1 Scholastic Education Technology Programs Version 2.3.x System Requirements & Technical Overview Scholastic Achievement Manager and Scholastic Education Technology Programs The Scholastic Achievement Manager (SAM) is the learning management system and technology platform for Scholastic Education Technology programs. SAM provides administrators with the ability to implement and monitor applications on a district-wide basis. SAM also has district-wide capabilities such as district reporting, adequate yearly progress (AYP), demographic grouping and reporting, and AYP demographic filtering. For the teacher, SAM provides multiple supports for classroom management and data-driven instruction.

2 Technology Platform Scholastic Education Technology programs are built using Internet and industry-standard technology in order to provide capacity for high levels of concurrent usage and reliability. They use standard Internet components that simplify setup and optimize issues surrounding student access to servers. Clients run in standard web browsers and connect to servers over HTTP or HTTPS. Scholastic Education Technology programs require a persistent connection to a server computer hosted by the district or a Scholastic data center. This server, the SAM Server, combines the functions of an application server (running programs) with a database server (managing and storing data). Installations using more than one SAM Server at the district level may require an additional aggregation server to gather, manage, and store data from across the different SAM Servers (this is not required of districts using a Scholastic data center to host the SAM Server). Scholastic Education Technology programs use browser-based clients. This requires large media files (video, etc.) be sent to the client over the network. To reduce network congestion, Scholastic strongly recommends installing one or more Scholastic Media Accelerators (SMA) (page 9). The recommended system requirements outlined in the following sections are based on a certification process in which applications are put through a rigorous set of tests to determine their stability, performance, and compatibility with each other and with a wide variety of hardware and software environments. Scholastic lists requirements that have been tested and will be supported by Scholastic should issues arise. Noncertified configurations may be compatible with Scholastic Education Technology programs, but Scholastic cannot guarantee support for these configurations.

3 Server Requirements Local District Servers System requirements for locally installed SAM Servers: Operating System: Macintosh OS X Server through 10.9.x; Windows Server 2003 (32 bit), Windows 2008 (64 bit), Windows Server 2012 (64 bit); Novell SuSE Linux Enterprise Server 11 (64 bit); 64-bit operating systems recommended Memory: 4 GB RAM (more for higher concurrency levels) Processor: Intel Xeon dual-core (higher speed/more cores for higher concurrency levels) Hard Drive: 20 GB free for single-school servers, 200 GB for large multi-school servers Internet: SAM Servers must have Internet access Scholastic recommends multi-core Intel Xeon processors (or equivalent) operating at 2.0 GHz or better for servers. Faster processors, more cores, and more memory all contribute to the ability of the server to handle higher numbers of concurrent users and larger databases. Scholastic Education Technology programs may be installed on virtual servers using virtualization software such as VMWare ESX4.x. Resources for the Scholastic VM should be dedicated, not shared. Contact Scholastic Technical Services if planning a deployment using virtual servers. Scholastic Education Technology programs are not supported on servers using these operating systems: Windows 2000 Server, Windows NT Macintosh OS X Server 10.0 through Novell Netware, SuSE Linux Enterprise Server 9 or 10 Scholastic Education Technology programs are not compatible with Power PC Macintosh servers. For installations that serve a large number of concurrent users or 100,000+ active student accounts, additional SAM servers may be required (see Concurrency, page 6). Scholastic Data Centers Districts using a Scholastic Data Center to host their SAM Server do not require a locally installed server, but require an SMA (page 9). The hosted SAM Server uses an SSL connection to communicate with workstations. Scholastic automatically installs new programs and updates, backs up user data nightly, and stores all user data, including backups, in encrypted format. Contact Scholastic Technical Support with questions regarding server requirements. Scholastic Education Technology Programs v2.3.x Updated

