I've noticed there was no tutorial showing how to deploy Teams / Phone System from scratch so I've created one. A test environment can be easily created with an Office 365 trial and even phone numbers assigned to the system with a calling plan with no costs under the trial period. I...
I'm planning to refresh some servers I have at a datacentre and I'm planning to get everything on 10GB network. The idea is to use a couple of ZFS boxes replicating data to each other and between 4 to 6 hosts with VMware ESXi running the VMs over NFS on the ZFS boxes. My idea is to...
I think I'm going with Broadberry so far as I've spoke to them already and they seem to be okay.
Boston doesn't inspire much confidence with their crap website. Have you got any experience with either?
It seems SDS, NVMe and infiniband with RDMA are the best options
What do you guys think about these 2 articles?
NVMe Native vs NVMe Over Fabrics
iSCSI vs iSER vs SRP on Ethernet & InfiniBand
Not sure how accurate it is, but on paper sounds interesting
I had some large file transfer to do with severla million files, and ended up purchasing a software called syncback pro SyncBackPro backup software - the powerful solution
worth every penny, I use everywhere I need to transfer large volume of files, locally or over openvpn tunnels
Just an update on this topic as it had lots of input and ideas.
I'm running ZoL (ubuntu) on 2 boxes Dell R510 with a H200 flashed to IT mode, 12x 600GB 15K and 1TB Samsung 850 PRO for L2ARC and chinese intel X540-T1 for the 10gb network. So far working very well. I'm running about 10 RDS...
I got about 6 X540-T1 from ebay about 3 months ago, I didn;t know they were fake but considering I've paid about £100 each they must be. Anyway, they are working 24/7 on several servers for nearly 3-4 months now, no problems, but I'm now concerned about this knowing these cards are fairly...
AP lite doesn't use standard POE, you need an voltage converter to use on conventional POE switches. the AP PRO supports normal POE, I think is a bit odd from ubiquity, but everything else with the unifi APs is perfect
Very good article Patrick, very well written! Indeed, SATA seems to be on the way out.
So, is the only way to have RAID on a system with NVMe drives would be with SDS like vSAN, ZFS, EMC scaleIO?
I wonder if there will be any equivalent to a hardware RAID controller for PCI-E in the future.
by the way, I'm checking specs and endurance, the P3520 with 3 DWPD seems a very good candidate. the P3600 has also a 3 DWPD and costs nearly twice. I think the P3520 is a very good option for my workload.
I'm going to check Samsung prices now on the SATA models to compare and NVMe if they have...
I believe you have not see the latest models?
Prices here in the UK:
SATA S3520 1 DWPD 480GB £214 - 800GB £385 - 1.2TB £500 1.6TB £675
NVMe P3520 3 DWPD 450GB £253 1.2TB £530 2TB £850
Considering the performance difference, I think it is a no brainer to go for NVMe if we don't consider you...
What I like most about supermicro is that is the customisation, it feels like you are building your on PC, you know every single component, unlike Dell rebranding LSI controller with their firmware, and then always giving warning if a disk has no Dell firmware. I'm considering supermicro more...
