The DS1010+ can accommodate up to five internal disks to store user data. External disks (save for a special expansion unit) cannot take part in RAIDs whereas the internal ones can be used for JBOD, RAID 0, 1, 5, 10, and 6. You can specify a spare disk for RAID5 to be used if one of the main disks fails.
Recently, the manufacturer has added the Synology Hybrid RAID option. This array type is meant for inexperienced users as it is simpler to build and manage. RAID management settings are very flexible. You can change the configuration of your array, add new disks or replace the existing ones - all without losing your data. Besides, you can migrate to different hard disks without losing user files. There are some limitations, of course, but the management opportunities are very broad indeed.
Following the latest trends, the DS1010+ supports iSCSI volumes which can be created either on existing disk volumes (as files) or as new disk volumes (including those built with RAID technologies). The following features are supported: multiple LUNs, dynamic resizing of disk volumes, Windows 2008 and VMware clusters.
New in DSM 3.0, the EXT4 file system is used for data volumes. This affects the maximum permissible size of a volume as well as its performance.
You can monitor your disks via S.M.A.R.T. (and run the appropriate tests). The DS1010+ can also keep track of the temperature of the installed HDDs.
The NAS can work with all modern data transfer protocols: CIFS, AFT, FTP, NFS, and HTTP. It supports Windows domains (also as a local master browser). A recycle bin for files deleted over the network is available. The AFP protocol from Mac OS doesn’t have any special settings except for choosing a folder for the Time Machine utility. This backup tool has long been compatible with Synology's products. The DS1010+ also supports Bonjour, the network device discovery protocol used by Apple computers.
Linux users may want to access their files via NFS. Folder access rights are provided with this protocol for client IPs or IP ranges. Read-only access can be enabled. The integrated FTP server can work in passive mode, allows changing all the ports, supports encryption and UTF-8 for file and folder names, and can limit the speed and number of connections. There are two usage variants for HTTP(S): browser-based access to files (taking the user’s access rights into account) or the WebDAV protocol.
As noted above, the DS1010+ can identify users by means of Windows domains. However, when it comes to home or SOHO scenarios, it is easier to enter the user names and passwords directly in the NAS. To simplify the access rights management, users can be divided into groups. The NAS supports disk quotas for each existing disk volume. Since this is a multifunctional device, it is logical that user access to the additional services such as FTP, video surveillance, download system, etc. can be restricted, too.
Shared folders are the basic resources that users can work with. They are created on the existing disk volumes and can be encrypted with AES. An encrypted folder won’t be accessible via NFS and cannot be used for the additional services (e.g. for Download Station or media server). The encryption key can be stored on the NAS so that the folder could be mounted automatically, although this would lower the level of protection.
A new feature of the latest firmware from Synology is the support for Windows ACL to specify access rights to individual subfolders and files rather than to the parent folder only.
The NAS has two Gigabit Ethernet ports to connect to networks. You can combine them to increase the bandwidth or reliability (you need compatible network equipment for that). The DS1010+ can also connect via Wi-Fi if you plug a compatible Wi-Fi adapter with USB interface into it. If the NAS is installed in a remote location, the integrated PPPoE client may come in handy. Despite the multiple interfaces, the DS1010+ cannot serve as a router.
Besides the standard IPv4 protocol, the NAS supports the newer IPv6. For easier integration with new networks, you can establish a tunnel connection to route IPv6 to an IPv4 network. Perhaps not so crucial today, this feature may become useful eventually.
Talking about the network settings, we can also mention the DDNS client (it supports ten providers) and the option of automatic setup of the router to make the NAS’s services accessible from the Internet. Inexperienced users can get help from the integrated network setup wizard (EZ-Internet).
