\r\n\r\nHow much data do you have and how much storage space do you need? Are you a data hoarder? In addition and \u00a0more importantly, are you protected against data loss in case of hardware failure? Network storage is no longer just about \u00a0massive disk pools sitting on the network waiting to gobble up the vast amounts of 1's & 0's that users are feeding them. It is about simplistic management, good performance, and reliability. Seagate recently launched their line of their NAS series labeled NAS Pro. The Pro line is aimed at the higher end SOHO and small business markets. The Pro line also boasts good performance and reliability with \u00a02, 4, & 6-bay NAS units available. And with their ever evolving NAS OS, users can house up to 30 TB of data in the 6-bay Seagate NAS Pro DP-6. All of the Seagate's NAS can be ordered either with or without drives. The Seagate NAS Pro DP-6 is not meant to sit next to your TV and be a multifunction multimedia device, it is simply and for the most part, a pure network attached storage device.\r\n\r\n \r\n[sc:sponsor sponsor="Seagate" product_link="http:\/\/www.seagate.com.edgekey.net\/products\/network-attached-storage\/business-storage\/seagate-nas-pro\/" product_name="Seagate NAS Pro DP-6" product_price_link="https:\/\/shop.seagate.com\/store?Action=DisplayPage&Locale=en_US&SiteID=sgateus&id=ThreePgCheckoutShoppingCartPage" product_price="$649.99 (empty) $1999.99 (24 TB)" ]\r\n\r\n\r\n\r\n\r\nSeagate NAS Pro 6bay 24 TB\r\nSTDF24000100\r\n\r\n\r\nCapacity\r\n24TB\r\n\r\n\r\nWidth\r\n217.0mm\r\n\r\n\r\nLength\r\n235.0mm\r\n\r\n\r\nHeight\r\n172.5mm\r\n\r\n\r\nTypical Weight\r\n9010g\r\n\r\n\r\n\r\nThe Seagate NAS Pro DP-6 is designed for larger home offices and small to medium businesses, so you are not going to see flashy and fancy packaging. A very simple design with the specifications are printed on the outside of the box.\r\n\r\n \r\n\r\nOn the back of the box is a printed graphic of the back of the NAS device.\r\n\r\n \r\n\r\nThe Seagate NAS Pro DP-6 is encased in a rigid plastic frame that should keep it safe from bumps during shipping. Our unit came with six 4TB hard drives pre-installed. Seagate's NAS Pro line can be ordered with no drives. The NAS can also be ordered with drives up to 5 TB in size.\r\n\r\n \r\n\r\n\r\nA Closer Look\r\nExternally, the Seagate DP-6 is elegant and very shiny. The minimalist approach would work well in a server room or in a small office where it can be seen during the day. The drive release buttons are at the top of each of the drive caddies. Starting from the left to the right, the drive bays are labeled 1 - 6 under each of the slots.\r\n\r\n \r\n\r\nOn the front lower left of the unit is a single USB 3.0 port. Just above is the power and and one touch backup buttons.\r\n\r\n \r\n\r\nThe very top corner on the left are the menu navigation buttons. The NAS Pro 4 and 6-bay models have LCD screens that are used to access some of the system settings such as networking, storage, temperature and fan speeds. A short press on either of the buttons turns the LCD on and navigates through the menus while a long press on either of the buttons will enter the selected menu.\r\n\r\n \r\n\r\nThe backside of the Seagate NAS Pro DP-6\u00a0features a large 120mm fan to help keep the hard drives cool during use.\r\n\r\n \r\n\r\nI\/O connections on the back panel include one USB 3.0 port, one USB 2.0 port, dual Intel one Gigabit LAN ports, and the power port. Just above the top of the USB 3.0 port there is a recessed button for resetting the admin password as well as the network settings.\r\n\r\n \r\n\r\n\r\nInternals\r\nGetting the Seagate NAS Pro DP-6\u00a0apart required the removal of a lot of screws but eventually the motherboard did come out. The CPU on the Seagate DP-6 is the new Intel Atom C2338 1.7 GHz dual-core CPU. While this CPU is at a lower clock speed of the D270x, the new changes and updates in the platform should overcome the lower clock speeds. In the past on some of the older Atom based platforms, a mix of Intel and other manufactures were used to handle more than two SATA ports. The new CPU is able to provide six SATA ports, so it is all Intel in this NAS. The low power Atom CPU also means there is not a need for active CPU cooling and is cooled by a large silver colored heatsink featured in the center of the motherboard.