Raidix ERA 3.4 with write holes protection

On November 15, 2021, Raidix announced the release of the updated release of the super-fast RAIDIX ERA software module for DSS.

It provides write holes protection, monitors read-write errors, and supports DM Multipathing.

This release has features that will have a beneficial effect on the fault tolerance and performance of software-defined DSS on flash drives.

Write hole - A situation where the data or checksums on RAID are non-consistent and this non-consistency is not detected by the system. In this case, a RAID disk failure may result in data loss. This can occur during asynchronous writing to a syndromic RAID (e.g. RAID 5, RAID 6, RAID 50, etc.), in the event of an abnormal situation (most commonly a power failure).

Now RAIDIX ERA protects data from loss due to write hole by starting checksum recalculation after a system failure, thereby eliminating inconsistency. The function is called resync and is enabled by default on all RAIDs on which write hole is possible.

The more disks in the system, the higher the likelihood that the drive will fail and possible DSS failure will occur. RAIDIX ERA 3.4 detects disks with accumulated errors and sends notifications to the user by mail or through the interface so that the administrator can replace damaged drives in a timely manner. In addition, in RAIDIX ERA 3.4, you can configure automatic disk replacement.

Users have the opportunity to use NVMe devices available in several ways - thanks to the support of DM Multipathing. This feature optimizes load balancing and improves system resiliency.

In addition, the evolution of Linux is taken into account when developing the product in RAIDIX. RAIDIX ERA 3.4 demonstrates full performance on distributions with the latest cores.

Using the Updated Data Redistribution Method

RAIDIX has patented a way to redistribute data when expanding the disk array and announced this on May 21, 2021.

This scaling approach enables you to achieve high DSS performance. The method is already implemented in RAIDIX ERA 3.2 and will be used in RAIDIX 5.1.

The approach characterizes:

• High rate of change in the level RAID of the mass without stopping the user load
• The ability to save data and progress RAID level changes after a system failure
• The ability to change the priority of data redistribution and user load.

{{quote "Thanks to this functionality, the problem of horizontal scaling and changing the RAID level" on the fly "is solved, while the priority between the client load and the operation of this service can be adjusted by the user himself, - comments Svetlana Lazareva, technical director of" RAIDIX. " }}

As of May 2021, the solution is already used to create high-performance DSS in corporate IT infrastructures, HPC computing and the media industry.

Raidix ERA 3.2 with support for more operating systems and applications

Support for NVMe Ultrastar SSDs from Westeren Digital

On December 8, 2020, the company Western Digital announced the beginning of a partnership with a RAIDIX development company () software ON to DSS maximize the potential of its Non-Volatile Memory Express (NVMe) storage devices when used in RAID mass. NVMe RAID with PO RAIDIX provides up to 10 million IOPs with 20 drives, while supporting a wide range of RAID levels to improve performance and protect data integrity.

Partnering with RAIDIX is a positive step for enterprise customers and will help both integrators and cloud service companies transition from Serial ATA (SATA) storage to faster NVMe-enabled solutions with significantly higher performance and lower latency.

NVMe SSDs provide high speed, but all enterprise systems also have increased data protection requirements for storage devices. In this case, to implement RAID functionality, you need a fail-safe array with minimal performance degradation.

By installing ERA software from RAIDIX, users can easily implement RAID software capabilities on Western Digital's NVMe Ultrastar SSDs. This will allow them to simultaneously protect data and maximize the performance potential of NVMe devices, avoiding unnecessary bottlenecks between the central processor (CPU) and DSS.

According to forecasts of the industry analytical company IDC, by 2023 the share of shipped NVMe SSDs will exceed 79% of the entire market. By directing processing data to multi-core vector registers, the RAIDIX solution for NVMe-enabled RAID provides fast checksum calculations to avoid system performance degradation at high load and in array recovery mode. In a general sense, it helps companies scale their infrastructure to meet peak needs with solutions such as intelligent business analytics, data analytics, virtualization, and IMS, and gives peace of mind thanks to its high reliability. Owners of Western Digital drives with NVMe support will be able to get PO RAIDIX for free for eight Western Digital devices.

