...the load created by raid resync so we are considering to skip raid alltogether and rely on gluster replication instead. (by compensating with three replicas per brick instead of two) our options are: 6 of these: AMD Ryzen 5 Pro 3600 - 6c/12t - 3.6GHz/4.2GHz 32GB - 128GB RAM 4 or 6 ? 6TB HDD SATA 6Gbit/s or three of these: AMD Ryzen 7 Pro 3700 - 8c/16t - 3.6GHz/4.4GHz 32GB - 128GB RAM 6? 14TB HDD SAS 6Gbit/s i would configure 5 bricks on each server (leaving one disk as a hot spare) the engineers prefer the second option due to the architecture and SAS disks. it is also cheaper. i am concerne...

Hi, my oi151 based home NAS is approaching a frightening "drive space" level. Right now the data volume is a 4*1TB Raid-Z1, 3 1/2" local disks individually connected to an 8 port LSI 6Gbit controller. So I can either exchange the disks one by one with autoexpand, use 2-4 TB disks and be happy. This was my original approach. However I am totally unclear about the 512b vs 4Kb issue. What sata disk could I use that is big enough and still uses 512b? I know about the discussion about th...

...ater with 10Gbit interfaces. We are seeing 100-150MBytes/sec read or write performance between the Mac and the FC13 system over 10Gbit interface but it should be capable of 400-500MBytes/sec. We have a local raid on the FC13 system that runs 1GByte/sec locally using an Areca 1880-ix-16 raid card (6Gbit version). It has 16 fast Hitachi disks in a Raid5 format using xfs filesystem. The problem here is that samba is poking the Areca at 128KByte I/O's on preads and writes, i.e. shown to us using strace on the smbd daemons that are running. Using vmstat/iostat/sar utilities, we see 100% utilizat...

I have three zpools on a server and want to add a mirrored pair of ssd''s for the ZIL. Can the same pair of SSDs be used for the ZIL of all three zpools or is it one ZIL SLOG device per zpool? -- This message posted from opensolaris.org

...tially lane sharing. A SAS expander in many ways is like an ethernet switch. You have 8 lanes coming off your SAS3008, 4 each in the SFF8087 connector or 8 individual SATA like sockets on the motherboard. You can plug any number of these into a host port on a SAS expander and you then have n*6Gbit of bandwidth to the expander from the host. Then you plug targets and/or additional expanders into the downstream ports. Everything on the downstream ports has to share the bandwidth so you can run into a wall if you try to push to much bandwidth to to many devices at once. In practice thoug...

Are any of you using the Intel 320 as ZIL? It''s MLC based, but I understand its wear and performance characteristics can be bumped up significantly by increasing the overprovisioning to 20% (dropping usable capacity to 80%). Anyone have experience with this? Ray

The default blocksize is 128K. If you are using mirrors, then each block on disk will be 128K whenever possible. But if you''re using raidzN with a capacity of M disks (M disks useful capacity + N disks redundancy) then the block size on each individual disk will be 128K / M. Right? This is one of the reasons the raidzN resilver code is inefficient. Since you end up waiting for the

A customer is looking to replace or augment their Sun Thumper with a ZFS appliance like 7320. However, the Thumper was used not only as a protocol storage server (home dirs, files, backups over NFS/CIFS/Rsync), but also as a general-purpose server with unpredictably-big-data programs running directly on it (such as corporate databases, Alfresco for intellectual document storage, etc.) in order to

While I understand everything at Oracle is "top secret" these days. Does anyone have any insight into a next-gen X4500 / X4540? Does some other Oracle / Sun partner make a comparable system that is fully supported by Oracle / Sun? http://www.oracle.com/us/products/servers-storage/servers/previous-products/index.html What do X4500 / X4540 owners use if they''d like more

My google-fu is coming up short on this one... I didn''t see that it had been discussed in a while ... What is the status of ZFS support for TRIM? For the pool in general... and...

Morning all... I have a Dedicated server in a data center in Germany, and it has 2 3TB drives, but only software RAID. I have got them to install VMWare ESXi and so far everything is going ok... I have the 2 drives as standard data stores... But i am paranoid... So, i installed Nexenta as a VM, gave it a small disk to boot off and 2 1Tb disks on separate physical drives... I have created a
