Description

As we adapt to a new normal, the transformation of digital technologies continues to have a profound impact on creating and accelerating transformations of business activities, processes, competencies, and models. To succeed, businesses must embrace this digital transformation, adopt agile processes and new technologies to deliver new services and experiences that customers and clients demand. LinuxONE servers are designed to help enable cloud native development and deployment and achieve encryption everywhere. All of these together can help to provide the cloud you want with the privacy and security you need.

The new functions and features of LinuxONE III can help accelerate transformation while avoiding cloud security risks and complex migration challenges. With the 19-inch standard frame efficient design, the LinuxONE can easily coexist with other platforms in a cloud data centre. LinuxONE III can protect data and simplify compliance with its highly resilient, secure platform and has the power to optimize digital services delivery, accelerate business innovation, and ultimately improve the bottom line.

LinuxONE III LT1 and LinuxONE III LT2 are enhanced in several key areas.

Cyber resiliency

IBM Secure Execution for Linux

LinuxONE III is designed to protect against the impact of cyberattacks by ensuring isolation of workloads, protecting against insider and external attacks and ensuring continuous service by mitigating impacts of downtime. Confidential Computing is the industry movement around using technology to protect data in use. Secure Execution for Linux furthers the Confidential Computing agenda through the implementation of a TEE on the LinuxONE platforms. With TEE technology, users will be able to achieve higher levels of trust, isolation, and access control over their data assets compared to general-purpose software environments. As more companies move their on-premises workloads to public and private clouds, the need for a highly secure, multitenant hosting solution becomes necessary to ensure the confidentiality and integrity of each application and its data. The high-level benefits include:

Enhanced security at enterprise scale by isolating workloads
Access limited to privileged insiders, such as Kubernetes and hypervisor administrators
Assurance of data confidentiality and integrity

Prepaid token expiration

Beginning with LinuxONE III LT1 and LinuxONE III LT2, prepaid tokens for On/Off Capacity on Demand (On/Off CoD) will be available five years after the LICCC expiration date.

z/VM® virtualization technology

z/VM virtualization technology and its enablement for GDPS® and HyperSwap® allows customers to achieve the same HA/DR capabilities they are used for z/OS® workloads and IBM Storage for their underlying z/VM Guests, including Linux guests. Improved z/VM GDPS capability, as requested by our customers, is provided with Multiple Subchannel Set (MSS) Multi-Target Peer-To-Peer Remote Copy (MT PPRC) support new with z/VM 7.2. Further, with Centralized Service Management it will be easier for customers to maintain the z/VM Systems up-to-date and compliant with service enhancements, including security fixes, on a timely manner.

Encryption everywhere

CCA Advanced Encryption Standard (AES) ATM PIN® processing and key management enhancements

CCA continues to add functionality to enable client workloads. New industry standards drive workload enhancements. The AES algorithm is being adopted by the banking industry to replace Triple DES (TDES). Standards have been developed for AES key management and AES PIN encryption with ISO-4 format PIN blocks. CCA 7.2 completes support for ISO-4 format PIN blocks across CCA financial services. CCA has also added support for AES encryption of EMV secure messages, as well as EMV-specific PIN Change operations (TDES and AES). Similarly, support has been added for the ANSI X9.24-3 AES Derived Unique Key Per Transaction (DUKPT) standard. This standard defines AES methods for deriving various types of keys for one-time use and static, longer use. AES-DUKPT keys are usable with CCA financial services as well as format-preserving encryption (FPE). This will aid clients in complying with requirements from card brands and payment networks. Clients can also export AES DUKPT keys in ANSI TR-31 key blocks.

CCA data encryption enhancements

FPE is a set of algorithms used in banking to encrypt customer data without changing its format or length. These algorithms are defined in the ANSI X9.124 standard. Support has been added for three of the algorithms--FF1, FF2, and FF2.1--to use for data encryption, decryption, and translation. These features will be useful to clients whose partners build these algorithms into their devices, anyone wishing to retain format and length for encrypted data, or anyone building point-to-point encryption (P2PE) applications.

CCA public key cryptography enhancements

A new ECC curve has been added to CCA. The ECC curve secp256k1 is known as the bitcoin curve because it is used in bitcoin public key cryptography. This curve is popular because of its performance characteristics. In CCA, it is usable with the ECDSA digital signature algorithm and ECC Diffie-Hellman services. These services are used for generating and verifying digital signatures and to support protocols for exchanging cryptographic keys with partners.

Cloud crypto enhancements for EP11

Cloud Hyper Protect Crypto Services is a key management and cloud hardware security module (HSM). It is designed to enable clients to take control of their cloud data encryption keys and cloud hardware security modules (IBM Crypto Express7S) loaded with the EP11 API.

For version 4.7.22, and higher, EP11 is adding re-encrypt support. This support allows for re-encrypting data within the HSM boundary for selected algorithms and modes that support independent encryption and decryption of blocks.

Domain Import/Export has been added. It allows for exporting and importing wrapping keys (WKs) and state of a domain without requiring the assistance of card administrators. This is helpful for cloud clients who prefer that the IBM cloud provider not be required to assist them with managing their crypto domains.

Do-not-Disturb mode has been added. This feature is strongly related to the Domain Import/Export feature. With this feature, domains can be configured such that card administrators are no longer allowed to manage a domain, except for zeroizing it. This assures clients that the IBM cloud provider will not be able to modify or extract any information from their crypto domain once it has been set up.