As we consistently strive to offer our customers the best data-intensive solutions, the ability to maximize the potential of our NVMe-enabled Ultrastar SSDs plays a critical role for us. We are constantly looking for new ways to improve the performance of our storage solutions and the level of data reliability, and the announced partnership with RAIDIX is another step along the way. Legacy storage solutions on SATA are not the best way to work in the usual conditions for enterprise-class customers in the widespread distribution of data and cloud storage. As part of this partnership, customers will get a cost-effective and reliable RAID solution to migrate their DSS from SATA to the high-speed NVMe specification. - said the director of business development of Western Digital in the Europe, Middle East, Africa and India region (EMEAI) David Villa

Promising technologies, such as the Internet of Things () IoT and, 5G are forcing companies to face constant data growth, in this context, the scalability and efficiency of DSS especially important, and an optimized NVMe solution allows you to perfectly meet these needs. We are enthusiastically partnering with Western Digital and are ready to offer our customers high-performance RAID solutions that leverage both our software and the products of one of the industry's most trusted and respected drive manufacturers. SSDs with NVMe support are still not widely used, especially when it comes to networked DSS. We are confident that with our RAID software, companies will be able to quickly and smoothly transition to high-performance NVMe RAID solutions for DSS that meet modern data requirements. - added RAIDIX Vice President of International Sales Sergey Fedorov

Raidix ERA 3.1 with enhanced RAID stability and performance

On August 12, 2020, the company Raidix announced the release of ERA 3.1. It significantly improved the operation on high-load systems, databases increased the stability and performance RAID of -masses. To test the capabilities ON , a number of tests were carried out at the research laboratory of Boston Limited, a supplier of hardware components from the world's leading manufacturers. Test results showed more than 10 million IOps per RAID. The test system included 20 drives from Ultrastar DC SN640 Western Digital in polling mode, io_uring, IO interface Linux , platform and Xeon Supermicro Intel Gold 6240 CPU. Additional configuration increased RAID performance at low-depth loads by 3 times: 1 million IOps is achieved at a queue depth of only 4 requests at extremely low delays.

ERA 3.1 supports additional levels of arrays: RAID 10, 50, 60, and 70. They are recommended for large installations using more than 16 drives, which are especially effective, including in large media projects related to the production and delivery of content.

To improve the stability of RAID arrays, the partial reconstruction mechanism has been improved. It allows you to handle simultaneous multiple failures on drives by using separate reconstruction cards, while keeping the RAID array online. The mechanism for importing RAID arrays, which is used to combine several ERA RAID systems into one, has been improved.

The import mechanism and partial reconstruction technology will be as useful as possible in disaggregated data centers, in which drives connect to servers through a high-performance network and there is a high degree of "movement" of resources between applications, - comments Sergey Platonov, Deputy General Director of RAIDIX for Strategy.

Tracking the operation of the system has become easier: information about events that occur with RAID arrays can be received by mail using the notification service. The status of the drives can now be monitored using LED indication.

RAIDIX partners use the ERA software module to create high-performance solutions around the world. ERA 3.1 is also used in the latest release of PO RAIDIX 5.X, where it controls the operation of solid-state drives. Development continues on the next release of ERA 3.2, scheduled for release in the fourth quarter of 2020.

Raidix ERA 3.0

RAIDIX ERA 3.0 will allow you to combine flash devices into striped RAID arrays (RAID 10, 50, 60, 70), which provide greater performance on various load patterns. With an improved partial reconstruction mechanism, RAID arrays are more resistant to single I/O errors.

This release also introduced a system of mail alerts when changes in the operation of RAID arrays. Controlling the light indication on the drives themselves will allow you to determine their state (online/offline) and respond to changes in a timely manner.

The read and write speeds that RAIDIX ERA can achieve exceed 35 GBps and 4,500,000 IOPS per Level 6 RAID group, including during failures and restores. The technology is used to create storage systems where performance is essential: in the field of HPC, for IoT, VR/AR, working with highly loaded clusters of relational and NoSQL databases.

The use of RAIDIX ERA instead of traditional hardware RAID controllers provides an increase in the speed of server equipment and simplifies its use.

