Good time of day wherever you may be, I'm looking to purchase 2(0r 3) new servers. The first would be to host my domains, and the second would be a cloud-accessible hybrid (SSD+HDD) or two separate smaller servers via nextcloud or similar programs. I'm not sure what the best equipment/brands and software would be for me, not sure if anyone has any insight they are willing to offer. Let me know if you have any questions! I've attached a few layout ideas I had below, any opinions are valid and appreciated. I'm a nube with the technical setup of all of this, my knowledge is in the physical hardware. Thanks! Edit: Forgot to give numbers, Looking to have a small cache of SSD Storage for active projects(Partition 1:1-3TB Active), and then a larger Archival HDD portion(Partition 2:10-20TB Active). I'll only be populating a few drive sleds initially and expanding with time to fill. Not sure if i can combine both servers and both host and control the SAN racks in one chassis? Any thoughts on this idea? Thanks!

Hello again. Bunch of random posts going on here from yours truly, but that cannot be helped. I have a chassis for an EMC VNX 5100. Very old, but I have access and want to use it for storage. However, I have had some issues with connecting to the box itself. The box itself is on the network at its default address (192.168.1.1), however, it refuses to connect. After doing a port scan I found out that EVERY SINGLE PORT is closed. I have no idea why, but it is. The only other way to connect to it is through a proprietary serial connector (image attached) by setting it up with a Dial-up connection on Windows 7. The only problem is this cable doesn't work. Dell forums don't seem to be much help, and I can't find any helpful documentation on this. Any ideas/advice? Also I have not been able to find where to get this specific connection, as it appears to be proprietary.

This is a project I've been meaning to get off the ground for quite some time. Given my work schedule I only predict I'll be able to work on it and post updates once a week so to all who chose to follow along I ask for your patience. For those clicking because they're not familiar with the SAN & iPXE terminologies: This is a special network project I've been planning and have had in the works for a number of months. Finally I have everything I need to get it started and I figured some of you might like to follow along. I plan to write a full tutorial based on what ends up working here if you'd like to try building something like this yourself. The focus of this build log is to setup a small series of servers so that they all boot off of a network resource. The reasons for doing this are: Ease of Repairability Reduce Downtime Ease of Scalability Overall it's very cool to me and I want to play with it. :3 The build log is going to consist of four main stages: Preparing the network hardware (assembling, configuring, firmware updates) Setting up our hypervisor server (installing NICs, configuring IP's, preparing Virtual Machines) Configuring the hosting servers (iSCSI & DHCP servers) Setting up the client servers (establishing iSCSI connections, installing OS's from scratch) In the end these client servers will act as nodes and with this network additional nodes will be added in the future. For the time being this is the network hardware we'll be working with: 2x PCIe-10G-SFP+ made by TG-NET based on the BCM57810S controller. These will be installed in the hypervisor server and will be in charge of hosting the virtual disks our nodes will boot from. 3x 10Gbe SFP+ Mellanox ConnectX-2 MNPA19-XTR network cards These 10 Gigabit NIC's are very old but very cool for networking aficionados, did I mention they're cheap? 14x FiberStore 10G SFP+ 850nm 300m transceivers. These are cheap SFP+ modules that convert the electrical signals that the NIC puts out and converts them to laser light signals that we can hook-up our fiber patch cables to. 7x OFNR LC/UPC-LC/UPC 50/125 OM4 Multimode Fiber-optic patch cables These are a inexpensive glass/ceramic composite fiber optic patch cables. They're easy to get and are good for short runs. I've only tested them for 10Gig up to 50ft but I'm sure you can use them for longer runs. Tonight is just an introduction. I will try to get something started tomorrow. I'm excited to get this underway and to try and overcome the hurdles I'll inevitably have to cross.