Thin Client workstations are not certified or recommended for Scholastic programs. Scholastic Education Technology version 2.3.x programs support a wide range of client workstations running many different processors and operating systems. As a general rule, any workstation or laptop purchased in the last four years should be capable of running any Scholastic Education Technology program. Districts considering using older workstations should consider the following factors: Workstations, laptops, or netbooks with Intel Atom processors (or equivalent) may or may not be suitable for running Scholastic Education Technology programs, depending on the processor s version, clock speed, and supporting hardware. Scholastic recommends testing any Atom-based system with the application(s) you intend to use. Note for Districts Using Internet Explorer 8 or Windows XP: Staring with Scholastic Education technology programs version 2.3, Scholastic no longer supports using Internet Explorer 8 with its programs. Version 2.3 programs require Internet Explorer 9 or later. Windows XP does not allow users to upgrade to Internet Explorer 9. Districts using Windows XP will not be able to run Internet Explorer 9 on their workstations. Scholastic recommends using Chrome 24 or later or Firefox version 27 or later on workstations using Windows XP. Scholastic Education Technology Programs v2.3.x Updated

5 Browser Settings All workstation browsers must have the following settings enabled: Flash: Should be version 11.4 plug-in (enabled by default) and must not be disabled JavaScript: Must not be disabled Pop-Up Blockers: Must be disabled, or Student and Educator Access pages excepted Security Level Settings: Default settings supported; IE Maximum Security levels not supported Images Enabled: Default settings are supported; Image Display must not be turned off Privacy Settings: Default settings supported; Maximum Privacy Setting (disabling cookies) not supported Mixed Content: Browsers should allow mixed content (e.g., and Mobile Devices Some Scholastic Education Technology programs and components are available in mobilecompatible forms. Mobile-compatible Scholastic programs require one of the following operating systems: ios version 7.0 or later running on ipad 2 or later Android version 4.1 or later on devices with a screen resolution of 1280x800 Additionally, Scholastic programs are compatible with Samsung Galaxy 10.1 and Nexus 10 devices. See individual program documentation at the Scholastic Education Product Support website ( for information and specifications for mobilecompatible programs. Netbooks Some netbook models (laptop-format miniature computers typically configured with an Intel Atomclass processor; Windows 7, Vista, or XP; reduced local storage; 1 GB of RAM; and a small display) are able to run Scholastic Education Technology programs successfully. Other models are not compatible because of inadequate local storage, underpowered processors, or screens not capable of displaying a minimum resolution of 800 x 600. In particular, Linux-based netbooks or netbooks with a maximum screen resolution of 1024 x 576 are not suitable for use with Scholastic programs. Because of persistent reports from customers of problems with netbooks from many manufacturers, Scholastic does not recommend the use of netbooks with Scholastic Education Technology programs. Contact Scholastic Technical Support at with questions regarding specific netbooks. Scholastic Education Technology Programs v2.3.x Updated

6 Chromebooks Chromebooks are laptop computers manufactured under license from Google that use Google s own operating system, Chrome OS, and Chrome browser. Beginning with version 2.3, Scholastic supports using Scholastic Education Technology programs using Chrome OS on the following Chromebooks devices: Acer C Acer C720 Chromebook 1 HP Chromebook 11 HP Chromebook 14 HP Pavilion 14-C010us Lenovo Thinkpad X131e Chromebook Samsung E303C12 Toshiba Chromebook Scholastic recommends setting Chrome OS to the Stable channel in the Chromebook settings. On the Stable channel, Google will push out an update to Chrome OS approximately every six weeks. These updates may result in performance changes to Scholastic programs; Scholastic will issue program updates to solve issues arising from these updates. As a general rule, Chromebook devices running Chrome OS version 32 or later should be capable of running Scholastic Education Technology version 2.3.x programs. Districts using Chromebooks other than those listed here should consider that the device may or may not be suitable for running Scholastic Education Technology programs, depending on the processor s version, clock speed, and supporting hardware. Scholastic recommends testing these Chromebook devices with the application(s) you intend to use. Contact Scholastic Technical Support at with questions regarding running Scholastic programs on Chromebooks. Scholastic Education Technology Programs v2.3.x Updated