\r\n\r\n \r\n\r\nThe backside of the motherboard features the memory slot. This side of the motherboard is extremely easy to get to without taking the whole board out. On the left side of the case, there is a panel that slides off after removing two screws and grants access to the memory slot. The Atom C2338 can support a maximum of 16 GB of ram on the single channel.\r\n\r\nThe USB daughter board features a Phison PS2251-03-Q USB 3.0 to flash controller. This is the controller board for the NASOS \u00a0operating system.\r\n\r\n \r\n\r\nThe backplane for the drives plugs into what looks like a combination of a PCIe 1x and 4x slots.\r\n\r\n \r\n\r\nThe backplane for the Seagate NAS Pro DP-6\u00a0features six drive bays for SATA only drives. According to the specifications the NAS only supports up to 5 TB drives. As larger drives come out, I am sure only a firmware upgrade is necessary.\r\n\r\n \r\n\r\nTo keep the hard drives cool, Seagate went with the Noctua NF-P12 120mm fan. This fan offers good cooling with a low acoustical noise level. At the full 1300 RPM the fan generates a noise level of 19.8dBa.\r\n\r\n\r\nManagement Web Interface\r\nOnce the Seagate NAS Pro DP-6\u00a0is connected and powered up, you'll need to log into the web interface to manage it. In your browser, simply go to the IP address of the device. In this example, it is http:\/\/192.168.4.108. Then log in with the default username and password.\r\n\r\n \r\n\r\nThe next page presents a few of the management options. For the initial set up, device manager will be selected.\r\n\r\n \r\n\r\nThe 1st \u00a0page that comes up in device manager is the overview. In a quick glance the user can get critical information on the health of the NAS, how much memory and CPU is being used as well as how many users are connected.\r\n\r\n \r\n\r\nIn order to create a storage space, a volume needs to be created on a RAID Array. To do this, go to the storage array overview menu and click on the manage link.\r\n\r\n \r\n\r\nThe first part of creating a RAID array is selecting how many disks should be included. Click on the disks to be added then click on next.\r\n\r\n \r\n\r\nSeagate offers two options when creating a RAID Array. The quick setup option doesn't allow any changes to be made and automatically selects the RAID level for you. In our examples, we chose custom.\r\n\r\n \r\n\r\nThe Seagate NAS Pro DP-6\u00a0offers a lot in terms of RAID levels. The 1st two options are Seagate's SimplyRAID options. Based on the data presented, SimplyRAID is RAID 5 and SimplyRAID dual is RAID 6. Other options include, JOBD (Just a bunch of disks), RAID 0, RAID 1, RAID 5, RAID 6 and RAID 10. RAID Levels depend on the number of disks chosen. For example, RAID 5 requires a minimum of 3 disks, if you choose only two disks on the previous screen, RAID 5 will not be available.\r\n\r\n \r\n\r\nAfter the RAID level has been selected, an option will appear asking if the volume should be encrypted. Encrypted volumes offer better security at the cost of performance.\r\n\r\n \r\n\r\nThe next page shows the confirmation of all the settings selected over the last few screens. If everything is correct. click next.\r\n\r\n \r\n\r\nFinally, another confirmation page will verify that you want to complete the action and explains that all data on the disks will be lost. Click on YES to complete the volume creation.\r\n\r\n \r\n\r\nAfter the volume is created, you can take a look at the health and specifics of the volume on the overview page. Depending on the type of RAID used, it can take a very long time for the array to fully synchronize. During the RAID 5 volume creation it took 22 hours to fully synchronize across 4 drives.\r\n\r\n \r\n\r\nThe next step is to create users unless you are going make the data available to everyone on your network. If you are an an active directory domain, you can import your users in from one of your domain controllers.