So I have always wanted a ZFS HA SAN for the house, and a project at work introduced me to OSNexus QuantaStor, as well as their amazing CEO/CTO Steven Umbehocker who ended up handling my sales call during December a year or so ago while his sales staff was I guess doing holiday stuff. After talking with him about my personal setup he informed me that they have a free/community edition of their full-featured product, this includes HA, FC, scale up and out, and you can get up for 4 licenses to play with it kinda however you want. It is a bit of a learning curve coming from TrueNAS for the past 10+ years but overall, I am very happy with it. The community edition only supports 40T of raw storage under a single license, but for home use, that’s probably more than I am going to use for how I have things setup. Anyway tl;dr, here is a look at my new ZFS HA SAN. I am using a SuperMicro SBB 2028R-DE2CR24L. It is a dual node server where both nodes have access to all 24 SAS bays up front and even has room for SAS expansion out of the back. I have replaces the 10G NICs that came with it with 25G Broadcom P225P. I am using 6 Samsung PM1643 3.84T SAS SSDs for the pool. I have a RAM upgrade on the way to take this from 64G per node to 256G per node and for now, the dual E5-2650 v3’s are enough for the load that I am pushing. I am running the QuantaStor Technology Preview version of the software so I can use ZSTD compression and be on a rather new build of OpenZFS as well as it being an easy upgrade path from QuantaStor 5 to QuantaStor 6 when it comes out. random IO. ~4,195.51MB/s read and ~3,713.16MB/s write

This is going to be a bit of a long question mixed in with a story so sorry in advance. So, many months ago I ordered a second hand SAN (Similar to a NAS) from Ebay (Dell Equallogic ps4000XV) which works great and 9 second hand WD RE 2TB hard drives which are unsupported but at the time appeared to be fine. The only thing that I didn't understand was that the drives were reporting to be running at 5400 RPM instead of 7200RPM which was strange as the drives should be 7200RPM however, I didn't think twice as all drives were the same and because they are technically unsupported Now this setup worked fine in an ISCSI setup for ages until 2 of the drives failed. Now, I don't run it all the time and I was expecting the drives to last longer but I thought maybe I just had 2 bad drives and I ordered 2 more identical drives but this time I ordered them new on Ebuyer and installed them and since I was running a raid 6 no data was lost and the SAN rebuilt everything fine. This happened a fair few months after the original drives and maybe 2 months ago. Anyway, I have just looked at the disk interface and I have noticed that the 2 new disks I ordered report an RPM of 7200RPM which is the correct speed for my drives but the others still report 5400. Anyway back to my question, I was wondering if you people thought theses original disks I ordered from Ebay are fake/dodgy or not, noting else about them appears wrong or fake and its only really the speed which is making me question the authenticity of the drives? The model numbers of the drives in question are WDC WD2003FYPS-27W9B0 or WDC WD2003FYPS-27Y9B0

Hey All, I have the option to get a NetApp DS4243 with 24 450GB Drives for fairly cheap and I wanted to use it as a homelab SAN as well as a backup box. For a controller I read that you can get a NetApp X2065A 4Port HBA for a JBOD passthrough to the server. Im wanting to double check that Im in the right here. Edit: The OS I'd use for the server would be something like Windows Server 2016. I'm also wanting maybe an HBA that has Raid enabled on it for something like a raid 6. However Im thinking thats really expensive.

I have an unRAID setup but have been experiencing some problems lately with either hardware or software, it has started to get a bit frustrating. I want to setup just a file server and offload the hard work to a dedicated workhorse server. Curious if anyone has experience on building SAN or where one could go for a good place to start?

Hey guys, doing some upgrades to my home lab setup and need some advice. I don't have a lot of experience with SANs, so I want to make sure I'm doing this right. I'm using this lab for my various Cisco and other studies. Here is my setup: Bunch of Cisco IOS devices 3x Cisco UCS C250M2s, 2 with 196gb RAM and 1TB storage via 8 10k 2.5 SAS drives, 1 with 384gb RAM and 1TB storage via 10k 2.5 SAS drives (all 3 running RAID 0, yeah yeah I know bad) 1x Xeon E3-1226 with 16gb RAM and 3x 4TB WD drives running in RAID5 (currently my Plex/storage server) So here is what I'm thinking, I'm basically maxing out my storage across my lab servers (UCS boxes) and I want to get a SAN to ease the storage burden here. But I'm also running a lot of VMs across these platforms so I want to make sure I'm not going to hurt the current performance. I'm thinking something like this: http://www.natex.us/24bay-FreeNAS-p/24tbfreenas.htm Will do the trick, with 24 1TB drives in a RAID for some redundancy. Maybe throw in a 1TB SSD for a cache if that will increase performance. And 10Gb fiber channel cards with a 10Gb switch. Do you guys think this would perform OK with 100+ VMs? They aren't necessarily intense applications running, and the performance is fine on the servers now. I just want to make sure I don't negatively impact performance by introducing a fiber channel link to pull the data I guess. I have very very little knowledge about this stuff. The other issue I see with this build from Natex is 3 RAID cards, not being a RAID guru but I assume there is a way to bring those together into a single array? If anyone has suggestions it would be much appreciated. Thanks - Dom

