  1. UGH, I wish I knew this before of this option. As always, thanks a lot for your guys' help.
  2. Hi, we have a Dell 730xd that we bought 6 months ago and we just bought some Samsung NVMe 1725 2.5" 1.6TB drives through dell to put into the server but are running into some issues....the disk was already in a 2.5" cage so it inserted right into the front of the server, but.... 1) Not seeing the drive in H730 mini PERC or in iDRAC (dell support tells me that it passes through directly to the OS so I won't see the drive in perc or idrac?) Is that accurate? If so, how would I raid then? 2) I dont see it in vmware either.... We are on VMWare version 5.5, and the latest DRAC and BIOS versions for the Dell (but didnt upgrade the raid controller yet) Any ideas?
  3. Thanks guys, is there a concern then witht he 2.5" or even the add-in PCIe card if I can't raid them for production data? KEvin, so you're saying chances are the server I got 24 drive bays that are SATA/SSD but no NVMe...
  4. Thanks Kevin....but I looked at the instructions for the SM1715 (which I think uses the same connectors) and it says I should just be able to plug it into the front? They even happen to show a Dell server in the image... http://www.samsung.com/semiconductor/global/file/insight/2015/08/NVMeSSD_User_Installation_Guide_whitepaper-0.pdf If this isn't the case do I need some sort of additional part? Even if I do, only VMWare can see it right and not the PERC? How can I RAID them then?
  5. Hey all, we currently use the Samsung Pro 850 SSD drives in our Dell desktops today but want something a bit faster and am looking into the Intel 750....but as far as I can tell the Intel 750 (2.5" or the PCIe) won't fit into the desktop motherboards (different connectors or whatever among other things)......any ideas on how to get around this? Is there another SSD that I should look at that is comparable/faster than the 750s? Thanks.
  6. Hi, I wanted to upgrade some of our disks (local disks that are Toshiba SSDs) in our Dell VMWare host to something considerably faster and looked into the Intel 750s but realized they are more for consumers due to low writes/day and durability...which sucks because the pricepoint is great for its performance! Are there equivalent, similar pricepoint, same performance SSDs (2.5" or PCIe) enterprise or semi-enterprise grade SSDs that could work? Thanks.
  7. Thnks, but just so to be clear..there is no 1.2TB SSD option with the same performance as Intel 750 for the same or a little more price, SATA/SAS or PCIEx3?
  8. So.....I guess there is nothing then

    Fast desktop SSDs?

    How much more performance would the Raid0 give me? How about Raid1? CPU is a core i7 with 8GB ram....and both of those on task manager seem fine
  10. Hi, it is an option if there are larger drives, preferably 1.6TB or above but I guess 1.2TB would be ok too. FYI, I have a similar topic for desktops open as well if you have any suggestions.

    Fast desktop SSDs?

    Very heavy excel workbooks and proprietary applications....trying to keep the cost around the same as the Intel 750 400GB model but could go a bit higher as long as performance is comparable or better Thanks.
  12. Hi, sorry for the late reply, trying to keep budget around the same cost as the Intel 750 800GB but that seems unfeasible... For my ESX Dell 730xd server trying to get to ~3TB in Raid 5 or 10....or if a PCIe not sure how Raid works with it or if I even need it Currently we have Toshiba PX02SMF080, 8 of them in Raid 10 (again, local storage, no SAN) Below are the ports available in the server Drive Bays Internal hard drive bay and hot-plug backplane: Up to 18 x 1.8” SSD: SATA Up to 24 x 2.5” + 2 x 2.5” HDD: SAS, SATA, Near-line SAS SSD: SAS, SATA, Up to 4 NVMe Express Flash PCIe Up to 16 x 3.5” + 2 x 2.5” HDD: SAS, SATA, Near-line SAS SSD: SAS, SATA

    Specs of a Dell SSD?!

    They say its either one of the below Seagate 1200 drives...but don't know which one for sure, really hoping its the 43 one as it seems faster! ST800FM0043 ST800FM0013 Thanks
  14. Hey all, as we all know Cisco, Dell, HP make it quite difficult to find out the exact specs on the SSDs that they use as they mark up the price 3-6x easily as they are usually rebranded drives. We are considering going SuperMicro because of this reason so that I know exactly how many IOPS/Read/Write/DWPD/etc. I am getting. On my Dell quote it says " 800GB Solid State Drive SAS Mix Use MLC 12Gbps 2.5in Hot-plug Drive,13G" , but I am having trouble finding out any details about it and Dell is unsure themselves. I think it might be a Seagate or HGST but the Dell guy doesn't think so, so I am not sure. Anyone here what the specs are? Thanks in advance.

