreements (SLAs) for high availability as well as their stringent recovery time and recovery point objectives (RTO, RPO). It needed to be proven to provide HA in a Linux environment. They also wanted a solution that would reduce the complexity of clustering in an open-source environment.

The Solution

The firm created a two-node cluster on physical servers using SIOS Protection Suite for Linux clustering software. The SIOS clustering software monitors the entire application stack – network, storage, OS, and application. In the event of a failover, the software orchestrates the failover of application operation to the secondary node in the cluster. Application-aware modules in the SIOS Protection Suite
simplifies the complexity of configuring a cluster for Linux environments.

The Results

The firm has been using the SIOS Protection Suite for Linux clustering for many years and continually implements SIOS products in their environments. In that time, the firm has consistently met their availability SLAs. From its straightforward implementation to its reliable, easy-to-use management, the SIOS clustering software has met or exceeded their expectations.

SIOS Technology Helps Telcos Navigate the Complexities of High Availability

In today’s connected world, high availability is not only essential — it is considered a lifeline of society and the economy. No internet means no cloud. Just a few minutes of downtime can cost companies millions of dollars and damage customer relationships. While cloud computing, edge computing, and IoT present many opportunities, they are also challenging to navigate.

In this ongoing series about high availability (HA) and disaster recovery (DR) for various industries, Harry Aujla, EMEA Pre-Sales Director of SIOS Technology Corp., discusses the importance of high availability in the telecom sector. He points out the challenges telcos are currently facing with high availability and how SIOS Technology is helping.

Check out the whole interview above to learn more.

Key highlights from this video interview:

  • The telecom sector is unique because it has a direct impact on most aspects of our professional and personal lives. We live in an interconnected society, so even if critical communication services are down for just a few minutes, it can cause havoc and lead to millions of dollars in lost revenue.
  • Telecom is constantly innovating and evolving with technologies such as 5G rollouts and cloud computing. Maintaining uptime and having high availability remain critical for customer facing systems and backend systems.
  • Aujla discusses how software-defined systems and decentralization are solving some of the challenges telcos face, particularly when considering agility and reliability.
  • Continuity is essential in the telco market, particularly since they deal with infrastructure critical systems, which are often protected with a fault tolerance solution. Aujla tells us that that means telcos often have an SLA of 99.99% availability (or five minutes of downtime per year).
  • Software-defined systems have enabled telcos to embrace digital transformation into the cloud, and to leverage the cost and flexibility that comes with cloud computing.
  • For VoIP systems, the cloud platform provider will only provide high availability services to a certain level within the solution stack, and the responsibility of maintaining SLAs within the cloud falls on VoIP providers and customers. Aujla explains how this is addressed by high availability tools.
  • For telcos, billing systems are considered critical. If customers cannot view or pay their bills, it will cause disruption for all parties involved, potentially affecting revenue and customer satisfaction. SIOS aims to deliver application availability and 99.99% SLAs.
  • IoT is a key use case of cloud computing, with data-capturing devices constantly feeding back into a central brain. Aujla explains why it makes sense to leverage the flexibility and agility cloud platforms offer.
  • Endpoints of IoT devices typically do not need high availability, but rather the data itself. However, the volume of data being collected today presents numerous challenges on the underlying infrastructure in terms of servers, storage, and networking. Aujla explains how this is driving cloud consumption and edge computing.
  • Cloud providers are geared towards availability of the infrastructure itself rather than monitoring what is happening inside the cloud instance where the IoT-centric applications could be running. For this reason, Aujla feels that it is up to customers to take responsibility for their application availability in the cloud.
  • SIOS has the ability to cluster and monitor applications and databases in the cloud, and should it detect failures, it can failover to the next available node in the cluster. Aujla explains how this improves the overall high availability SLA for protected applications.