Hello, I need to replace a few failed hard drives in a SAN I run at home. I am currently running 9 WD RE 2TB drives in a RAID 6 but 2 have failed. The drives I ordered were second hand however I want to replace them with new when they fail as these drives are proving to be very unreliable. The only issue is that i'm not sure if I should just replace with the same RE drives but new drives or if I should use WD gold drives. Both drives have very good and very similar specs and I know WD RE drives were intended for RAID configs but the gold drives just seem slightly newer and maybe better in the long run? https://www.wdc.com/content/dam/wdc/website/downloadable_assets/eng/spec_data_sheet/2879-800074.pdf https://www.wdc.com/content/dam/wdc/website/downloadable_assets/eng/spec_data_sheet/2879-800066.pdf I am hoping someone has experience with these 2 drives or if someone knows of any real differences? If helps, I am running the drives in a Dell Equallogic PS4000XV SAN

Hi Guys, Need a bit of help I have been tasked with looking for the correct PCI cards that will work with the below SAN and also what cables i need: San: MSA 2052 iscsi 10GB Need the Card for a ML350 Gen 10 to connect to the 10gb iscsi I have spent hours looking for the relevant card and cable I need to connect this san to 1 server for a client. I know that I some people will say I shouldn't be touching what I don't understand but this is for a client and this is how you learn ;D any help would be a massive help as I need to have somewhat of a proposal ready tomorrow for them. Thanks in advanced David

I have brought a hp P4300 G2 server and am looking into operating systems and file systems to run on it? -
We will be moving to 4K video soon and I am trying to get my infrastructure in place before that happens. I would like to get a 16 bay 160TB or 192TB Rack Mount style NAS. I would also need a decent MAM software and Archival system. We have 4 and soon to be 5 Edit station that will be editing with several streams of 4K video, some multi-cam (4 camera angles) and some not so much. So I need something that is fast and can handle multiple streams of 4K simultaneously with little or no latency. Currently we are on Macs editing on FCPX but we are considering switching to PC and Black Magic Design DaVinci Resolve 16 as soon as it gets out of beta. Not sure if any of that makes any difference. I am working on getting the 10GbE cabling and switch now. What is a good NAS to look into for my needs? Would a SAN Be better and Faster or is NAS the way to go for shared media storage? Thanks for your help!

Hi, i'm looking at a replacement SAN for our esxi hosts, we have about 20 vm's running between 2 hosts, currently using a 4Gb link direct to the SAN, however.. our SAN is due to be replaced and repurposed and i'm looking at upgrading to 10Gb Ethernet direct to the hosts with at least 36TB of Storage with possibility to expand if needed. i've had some quotes back for just over 10k in GBP, and would like to see if i can do better, i'm not mega familiar with what sans are out there and which ones to avoid, so i'm really looking for recommendations, it must have ideally quad 10gb ethernet, at least 2U, but can be larger if needed doesn't matter. reliable and robust for 24/7 running, obviously the configuration of the actual array will be decided one we know storage capacity and amount of drives. this is for a educational environment not for myself, so it MUST be reliable. Cheers guys !

Hello All So I am based in the UK which limits what I can buy and where from. My 10 year old Synology NAS has just failed. - All good things come to an end. So as I have the HDD, and I have a very new and high powered Dell server. I was wondering what you guys would advise for a replacement. I was looking to buy a MD3000 to connect to the server, but have then read you cant just dump any SATA HDD in them as the unit will only work with Dell branded disks. So kinda pointless for me. Based on that I am wondering what I can get that would be good price which is ready made either branded from another company, etc where I can connect this to the Dell Server via a external SAS connector, where I can present the disk to the server and away I go. Something like the NetApp - but while these are OK price in the UK the cable needed to connect a NetApp disk shelf to a server are stupid money. (just for the cable) so this kinda rules this option out for now. It maybe I end up getting another Synology box but before I do I wanted to see what else I can get for my money thats say ex enterprise kit. I have a full rack at home so space isnt an issue. Thank you for reading and I look forward to the comments.