Synergy with Intel Optane

On September 6, 2019, RAIDIX announced that sharing just 4 Intel Optane drives with RAIDIX ERA, a software RAID, can achieve 1 million I/O requests under mixed read/write load. Comparison with solutions on NVMe SSD tests show high performance values ​ ​ even when using fewer drives, the company said.

Intel Optane drives are optimal for storing data near computing power for fast access, while RAIDIX ERA technology provides fast data access for both sequential and random loads. Compared to classic NAND SSDs, Intel Optane has Intel 3D XPoint memory architecture, which the manufacturer claims provides more stable performance of up to 431% on writes and up to 30% on reads.

RAIDIX ERA algorithms are designed to optimally leverage CPU capabilities by optimizing multithreaded computing. This is especially in demand in industries where ultra-fast access to large amounts of data is needed: the Internet of Things (IoT), virtual and augmented reality ( VR, AR), real-time trading (RTB), working with high-load databases (SQL/NoSQL), intensive computing in the field of HPC, processing video materials in 4K and 8K resolution.

RAIDIX ERA aggregates directly connected SSDs into fast virtual RAID, which is used in resource-intensive applications. The main principle of the technology is to optimize computing for processing incoming data streams on the CPU. According to Radix, RAIDIX ERA replaces hardware controllers and less efficient software RAID arrays.

Performance Optimization in Raidix ERA 2.0

On April 4, 2019, RAIDIX announced the release of the next release of the PO RAIDIX ERA for working with flash devices.

RAIDIX ERA 2.0 is an optimized version of software for creating fast and fault-tolerant RAID arrays on NVMe, SAS, and SATA devices.

Performance optimizations for various patterns are available in this release. The presented version of the software makes RAID "not lazy" and actively use the available computing resources not only at full, but also at partial load.

Compared to the previous release, RAIDIX ERA 2.0 has improved sequential write performance in small blocks. The updated sequence detector allows you to determine sequential or random recording with high accuracy and combine requests if necessary. As a result, the number of read-modify-write operations is reduced and the system speed is increased. And all this is at the high speeds inherent in NVMe drives.

RAIDIX ERA 2.0 allows you to increase performance also on low-flow patterns using the scheduling I/O parameter. This parameter is used for some types of load and allows you to send requests to those CPUs where they will be processed faster. For the main types of I/O loads, if possible, they are processed on the same CPUs that were received - this algorithm was implemented in RAIDIX ERA 1.0.

Tests have shown that the performance of RAIDIX ERA 2.0 on random write operations by the 4KiB block exceeds the performance of mdraid and Intel VROC by 120 times. Testing was performed using FIO 3.1 on the Western Digital Serv24 server platform with Ultrastar DC SN620 drives (3.2TB/1.2DWD).

Certification for Western Digital Ultrastar Serv24

On November 15, 2018, RAIDIX announced the certification of the RAIDIX ERA 1.0 system for the Western Digital Ultrastar Serv24 server platform. The symbiosis RAIDIX ERA and Ultrastar Serv24 will reveal the potential and speed of NVMe technologies, according to the company.

The Western Digital server platform is designed specifically for Software Defined Storage Intel Xeon both the 2 Platinum 8160 CPU and is equipped with 24 NVMe Ultrastar DC SN620 NVMe SSD 3,2TB drives. The total RAM volume was 256GB. The platform allows the installation of two additional network adapters.

Innovative technology will be required when implementing innovative projects that are based on IoT, VR, AI and when working with video in 8k and 16k resolution.

The bandwidth of RAIDIX ERA 1.0 was 21.5 GBps (read and write to RAID 6). Performance tests that were performed using the SNIA SSS PTSe v. 1.1 methodology showed the following random read results from 1 array:

RAID 6:

• Random Reads 4k — 5 600 000 IOPS
• Mixed RW 70/30 4k — 1 560 000 IOPS

RAID 5:

• Random Reads 4k — 5 600 000 IOPS
• Mixed RW 70/30 4k — 1 980 000 IOPS

We see that the emergence of a new interface creates new challenges for software developers for DSS, and the RAIDIX team is fully focused on promising NVMe and NVRAM technologies, "said Sergey Platonov, Deputy General Director of RAIDIX for Strategy.
