Up to 24 of these modules can be accommodated in a 2U controller housing. Each of these modules provides a capacity of 4.8 or 9.6 TB, up to a maximum of 19.2 TB (uncompressed). As a result, up to 384TB DRAID6 protected capacity is available in one 2U housing.

TOP 10 POST – 50,563 views on developerworks. Here’s another topic I often get asked about. Things used to be quite simple and I covered this for many years in my Configuring for Optimal Performance series of technical university presentations (also here on the blog – parts 1, 2, 3) – and the basics are still the same when configuring RAID arrays IBM Distributed RAID (DRAID) improves RAID performance and availability compared to Traditional RAID (TRAID). So why is this important? With today’s larger storage drives, minimizing rebuild time is critical, to avoid a double-drive failure and possible data loss. Finally, what about a DRAID6 array?

IBM Distributed RAID (DRAID) improves RAID performance and availability compared to Traditional RAID (TRAID). So why is this important? With today’s larger storage drives, minimizing rebuild time is critical, to avoid a double-drive failure and possible data loss.

As a result, the distributed configuration dramatically reduces rebuild times and decreases the exposure volumes have to the extra load of recovering redundancy. Using mismatched drives in RAIDZ2 or DRAID6 Hey guys, I'm new-ish to this arena of non-traditional RAID and trying to understand how capacities vary.

It is considered an enhancement to RAID level 5, but adds an additional parity block on each disk in the array. RAID 6 is also known as double DRAID6 seems like a good alternative to the traditional RAID10 even for critical workloads, if you are concerned about disk failures then configure it for two rebuild areas which allows you to loose two disks. If you are upgrading from a RAID10 spinning disk (15K) array to NVMe SSD array, strongly consider DRAID6 as an alternative. For compressed drives only DRAID5 and DRAID6 are supported.

When I introduced the updates in Spectrum Virtualize 8.3.1 I promised a dedicated post discussing the details around the new DRAID dynamic expansion feature. Before we dive in, there are some DRAID basic terms that you need to understand. Ibm iseries, AS400 and Ibm power systems including Power5, Power6 , Power7, Power8 servers, upgrades, parts DRAID6 seems like a good alternative to the traditional RAID10 even for critical workloads, if you are concerned about disk failures then configure it for two rebuild areas which allows you to loose two disks.

A timing window issue in the DRAID6 rebuild process can cause node warmstarts with the possibility of a loss of access (show details) Symptom: Loss of Access to Data:

Call NOW and speak to a Data Tech … DRAID6 seems like a good alternative to the traditional RAID10 even for critical workloads, if you are concerned about disk failures then configure it for two rebuild areas which allows you to loose two disks.

Supported RAID levels are RAID 0, RAID 1, RAID1E, RAID 10 … As others mentioned, first don't use RAID-5 with large hard drives (it's OK for up to 1TB SSDs and not much else). In my experience, rebuild time vary largely with storage solicitation. For idle systems, most of controllers will require 36 to 72 hours to rebuild arrays of 8 to 12 TB drives (depending upon your controller type and disk size).