\r\n\r\n \r\n\r\n\r\n\r\n \r\n\r\nNow that the volume and the users have been created, it is time to create the shares. Shares allow users to map share names to a network drive. Simply browse to the name of the Seagate device on the network in Windows Explorer and click on the folder. Right clicking gives the option to map as a network drive.\r\n\r\nThis is an extremely basic sharing technique. Following these steps should get shares on the network and the users can start using them. The Seagate NAS OS allows the administrators a very granular level of control for accessing shares based on user accounts.\r\n\r\n \r\n\r\n\r\nManagement Web Interface Continued\r\nOn the settings page, the Seagate NAS Pro DP-6's name can be changed, it can be joined to a domain, and check and install firmware updates.\r\n\r\n \r\n\r\nThe Seagate NAS Pro DP-6\u00a0offers quite a bit in terms of network services. SMB and AFP are the file and print sharing for Windows and Mac. Each service can be configured and either turned on or off. I suggest that if you are not using a specific service than turn it off.\r\n\r\n \r\n\r\nThe Seagate NAS Pro DP-6\u00a0has two 1 gigabit network ports available for use. Each can be configured on the network page. Since the NAS has two network interfaces, they can also be set up for load balancing or failover. \u00a0To use load balancing a switch that supports 802.3ad or LACP is required and must be configured on the switch. For load balancing both network interfaces must be connected to the same switch. Fault tolerance makes one network interface active and one passive. If one interface happens to fail or become disconnected, the Seagate DP-6 activates the second interface. No additional configuration or requirements are needed on the switch and the interfaces can be on different switches for fault tolerance.\r\n\r\n \r\n\r\nThe hard drives can be configured to spin down after a certain amount of time. This reduces the overall power consumption and saves the user a little \u00a0cash here and there. UPS configuration is also available on the power management page. This will allow the UPS to communicate with the NAS and shut it down in case of a power outage thus reducing the chances of data loss.\r\n\r\n \r\n\r\nThe monitoring page gives a more in-depth view of what the NAS is doing as compared to the overview page. Each CPU\/Memory process can be viewed in detail by clicking the details button on the process title bar.\r\n\r\n \r\n\r\nThe monitoring page also includes a Drive tab. This tab gives detailed health information on each drive installed in the Seagate NAS Pro DP-6. SMART status of each drive can be viewed as well as an automatic testing schedule of each drive can be configured.\r\n\r\n \r\n\r\nThe top of the menu is the quick access to other areas of the NAS. The file browser, download manager, and App manager are easily accessed here.\r\n\r\n \r\n\r\nJust to the left of the navigation menu is an additional menu that allows the configuration of direct attached storage such as drives that are plugged into the USB slots on the NAS. Shut down, restart and deep sleep modes can be activated from here.\r\n\r\n \r\n\r\nThe Seagate NAS Pro DP-6\u00a0comes with a limited number of applications that can be installed from Seagate. In the advanced menu, additional applications can be installed manually.\r\n\r\n \r\n\r\nThe Seagate DP-6 can also act as a R-Sync target for any device to use as its backup destination. Configure the source device to use the Seagate DP-6 as the destination.\r\n\r\n\r\nTesting Methodology\r\n\r\n\r\n\r\nSystem Configuration\r\n\r\n\r\n\r\nCase\r\nCooler Master Cosmos II SE\r\n\r\n\r\nCPU\r\nIntel i7 4770K\r\n\r\n\r\n\r\nMotherboard\r\nMSI Z97m Gaming\r\n\r\n\r\nRam\r\n2 GB G.Skill F3-12800CL9q DDR3-1600\r\n\r\n\r\nGPU\r\nMSI GTX 970 OC\r\n\r\n\r\nHard Drives\r\nSamsung 840 EVO 256gb SSD\r\n\r\n\r\n\r\nWestern Digital black 500 gb 7200 RPM HDD\r\n\r\n\r\n\r\nPower Supply\r\nNXZT Hale v2 1000 Watt power supply\r\n\r\n\r\n\r\nFour Seagate 4 TB NAS 5900 RPM drives were installed and used in the NAS tests.\r\n\r\nA dual port Intel network card was installed in the test system.