7 Concurrency Concurrency refers to the number of simultaneous users that may be logged in to a program before there is a noticeable reduction in the program s responsiveness. Concurrency is affected by many factors, including: Network bandwidth across the enterprise Bandwidth utilization Packet prioritization availability Firewall configurations Processor speed on the server Server virtualization Available memory on the server Other server settings Content filtering settings Improperly configured virus-protection software In addition, concurrency is affected by running class, school, or district reports while students are using the applications. Impact from running reports is most noticeable when running large districtlevel reports or when a server is running near full capacity from student sessions. Therefore, Scholastic recommends running reports whenever possible outside of normal class time. Local District Servers For certification purposes, Scholastic benchmarks using a Quad-Core Xeon server with 16 GB of RAM operating over a high-speed network. In this configuration, SAM is capable of supporting 700 concurrent users in Fraction Nation, 750 concurrent users in READ 180 and System 44, and 1000 concurrent users in all other applications. These benchmarks were established by simulating a district infrastructure with high-speed WAN, gigabit Ethernet switch, and 100 Base-T connections to all workstations from the servers described on pages 3-4. In testing, server performance was found to be comparable on Macintosh, Windows, and Linux servers. To achieve highest levels of performance, multiple cores and a 64-bit OS (e.g., Windows bit) are required. Scholastic Data Centers (iread and MATH 180 users) Scholastic Data Centers that host Scholastic Education Technology programs (including iread and MATH 180) are constantly adjusted to accommodate concurrent users. However, end user performance will be affected by the factors listed above, particularly bandwidth. Your district technical audit provides specific bandwidth information and recommendations. For more information on technical audits, see the Scholastic Technical Implementation Guide at the Scholastic Education Product Support website, Please contact Scholastic Technical Support at for help with selecting and tuning the SAM Server to best match your installation s product mix and expected usage.

8 Bandwidth Requirements Scholastic recommends an average of 100 kbps of bandwidth per active workstation or ipad. Average, peak, and initial bandwidth requirements vary greatly depending on the product and the usage. No matter how fast the network connection between workstation and server is, if other bandwidth-intensive activities (VoIP, streaming video, audio downloads, database backups, etc.) are running on the network at the same time, program performance may suffer. For this reason, Scholastic recommends the use of packet-shaping techniques on heavily trafficked networks. Scholastic Education Technology programs operate over TCP/IP networks including wireless ( a, g, n). When employing a wireless network, it is important not to overload the access point with too many connections, or student sessions may be dropped. Scholastic recommends using an industry-standard switched network for optimal performance. Contact Scholastic Technical Support at for specific bandwidth questions. Firewalls, Proxies, and Content Filters The following URLs should be whitelisted and allowed to pass through firewalls, proxies, and content filters: Districts with locally installed servers: IP address of the district server (on student and teacher workstations) Districts using Scholastic Data centers: [district name].*.education.scholastic.com sam-cdn.education.scholastic.com Additionally, ports 80 and 443 should be open to allow data to pass from servers to workstations. Contact Scholastic Technical Support at for additional questions regarding firewalls, proxies, and content filters as they relate to Scholastic Education Technology programs. Home Access Many Scholastic Education Technology programs offer home or other out-of-classroom access (school libraries, etc.). Consult the individual program documentation at the Scholastic Education Product Support website ( for detailed information on home access options for programs. See the Workstation Requirements for computer and browser requirements for home computers. Teachers and administrators may limit home access of programs through SAM. See Enrolling and Managing Students Using Scholastic Achievement Manager on the Scholastic Education Product Support website for more information.

