I’ve played with many storage technologies at home, ZFS being one of my favs when it comes to performance. But i’ve been looking for something that suits a typical home environment where power usage and capacity is usually more important than performance. Thats where UNRAID has come in…
UNRAID give me these advantages;
- Different sized disks in a single pool (only requires largest disk as parity)
- Files are distributed over all the disks – so even if you lost more than a single drive you still still have some of your data. Note : with parity drive you can handle a single drive failing without loosing anything, sorta like RAID4 – non distributed parity.
- Power usage, since the files are stored on specific disks not all the disks need to power on to give you your file.
- Runs on a USB stick – no large operating system required.
- Crashplan module can be installed to provide backup options.
I’ve run through this exercise again – my old findings here
4 x 500 WD Black drives — in one big RAID 0 (128K blocks)
and again only using 500GB of capacity (roughly 1/4 of each of the drives)
The 9.5 release is a comprehensive release that includes enhancements in the following areas:
- Application managed snapshots for VMware ESX Server and Microsoft Hyper-V Server
- SAN Status Home Page — the SAN Status home page is the new home page for the CMC and presents key information for all management groups in the storage environment in a single view.
- Zero to VSA automated installation and deployment — Single installer can install VSA, FOM and CMC. Go from “zero” to a fully functional virtual SAN in just a few easy steps. Scriptable install tool allows ROBO customers to script install once and deploy VSA quickly at multiple remote locations.
- Peer Motion data mobility with cluster swap — Cluster swap allows users to replace or upgrade P4000 clusters. Edit cluster menu guides decisions about adding, removing, or exchanging storage systems. Easily migrate data online between tiers.
- Remote Copy performance improvements — Improvements to remote copy times, the time required to scan volumes, ability to support more frequent snapshots, reduction of RPOs for DR solutions.
- Storage Replication Adapter for Vsphere Site Recovery Manager 5.x — Supports automated failback and is included on the HP P4000 Application Integration Solution Pack
- Best Practice configuration wizards — Configuration wizards guide towards highest availability configurations: add Failover Manager for 2–node configuration, configure disk RAID 6 for single-node configurations, recommends volume replication when expanding clusters to more than one storage system
Change SSHD to allow root login;
PermitRootLogin = yes
Allow remote logon for root user, comment out the following line;
rolemod -K type=normal root
Setup iSCSI target using comstar –
pkg install -v storage-server
pkg install pkg:/SUNWiscsit
svcadm enable stmf
svcadm enable svc:/network/iscsi/target:default
reboot — -r
Create the iSCSI store —
zfs create -V 100G DataPool/TestDatastore1
sbdadm create-lu /dev/zvol/rdsk/DataPool/TestDatastore1
stmfadm create-hg ESX4-group
stmfadm add-hg-member -g ESX4-group wwn.2100001b329711bd wwn.2101001b32b711bd
stmfadm add-view -h ESX4-group -n 0 600144F03EBEC50000004BA86E460001
stmfadm list-lu -v