So I acquired a server and am in the process of upgrading some of the hardware for my needs. At first I was going to split the storage in half having a SSD and a HDD datastore. The HDD datastore would consist of 5x 4TB or more drives. This would strictly be for Plex Media server. However I was then going to have a SSD datastore containing 16x 480GB drives. The realization of how much it would cost finally hit me, 16x Intel SSD's would be around $1800. So I got to thinking about it and even with 10Gb networking is a SSD storage array even worth it??? The SSD storage would be used for programs such as games and other applications that are otherwise meant to be run on a local computer.

So I'm in the process of building a new server and would like to have a SSD storage array. My question is would it be worth getting a used server SSD like the Intel S3500 480GB or would it be better to just get a consumer grade brand new SSD for around the same cost?? Thanks!

So I have been tasked with something that is a bit large for me. I am used to handling some fairly big projects on my own, and normally I will handle this sort of project from the ground up. All the research, implementation, etc. But this one has brought some interesting challenges and some very time intensive research. And a friend thought I should bring it here, and honestly, I thought it would be indeed interesting to see what sort of recommendations I get from this online community. I have been tasked by my job to look into what it will take to start providing an online cloud-style storage service for public use. This means a system that can handle storage of files for a client. Most likely backup files and things of that nature, mostly cold~warm storage stuff. Since this will be a startup, costs is a high priority item, but the main priorities are as follows Reliability Performance Capacity in that order. Now I have come up with something that might be a viable solution and will post it upon request, but as I am looking for recommendations. I don't want to taint the recommendations by posting what I am looking at already. And I don't intend this to become a massive argument for why I should or shouldn't implement my current plan. Instead, I would like others to offer up solutions that they might recommend, and maybe some pros and cons I will be looking into all of them and comparing to see what will best fit all of our requirements. Mainly what I am looking for is some sort of SDS (Software Defined Storage) solution. I am not too interested in looking into proprietary hardware storage solutions like Dell EqualLogic, as the cost can get very expensive very quickly. But still, I will hear out any argument if you want to state your point of what you believe will work and why, regardless if its hardware based or not. Ideally, this system will be used for storage of backups and things of this nature. I don't intend people to use this as some sort of pool for their data-intensive software such as a SQL database, although flexibility is always nice. I am primarily interested in block and/or file style of storage My main focus is Throughput and reliability. IOPS is not at the bottom of this focus list, but it's not the highest priority. I expect customers to store data for the long haul, and most likely large single files. I am thinking something like 3x replication on this system to ensure maximum reliability. I don't expect anyone to hold my hand through any of this, as I will gladly put in the legwork to figure out how a particular solution ticks. But I have hit a point where I have my mind set on a certain system. And I have a sneaking suspicion that I haven't explored as deep as I can, and there may be a contender I have missed. But ultimately I am tasked to take this venture and see how it can be done, what are start-up costs etc. Eventually, if this plays through, in time it will scale into a full-fledged data center. Like I said, I can post what I am looking into currently upon request, otherwise, I am curious to see where your minds wander to.

Hello everyone, I have a Cisco MDS 9124 multi-layer fabric switch that I am trying to configure. However, in order to do so without knowing much about configuring through the command line I need to find Cisco Device Manager. In order to view it on Cisco's website I need to have an open account with them. I am just a student who received the SAN equipment and switch from my school, and do not have an account. If anyone could give me some suggestions it would be greatly appreciated!

Hi Guys, I'm hoping what I'm wanting to achieve is possible. I have TWO options i'm willing to accept. 1)I'm looking to have a motherboard that supports TWO RAID array's running with TWO m.2 ports, which i'd like to raid 1 (for redundancy), and then id like to have another raid array via SATA to 4 1tb SSD's on raid 10. I can take care of CPU, GPU, and ram easily, its the storage part I'm worried about. Most motherboards that offer m.2 say that if you use the m.2 port, it 'uses' the SATA ports 0_1 and 1_1 (or some variation). Id NEED those sata ports, so I'm looking for a motherboard that'll achieve this. 2)I'm a sysadmin, and my current job is recycling a server (out of warranty) as well as two SAN's. Id like to use this as some sort of 'hot' data and 'cold' data storage. I'm hoping there is some sort of product or software that can prioritize what data I use the most on my PC, and put the data that ISN'T used very much on the san(standard HDD's) where as it can see I use ____ data more often, and keeps that on the raid 10 array of SSD's. I'm open to ANY help the community can offer!

We're looking at building and 80-100TB StorageVault that we can back up to with Veeam. We've bounced back and forth between Raid6 with 24-4TB drives and have 2 hot spares or a Raid10 setup with 40-4TB drives. The Raid 6 setup would have insane rebuild times but the Raid10 is a ton of drives and not sure how well a storage array that big would be used/recognized. What would you guys do? Any other options we may be missing?

Currently, I've done it with Fedora 26 and 27. I am using 4Gb FC HBAs, qla2462 model. Got them for real cheap from 3rd party seller. Basically you put the card in target mode and using targetd you can share luns/disks/etc over fibre channel. Using multi-path software you can easily increase your throughput. I have not bought a san switch and I dont need one, just going point to point. I have been playing around with zfs on linux and creating zvols for export to my promox server. some random screenshots while I was doing initial setup: You can see the I/O spread over both links... cannot add the rest of the HBAs I got until I have more PCIe slots.... Created a VM on my promox and passed the lun directly to the VM for some testing.

Hello guys, So I got my hands on this "beautiful" device - SGI Infinite Storage 200. However, I've got a problem setting it up. SHORT VERSION - I AM LOOKING FOR A WAY TO SET THIS THING UP WITHOUT SERIAL PORT, OR ETHERNET USE. I AM ALSO LOOKING FOR A PROGRAM CALLED "SGI INFINITE STORAGE SYSTEM MANAGER" The whole story: I do have plenty of hardware and network experience (in fact, I'm admin of my own server-operation, with over 100 linux-based servers running currently online, all done, setup and managed by myself.) However, I'm more into the computational stuff and not really into storage. The need came and I got my hands on this 10 years old hardware, basically for free. As long as it is only for my personal, long-term backup storage, I do feel comfortable using it, even given its age. So, to my problem > My current setup looks like this > SGI IS 200 - connected via 4gbps fibre directly to my storage-host DL360 G7 (Dual X5660 + 64GB RAM) via a QLE2560 QLogic fibre card. If I enter the cards management utility during the bootup, I see the SGI IS 200 connected, I can access it, however I can not see any individual discs or any raid setup, whatsoever. After I boot vmware, I can see 2 SGI fibre drives however, they are 20/10MB big and I can not delete them, nor repartition them. My guess - The SGI IS 200 has integrated raid controller, and shares only the whole raids through the fibre connection. The two disks I see are remainings of old raids, that were present on the server before it was given to me, however due to the missing drives, they only show up as "really small units". And now FINALLY MY QUESTION: HOW TO CONFIGURE THE RAID WITH NEW DRIVES??? Because no matter how many drives I stick in, I can always see only the 2 drives (20 and 10MB big in size), and I've tried so hard, but had no luck setting the SAN up myself. The SGI IS 200 has integrated ethernet jack, however it does not seem to work right. It does not retrieve IP from my DHCP server, inspite of the port being "active - status leds blinking" - my guess is that it is configured for a static IP, which I have no way of finding out. I've read through all manuals available, however I came to only 3 conclusions: 1. I can not set it up through online interface, because the port is configured incompatibly with my network. 2. I could reconfigure it using serial port, which I have no way to connecting to. 3. The unit is able to be configured through fibre, using program called "sgi infinite storage system manager" however, I had no luck finding it online. So, am I stuck with a brick and should just find something else, or is there any way, you can help me solve this problem? :) I think that the best way would be to get the software, or to find some way to reset the controller board to retrieve IP from my DHCP and let me configure it via network interface. Thank you very very much, Every advice appreciated :)
