Persyaratan sistem minimal DSpace produksi 2-3 GB memori akses acak (RAM) 1GB untuk Tomcat (misalnya "TOMCAT_OPTS =-server-Xms1024M-Xmx1024M - XX: MaxPermSize = 128M-Dfile.encoding=UTF-8") 1GB untuk Database (Oracle atau PostgreSQL). Perlu diingat sistem operasi Anda juga perlu beberapa memori untuk berfungsi. Jadi, sementara DSpace mungkin hanya perlu ~ 2GB memori, Anda harus memastikan komputer itu sendiri memiliki setidaknya 3-4GB RAM tersedia secara keseluruhan. 20 GB penyimpanan (atau kira-kira penyimpanan cukup untuk semua file yang Anda ingin menyimpan dalam DSpace)Sistem ini minimal harus mampu mendukung situs DSpace kira-kira 20.000 item atau kurang. Meskipun persis jumlah item akan tergantung pada jumlah aktivitas (pencarian, mengakses, mingguan, dll) dalam situs DSpace.Instalasi kosong DSpace secara efektif akan memerlukan kurang dari 1GB penyimpanan. Perkiraan penyimpanan sangat kasar. Jumlah sebenarnya penyimpanan Anda akan perlu tergantung pada ukuran file yang Anda berencana untuk menyimpan di DSpace. File tidak dikompresi dengan cara apapun, sehingga pada minimal Anda perlu cukup ruang untuk menyimpan semua file Anda, ditambah beberapa ruang tambahan untuk database penyimpanan dan sebuah file log. Anda juga akan perlu dipersiapkan untuk menambah ruang penyimpanan tambahan ketika Anda menambahkan konten ke DSpace.Perkiraan biaya: sekitar $599. (kira-kira diverifikasi 12/05/2012 melalui Dell - dasar R210II rak server). Sistem produksi DSpace mid-range 4 GB memori akses acak (RAM) ~2GB for Tomcat (e.g. "TOMCAT_OPTS=-server -Xms2048M -Xmx2048M -XX:MaxPermSize=128M -Dfile.encoding=UTF-8") ~2GB for Database (PostgreSQL or Oracle). Keep in mind your Operating System also needs some memory to function. So, while a mid-range DSpace may only need ~4GB of memory, you should ensure the computer itself has at least 5-6GB of RAM available overall. 200 GB of Storage (or roughly enough storage for all the files you wish to store in DSpace)This mid-range system may be necessary for DSpace sites which either have a larger number of items (roughly 50,000 or more) or a larger amount of activity (searches, accesses, downloads, etc) within the system. Again the storage estimates are very rough. The actual amount of storage you will need depends on the size of the files you plan to store in DSpace. Files are not compressed in any way, so at a bare minimum you need enough space to store all of your files, plus some extra space for database storage and logfiles. You also will need to be prepared to add additional storage space as you add more content to DSpace.High End DSpace Production system requirements: Any modern processor / CPU. (During normal function, DSpace is not very CPU heavy. However, some backend tasks which are scheduled via "cron" do require CPU. As your amount of content increases, you may need a higher end CPU.) 8GB of Random Access Memory (RAM) ~4-6GB for Tomcat ~2-4GB for Database (PostgreSQL or Oracle) Keep in mind your Operating System also needs some memory to function. So, while a mid-range DSpace may only need ~8GB of memory, you should ensure the computer itself has at least 9-10GB of RAM available overall. 1TB of Storage (or roughly enough storage for all the files you wish to store in DSpace) Storage examples: 73 GB 15,000 rpm network disks in RAID accessible over a gigabit connection for storing the database and indexes 7,400 rpm network disks in RAID accessible over a gigabit connection for storing the data whose size can be easily expanded.The high-end system should only be necessary for extremely large (500,000 or more items) or extremely active DSpace sites. The majority of DSpace sites should not require this high end system until they experience a larger amount of growth or activity.Approximate cost: around $2500.