9 Scholastic Media Accelerator (SMA) Media for Scholastic Education Technology programs (DVD-based media assets) must be installed on a server, not on individual workstations. In small deployments, media may be served directly from the locally installed SAM Server. Larger deployments may need to use the Scholastic Media Accelerator (SMA) to augment the delivery of large media files from the SAM Server to workstations. The SMA creates a caching server to allow for faster delivery of media over the network. It needs to be installed on a separate, locally-installed server computer. Currently, the following programs utilize the SMA: iread, MATH 180, READ 180 Next Generation, READ 180 Enterprise Edition, System 44 Next Generation, System 44 Enterprise Edition, and FASTT Math Next Generation. In addition to large deployments, Scholastic strongly recommends that districts using Scholastic Data Centers to host their SAM Server install the SMA. Districts should also consider installing an SMA if: They are in an environment with low available bandwidth and/or high concurrent usage. They wish to move media traffic off of central servers. SMA software is free from Scholastic and is included in some Scholastic Education Technology program installation kits. If you are unsure if your district needs to install an SMA, contact Scholastic Technical Services to discuss your deployment. The SMA may be installed on any computer with the following characteristics: Operating System: Windows XP SP3, Windows 8.x, Windows 7, Windows 2003, 2008, or 2012; Macintosh OS X or later; Novell SuSE Linux Enterprise Server 11 (64 bit) Processor: Pentium 4 processor 2 GHz or higher; Intel-based Mac Memory: Minimum 2.0 GB of RAM Hard Drive: Minimum 25 GB available drive space Drive Speed: 7200 rpm drive recommended Network: 100 megabit, Gigabit Ethernet recommended SMAs cannot be installed on servers running SAM software. Therefore, aggregation servers cannot double as SMA Servers. IMPORTANT: The versions of Scholastic media and SMA software must match. (e.g., version 2.3 media will not function if the SMA is using version 2.2 or earlier software. The SMA must be the same version as the media.)

10 District-Wide Deployment Options Scholastic Education Technology programs are designed for flexibility. They may be deployed using one of five basic deployment options or configurations, depending on the district s bandwidth, infrastructure, hardware CPU and memory, and the estimated level of concurrent usage. All deployments require: Student workstations in a classroom or computer lab (desktops or laptops) Teacher workstations (desktop or laptop) Depending on deployment, an SMA to offload media delivery (page 8). Districts using deployments with locally-installed SAM Servers additionally require: One or more SAM Servers networked to the workstations A data aggregation server that can receive student data from multiple SAM Servers to create district-wide reports (if aggregation is not desired, or all schools are supported by one SAM Server, no aggregation server is needed) Option A School Model (Local Application Server[s] and No Data Aggregation Server): Recommended for districts or schools that do not have high-speed infrastructures and have no desire to aggregate data. There are no district-wide reporting or data aggregation capabilities since this option does not include a data aggregation server. Scholastic Education Technology Programs v2.3.x Updated

11 Option B District Model (Local Application Server[s] and Centralized Data Aggregation Server): Recommended for districts that deploy application servers locally but also want to run district-wide reports. SAM aggregation tools may be used to consolidate data from multiple application servers into a single aggregated database at a central location. Option C Multi-School Model (Centralized Application Server[s] and no Data Aggregation Server): Recommended for districts with high-speed infrastructures that have a centralized application server capable of supporting multiple schools. Depending on concurrency, multiple centralized application servers may need to be employed. Option D Centralized District Model (Centralized Application Server[s] and Data Aggregation Server): Recommended for districts with high-speed infrastructures and multiple centralized application servers, each capable of supporting multiple schools. Data from the application servers may then be aggregated to a district-wide aggregation server. Option E Scholastic Hosted (Scholastic Data Center) Model: Scholastic Hosting Services and Scholastic Web Subscriptions use a Scholastic data center to host your applications, with workstations connecting to the data center over the Internet. There are no school or district servers (though some districts may still require one or more SMAs). This option is recommended for districts that want to eliminate the cost of installing and maintaining local SAM Servers, as well as Novell Netware districts or any district moving toward an ASP or SaaS deployment model. No aggregation server is required.