\r\n\r\nIn our testing I used the Thecus N5550 & QNAP TS-451 to get comparison numbers against the Seagate DP-6. The Seagate DP-6 used 4 drives and 2 GB of ram. The other NAS devices use 4 GB of ram and the same Seagate NAS hard drives.\r\n\r\nNetwork Layout\r\nFor all tests the NAS was configured to use the a single network interface. One CAT 6 cable was connected to the Cisco 2960 from the NAS and one CAT 6 cable was connected to the workstation from the switch. Testing was done on \u00a0the workstation with only 1 network card active. The switch was cleared of any configuration and left in a unconfigured state. Jumbo frames was not enabled and no changes to the network interfaces was made.\r\n\r\n \r\nSoftware\r\nAll testing is done based off of a single client accessing the NAS.\r\n\r\nTo test NAS Performance we use four applications;\u00a0The Intel NAS Performance toolkit, Crystal Disk Mark, Atto Storage benchmark, and Anvil Storage utilities.\r\n\r\nThe Intel NAS Performance toolkit simulates various tasks for storage devices such as video streaming, copying files and folders to and from the NAS as well as creating content directly on the NAS. To limit caching, a 2GB G.Skill memory module was used in all tests. All options in the Performance toolkit were left that the defaults. The NAS performance test is free to download. You can pick up a copy for yourself here.\r\n\r\nTo run Crystal Disk Mark, and Anvil storage utilities, a network share was mapped as a drive letter.\r\n\r\nAll tests were run a total of three times then averaged to get the final result.\r\n\r\nRAID 0, RAID 10, and RAID 5 are all tested.\r\n\r\nTests for RAID 5 were run after the array was fully synchronized\r\n\r\n \r\n\r\nRAID Information\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nImages courtesy of Wikipedia\r\n\r\n\r\n\r\n \r\n\r\nJOBD or\u00a0Just a\u00a0Bunch\u00a0Of\u00a0Disks is exactly what the name describes. The hard drives have no actual raid functionality and are spanned at random data is written at random.\r\n\r\nRAID 0 is a stripe set and data is written across the disks evenly. The advantage of RAID 0 is speed and increased capacity. With RAID 0 there is no redundancy and data loss is very possible.\r\n\r\nRAID 1 is a mirrored set and data is mirrored from one drive to another. The advantage of RAID 1 is data redundancy as each piece of data is written to both disks. The disadvantage of RAID 1 is write speed is decreased as compared to RAID 0 due to the write operation is performed on both disks. RAID 1 capacity is that of the smallest disk.\r\n\r\nRAID 10 combines the 1st two raid levels and is a mirror of a stripe set. This allows for better speed of a RAID 0 array but the data integrity of a RAID 1 array.\r\n\r\nRAID 5 is a stripe set with parity. RAID 5 requires at least 3 disks. Data is striped across each disk, and each disk has a parity block. RAID 5 allows the loss of one drive without losing data. The advantage to RAID 5 is read speeds increase as the number of drives increase but the disadvantage is write speeds are slower as the number of drives is increased. There is overhead with RAID 5 as the parity bit needs to be calculated and with software RAID 5 there is more of a performance hit.\r\n\r\nRAID 6 expands on RAID 5 by adding an additional parity block to the array that is distributed across all the disks. Since there are two parity blocks in the array more overhead is used with a RAID 6 array.\r\n\r\nFor a full breakdown of RAID levels, take a look at the Wikipedia article here.\r\n\r\nRAID configurations are a highly debated topic. RAID has been around for a very long time. Hard drives have changed, but the technology behind RAID really hasn't. So what may have been considered ideal a few years ago may not be ideal today. If you are solely relying on multiple hard drives as a safety measure to prevent data loss, you are in for a disaster. Ideally you will use a mutli-drive array for an increase in speed and lower access times and have a backup of your data elsewhere. I have seen arrays with hot spares that had multiple drives fail and the data was gone.