RAID controllers for System x and iDataPlex servers supported with hybrid HDDs (Part 2) Part NAND memory is divided into two parts: eMLC flash memory is used as a read cache for frequently used data and SLC flash memory is used as a non-volatile storage for write cache in DRAM in case of a power failure. DRAM memory is used for buffering all reads and caching all writes. HDD memory is used as a primary data storage for all data. Hybrid HDDs integrate three media types: HDD, DRAM, and NAND. ![]() (self-monitoring, analysis, and reporting technology) support ECC maximum burst correction length of 530 bits.Support up to 6 Gbps SAS interface speeds.Improve performance of server internal storage in lower cost configurations, without a need to utilize SSDs and storage tiering.Transparently cache data at I/O block level.Bring transparent enhanced performance to data with high locality ( hot data).Enable higher IO performance while leverage the capacity and cost of spinning media for primary storage.Combine a cache of NAND flash and conventional media to accelerate hard disk drive performance.Industry standard 2.5-inch form factor supports 2.5-inch drive bays on selected System x, IBM iDataPlex®, BladeCenter® and IBM Flex System™ servers.Jails: running 1 iocage jail (Plex) using danb35's script:Īdditional NIC: MELLANOX 10GB CONNECTX2 - MNPA19-XTR Take a look here: A post with Links to useful threadsThe IBM SAS 2.5-inch Hybrid HDDs have the following features: Vdev-1 = 4 x 6 TB drives in RAID-z1 (4 WD Gold drives - WD6002FRYZ)īoot pool: 1 vdev with 2 x 40 GB notebook drives in mirror (2 drives total - FUJITSU MHW2040BS) Vdev-0 = 4 x 6 TB drives in RAID-z1 (4 WD Gold drives - WD6002FRYZ) Vdev-1 = 6 x 4 TB drives in RAID-z2 (6 Seagate Exos drives - ST4000NM0115) Vdev-0 = 6 x 4 TB drives in RAID-z2 (6 Seagate Exos drives - ST4000NM0115) Vdev-1 = 6 x 4 TB drives in RAID-z2 (6 Seagate Desktop drives - ST4000DM000-1F2168) Vdev-0 = 6 x 4 TB drives in RAID-z2 (6 Seagate Desktop drives - ST4000DM000-1F2168) HBA: LSI/Broadcom SAS9207-8i, 6Gbps SAS PCI-E 3.0 HBA - flashed to IT Firmware: 20.00.07.00Ĭonnected to: two 6Gb/s 24-port 3.5" mini-SAS expander backplanes (80H10024001A0) 128 GB of 16GB sticks Samsung brand PC3-12800R, DDR3 Registered ECC Processor: Intel Xeon E5-2650 V2, 2.6GHz 8 Core (16 thread) System board: SuperMicro Motherboard X9SRL-F, LGA 2011/Socket R, IPMI For a home NAS, this chassis is huge, able to hold 48 data drives and two boot drives with a couple spaces internally for non-hot-swap drives. The three pools in this one system represent the three NAS systems I had before the consolidation. I have even put together some hardware just to test things out a time or two.įor a while I had three systems, all at once, at home but I am making some hardware changes right now and only one NAS is online. I made some mistakes along the way, learned some and I try to share some of those lessons learned experiences here in the forum. This is the 8th FreeNAS unit I have built for home. This one was built in 2018, but I reused the name from a previous build. ![]()
