IBM Power Systems Feature New I/O Enhancements

Two new PCIe Gen3 SAS adapters introduce the next generation of IBM SAS adapter technology to exploit the SSD flash technology evolution, a 12 GB write cache adapter and a zero write cache adapter. Both support twice as many SSDs as earlier PCIe Gen2 SAS adapters, provide more I/O operations per second (IOPS), and support greater throughput (MB/s).

 

The PCIe3 12 GB Cache RAID SAS Adapter (#EJ0L) supports up to 48 SSDs and up to 96 hard disk drives (HDDs). The new adapter also effectively offers up to over six times more write cache for greater write performance than the PCIe Gen2 features 5913 and ESA3.

 

The PCIe3 RAID SAS Adapter (#EJ0J) is a new zero write cache SAS adapter. It uses the same high-performance PCIe Gen3 technology as feature EJ0L but is a lower-cost option than the PCIe3 12 GB Cache RAID SAS Adapter while still providing better performance than delivered by the earlier PCIe Gen2 SAS adapter (#ESA1).

 

The PCIe3 SAS Tape Adapter (#EJ0X) supports the attachment of SAS LTO-5 and LTO-6 tape drives.

 

All of these PCIe Gen3 adapters are introduced on the Power 795 server.

 

Support for the refreshed PCIe Gen2 SAS adapter, which was originally announced for just four Power Systems models, is expanding to include more models. The PCIe2 1.8 GB Cache RAID SAS Adapter (#ESA3) is now supported across most of the Power 720, 730, 740, 750, 760, 770, and 780 servers and the PowerLinux™ 7R2 and 7R4 servers. Feature ESA3 offers lower cost and higher energy efficiency than the feature 5913 SAS adapter, with the same performance and function.

 

Two new PCIe binary synchronous adapters (#EN13/#EN14) are available for clients running IBM i on IBM POWER7 technology-based servers who still need binary synchronous capability. These adapters can be used instead of features 2893 and 2894, which are being withdrawn from marketing. Non-binary synchronous functions are available for IBM i 7.1 TR5 and TR7 through the lower-cost PCIe async adapter (#5289/#5290).

  • SB Profound WP 5539More than ever, there is a demand for IT to deliver innovation. Your IBM i has been an essential part of your business operations for years. However, your organization may struggle to maintain the current system and implement new projects. The thousands of customers we've worked with and surveyed state that expectations regarding the digital footprint and vision of the company are not aligned with the current IT environment.

  • SB HelpSystems ROBOT Generic IBM announced the E1080 servers using the latest Power10 processor in September 2021. The most powerful processor from IBM to date, Power10 is designed to handle the demands of doing business in today’s high-tech atmosphere, including running cloud applications, supporting big data, and managing AI workloads. But what does Power10 mean for your data center? In this recorded webinar, IBMers Dan Sundt and Dylan Boday join IBM Power Champion Tom Huntington for a discussion on why Power10 technology is the right strategic investment if you run IBM i, AIX, or Linux. In this action-packed hour, Tom will share trends from the IBM i and AIX user communities while Dan and Dylan dive into the tech specs for key hardware, including:

  • SB HelpSystems ROBOT GenericForms of ransomware has been around for over 30 years, and with more and more organizations suffering attacks each year, it continues to endure. What has made ransomware such a durable threat and what is the best way to combat it? In order to prevent ransomware, organizations must first understand how it works.

  • SB HelpSystems ROBOT GenericIT security is a top priority for businesses around the world, but most IBM i pros don’t know where to begin—and most cybersecurity experts don’t know IBM i. In this session, Robin Tatam explores the business impact of lax IBM i security, the top vulnerabilities putting IBM i at risk, and the steps you can take to protect your organization. If you’re looking to avoid unexpected downtime or corrupted data, you don’t want to miss this session.

  • SB HelpSystems ROBOT GenericCan you trust all of your users all of the time? A typical end user receives 16 malicious emails each month, but only 17 percent of these phishing campaigns are reported to IT. Once an attack is underway, most organizations won’t discover the breach until six months later. A staggering amount of damage can occur in that time. Despite these risks, 93 percent of organizations are leaving their IBM i systems vulnerable to cybercrime. In this on-demand webinar, IBM i security experts Robin Tatam and Sandi Moore will reveal:
