3 Skyward Supported Servers Database ServersWindows 2008 R2AIX version 5.3.x, or 6.1.x 64 BitSuSe Linux Enterprise Server 10.x, 11.x 64 BitWeb ServersWindows R2 64 Bit Server with IIS 7.5Yes - Windows Server 2012 Support Coming Soon!
4 General Server Recommendations Skyward supports Virtual Servers (VMware Partner)Skyward Servers must be 64 bit Operating SystemsSkyward Servers cannot be domain controllersGigabit network connection required for all Skyward Servers.Fiber Channel and iSCSI SAN storage are supported for Skyward DatabasesFiber Channel SAN storage is recommended for the best database performance.A separate Web server located in a DMZ is can accommodate access to webproducts outside the district.Raid 1+0(10) is best, Raid 1 and Raid 5 are supported
5 Server Virtualization Server virtualization is the masking of physical server resources, including the number and identity of individual physical servers, processors, and operating systems, from server users.AdvantagesIncreases hardware utilization by 50-70%Decreases hardware and software capital costs by 40%Decreases operating costs by 50-70%Virtualization productsVMware vSphere productsMicrosoft – Hyper-VCitrix - XENParallels

9 Why the changes in server design? More Powerful Hardware ChoicesImprovements in OpenEdge 10.2BImproved OS technology – ex. Windows 2008 R264 bit Operating System lifts database memory limitsRead data in Nanoseconds vs. MillisecondsImproved Web Application PlatformImproved Type 2 database structureImprovement in Disk Technology (SSD)
10 Improvements made in 64 Bit Improvements in Server Memory (RAM)32GB Maximum memory in 2008 R2 Standard2TB Maximum memory in 2008 R2 EnterpriseOpenEdge 10.2B Maximum memory 8TB per database!Improvements in memory means:Purchase Servers with more RAMAllocate more RAM to virtual database serversAllocate more memory to Database BuffersRun WebSpeed Brokers in Shared Memory
11 Shared Memory for Unix/Linux Currently WebSpeed in shared memory requires Windows 2008 R2.What if we don’t run a Windows Database Server?We are testing WebSpeed Shared memory configurations for Unix / Linux
12 Improvements made in 64 Bit Servers Increase I/O on the same hardware by upgrading WindowsDB restore example:2008R2 245,000 Kbs I/O2003R2 180,000 Kbs I/O35% Improvement from a windows upgrade

15 Disk StorageRemember the days when floppy disks were used to share files? Since then the Megabyte has quickly given way to the Gigabyte; or more commonly the disk storage may be measured in Terabytes.1 Megabyte*1,000,000 bytes1 Gigabyte*1,000,000,000 bytes1 Terabyte1 Petabyte*1,000,000,000,000 bytes*estimated value
16 Common Disk Drive Technology SATA stands for Serial Advanced Technology Attachment is marketed as a general-purpose successor to parallel ATA and has become common in the consumer market. It is typically a lower cost disk and may be used in a SAN successfully if I/O is spread across many disks (spindles)SAS stands for Serial Attached Small Computer Systems Interface AKA: Serial Attached SCSI (pronounced scuzzy)) . SAS is more expensive and targets critical server applications due to it’s higher throughput.SSD stands for Solid State Disks and is a data storage device that uses integrated circuit assemblies as memory to store data persistently. SSD technology uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives. SSDs do not employ any moving mechanical components
17 Common SAN TechnologyFiber Channel is a high speed serial bus intended for high end storage devices such as Storage Area Networks.iSCSI uses the SCSI protocol over a TCP/IP network. It enables any machine on an IP network to contact a remote dedicated target and perform block I/O on it just as it would do with a local hard disk.
18 What Storage Technology is the best? What can you afford?- SSD is fastest, but the most expensive- SAS is fast, but costs more than SATA- SATA works ok if spread across many drives / spindles (example: Dell Equilogic SAN uses 16 SATA drives)
19 What Storage Technology is the best? How is the technology implemented?- Fiber Channel is the fastest, but also the most expensive- iSCSI works well if implemented properly(example – Enable Jumbo Frames)
20 What is better, SAN or Local Disks? - SANs typically offers more options (Replication, Virtualization, Redundancy)SAN storage can be just as fast or faster than Local Storage if implemented properly.Local Disk Storage is easier to configure