Expanded cryptography enhancements for the Hyper Protect Digital Assets platform

For EP11 versions 4.7.2, and higher, support has been added for BIP0032. BIP stands for Bitcoin Improvement Proposal. BIP0032 is referred to as a Hierarchical Deterministic Wallet standard, allowing clients to split their digital purse into multiple parts and give interested parties access to those parts of their purse. EP11 implements the special key derivation functions required for BIP0032.

Also, previously in EP11 versions greater than 3.6.15, support was added for the Edwards-curve Digital Signature Algorithm for smaller keys and signatures to drive greater security and speed for the signing and verification used in digital assets transactions.

z/VM virtualization technology

z/VM virtualization technology has always been very proactive, helping customers to harden their systems, with a virtualization layer compliant with standard certifications needed by our most demanding customers. IBM is pursuing Common Criteria Certifications (EAL 4+ and NIAP Virtualization Protection Profile) and FIPS 140-2 for z/VM 7.2. With encryption, z/VM enables guests to exploit and benefit from HW HSMs (Crypto Express® adapters) and virtual crypto devices which can be tailored to workload requirements.

Flexible compute

Coupling link support for LinuxONE III to participate in a Server Time Protocol Coordinated Timing Network (STP CTN)

On LinuxONE machines today, Server Time Protocol (STP) can connect to a Network Time Protocol (NTP), NTP/Pulse Per Second (NTP/PPS), Precision Time Protocol (PTP), or PTP/Pulse Per Second (PTP/PPS) external primary time reference. However, clients with LinuxONE machines that have Linux on Z operating system images running on them can't synchronize time with their IBM Z® CPCs running z/OS in a Parallel Sysplex®. This is due to the inability of the STP CTN to be extended to LinuxONE stemming from the lack of support for coupling links on LinuxONE.

This current support limits time synchronisation accuracy to Universal Coordinated Time (UTC) for LinuxONE, as there is no way to provide the high accuracy time synchronisation to the z/OS systems in the STP CTN. This limits clients' capability to achieve compliance with the latest government regulations for time synchronisation accuracy to UTC across all systems participating in financial trading systems.

By providing support for coupling links on LinuxONE, they can now join and participate in an STP CTN alongside the client z/OS systems in one or more sysplexes. This will enable clients to take advantage of the inherent accuracy of STP CTNs on their LinuxONE, improving their time synchronisation accuracy to UTC and comply with the latest regulations.

The coupling links need to be configured from a z/OS machine, so the support is currently limited to networks that include a z/OS sysplex machine connected to LinuxONE not running in DPM mode.

NVMe boot and IBM Dynamic Partition Manager (DPM) support

IBM is committed to continue to grow our NVMe footprint and continues to invest in our NVMe roadmap. To that end, initial program load boot support from IBM NVMe devices is now available on LinuxONE systems. Clients can now have boost support that runs solely on NVMe devices. Open raid software solutions that support NVMe devices can also be used with NVMe devices. In addition, clients can enjoy complete DPM support for NVMe devices. Clients can now use NVMe as storage devices on IBM Z in their DPM/cloud environment.

8U Reserved Space (#0150) hardware configuration flexibility (LinuxONE III LT2)

For clients utilizing single-phase power and fewer than 3 PCIe+ drawers, there is an option to hold 8U Reserved Space (#0150) in the LinuxONE III LT2 rack. This 8U of space in the frame can be populated by a client with up to two IBM FlashSystem® 9200 Models 9846-AG8 or 9848-AG8, or up to two IBM FlashSystems 7200 Model 2076-824, along with up to two IBM Storage Networking SAN32C-6 Fabric Switches, in order to reduce the physical footprint in the data centre. When the 8U Reserved Space feature is ordered, the LinuxONE III LT2 order will provide additional power ports in redundant power distribution units (PDUs), along with weight ballast and air flow filters as appropriate. Note that IBM would first complete installation of the LinuxONE III LT2 and turn it over to client operation, and then the storage can be added if the 8U Reserved Space has been ordered. This new hardware configuration flexibility feature is perfect for clients who fit into smaller I/O configurations and need the additional ease of a single-footprint approach.

16U Reserved Space (#0151) hardware configuration flexibility LinuxONE III LT2)

For clients utilizing single-phase power and fewer than 3 PCIe+ drawers, there is an option to hold 16U Reserved Space (#0151) in the LinuxONE III LT2 rack. This 16U of space in the frame can be populated by a client with IBM DS8910F Model 993. storage in order to reduce the physical footprint in the data centre. When the 16U Reserved Space feature is ordered, the LinuxONE III LT2 order will provide additional power ports in redundant PDUs, along with weight ballast and air flow filters as appropriate. Note that IBM would first complete installation of the LinuxONE III LT2 and turn it over to client operation, and then the storage can be added if the 16U Reserved Space has been ordered. This new hardware configuration flexibility feature is perfect for clients who fit into smaller I/O configurations and need the additional ease of a single-footprint approach.

z/VM virtualization technology

z/VM virtualization technology has always been about driving more agility and better TCO through virtualization without compromising security or scalability. With z/VM 7.2, IBM continues to offer clients a choice to obtain new enhancements through z/VM Continuous Delivery and features already available, like support for 80 Logical Processor, VSwitch Priority Queueing, and Dynamic Crypto, reinforcing the flexibility clients demand. Adding to existing flexibility, through Centralized Service Management, brings agility to the next level.