    Dell just told me it is the Seagate - ST800FM0013. SSD Review seems to think it is a Toshiba
  16. Hey guys, read the review on the VRTX (http://www.storagereview.com/dell_poweredge_vrtx_refresh_13g).....and had a few follow up questions. First, a quick background... We have 3 old ESX hosts attached to a Dell Equalogic SAN and we need to upgrade the environment. First we consider getting a new SAN and then decided against it Second, we considered vSAN but decided it was too new and extra cost of licensing wasn't worth it Third, we consider three new ESX hosts with local SSD disks (no SAN, each server has its own local disks), and then use replication software for data protection / high availability We are now considering a Dell VRTX, does anyone have experience with this? As mentioned in the review....it is a 4 blade (or node depending on terminology) solution that uses all the drives as a single data pool for all the nodes, so I would install the ESXi on the 4 nodes and all of them would see the same data pool (is this accurate?). So I was thinking of using 12 of the bays in Raid 6 SSD drives for high-need VMs and the other 12 drives in Raid 10 1.2TB 1k RPM drives for the other VMs. I guess I would also need another external maybe 1-2U servers to replicate to for protection/HA? It seems to be a direct attached storage solution so my first question is obviously about the VRTX in general, second question is is direct attached storage different than a SAN? or a vSAN? or is it still local storage? Would there be performance issues with this? As in 4 nodes (and all the VMs on it) sharing the same data pool? Does the VRTX also mean single point of failure? Thanks

    Dell VRTX - is it right for us?

    Not cost as much....I just HATE that it somewhat serves as a single point of failure for ALL your hosts, and you need so much more overhead in terms of management with it; additional switches, additional vLANs, additional QOS, additional cabling to manage, additional consoles, additional DR (SRM + SAN to SAN), additional troubleshooting, performance problems, etc etc etc. With 2-3 new hosts I simply keep everything on the same network and subnet and have everything going into the same switches, configure replication software, and boom, done. At least that's how easy it is playing out in my head Thoughts?

    Dell VRTX - is it right for us?

    Each host has 2x Xeon X5550 CPUs (total 8 cores per server)....and CPU usage is about 7-10kMhz (40-60%). In option#3 in my original post I mentioned simply just getting 2-3 new servers with local storage and 2x 2697v3 CPUs per server and that being enough to handle any growth as well REALLY trying to stay away from a SAN, we have 5 year old Equalogic 6000 now and I hate it (26 x 600GB 7200k RPM drives in Raid6)

    Dell VRTX - is it right for us?

    Thanks Brian....first of all we simply need to upgrade our hardware due to it becoming end of life. Secondly, we need more SPEED (due to proprietary application), hence SSDs (likely Samsung Pro 845DC Pro) and high availability (RTO and RPO of under 10 minutes).
  20. Hi, read your articles on the Micron M600 and Samsung Pro 850s....great work! As useful as the information was I am a bit more confused about which drives to get for our servers (looking at getting 2 SuperMicro's STX-NL with the LSI MegaRAID 12Gb/s controller with 1 gb cache). They will be VMWare ESXi servers. We are considering the M600 1TB vs the Samsung Pro 850 1TB. 16 1TB drives in a Raid 10. I am concerned about the M600's 1TB note of only a 400TB written and 219GB/day write span....seems kind of low? What is it for the Samsung Pro 1TB? I am also not sure about the difference between the v-NANDs and the NANDs and the SLCs and the MLCs, and all of that. Which one is better for a simple mix use (database/file/web servers on virtual machines)? Which actually does have a better lifespan and warranty? Thanks for your advice in advance.
  21. Ha, it is! Thanks.... The 845DC is a Sata drive? What would be the next step up? Requirement: 800GB minimum. Raid Controller is a LSI 12Gb/s controller
  22. Yes, the pro.... how does it compare to the Micron M500dc, M600, Samsung Pro 850? This will be mostly for a mix of file server, web server, mid-use database server.... again 16 drives in Raid10 I am also a bit confused by DWPD....how important is it and is 10 enough?
  23. Quick update.... after taking everything into consideration along with reading reviews from Anandtech and Techreport, I have decided to go with the Samsung 845DC 800GB....it seems to have a high PBW and solid IOPS, as well as good ready-state IOPS. Thoughts?
  24. Thanks Brian, I did consider that but I read some reports about certain Raid Controllers in Tier1 manufacturers not being able to read some 'client' drives, and also techs upport not supporting the whole system and/or voiding the warranty because the drives are in there in the first place. Sigh.