\r\n\r\nDo yourself a favor and read up on the different types of RAID arrays and plan accordingly. Personally, I use a RAID 10 array with an automated backup to the cloud. I feel with that setup, I've done what I can to keep my data safe.\r\n\r\n \r\n\r\n\r\nIntel NAS Performance Toolkit Results\r\n\r\n\r\n\r\n\r\n \r\n\r\n\r\n\r\n \r\n\r\n\r\nCrystal Disk Mark Results\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nAnvil Storage Utilities Results\r\n\r\n\r\n\r\n\r\n\r\n\r\n \r\n\r\n\r\nConclusion and Final Thoughts\r\n \r\n\r\n\r\n\r\nThe Seagate NAS Pro DP-6 performs well against the QNAP-TS451 with four drives installed. Yes the DP-6 has six drive bays, but I used four drive bays as the lowest common denominator to do an apples-to-apples comparison between all the NAS devices. After the initial testing, I went back and configured a RAID 0 array with all six drives and ran the tests again to see if there would be an increase in speed and there wasn't. Speeds of the 6-drive RAID 0 array were within +\/- 2% of the 4-drive array. Granted I would NEVER use a RAID 0 array with production data unless it is constantly backed up. The ever so slight lag in performance between the Seagate and QNAP in the Anvil and Crystal Disk mark tests could be attributed to the QNAP having twice the amount of ram. I tested these as they came from the factory.\r\n\r\nSeagate's NAS OS is at release 4 (at the time of this review). It is an extremely easy interface and is very quick. The simplistic approach works very well in both home and business environments. The speed in which the DP-6 can be set up is measured in just a few minutes. After unpacking the box and plugging it in, I had shares on the network in less than 10 minutes. Everything that I needed to configure in the NAS was easy to find and well labeled. The help section of the OS is very in-depth and goes into detail about the settings.\r\n\r\nOverall, I am extremely impressed with the Seagate NAS Pro DP-6. The ability to have an additional drive or two to act as a hot spare means more to me than storage capacity. I would consider myself a heavy data user with the photos and videos I take and even at 12 TB of storage capacity on a RAID 10 array, I barely scratch the surface. Production critical data is protected to a point with six drives available, but do not ever depend just on the drives as your only solution against data loss. Eventually, drives will fail.\r\n\r\nThe Seagate NAS Pro DP-6 will do well in large home offices and small to medium sized businesses. Fully loaded with six 4 TB disks the NAS tops lists right at $2000.00 but it can also be ordered empty for $649.99. These prices are a bit more expensive than the comparison NAS devices. However, the Seagate DP-6 offers two more bays. A large storage capacity, disk redundancy, and great performance all wrapped up in an attractive package tends to shoot the Seagate NAS Pro DP-6 to the top of the list.\r\n\r\n[sc:must_have_award ]
Hi Tom, I have this unit and was wondering if in your opinion the so-dimm memory module could be upgraded to a larger size? Also do you know if the stock memory is ECC?
I have this NAS, and use it for shared video editing storage with 2 editing systems. I wanted to make it work a bit faster, so I bonded the two Ethernet plugs into one “load balancing” 2Gb/s connection.
I got a Netgear GSS116E – ProSAFE 16-port Gigabit Click Switch specifically because it was able to do port aggregation.
The whole experience turned into a massive pain. I plugged the NAS into two of the switch’s ports and configured the switch to link those two ports together. It wouldn’t work. Eventually, I just tried moving the cables over to NON-aggregated ports on the switch, and the NAS popped right up on the network. I don’t know if the NAS and the GSS116e don’t have compatible port aggregation or what, but it just didn’t work. I do know that the GSS116e only does “static LAGs,” not LACP. According to the NAS’ monitoring info, it is putting out over 200MB/s (>1.6Gbps) with two plain old, unlinked gigabit ethernet ports.
So before you spend the money on a new network switch, try it out with what you have, just linking the ports in the NAS and plugging them into a dumb gig-e switch. That’s the only way I could get this to work.
