Altiris Tawarkan Kemudahan Pengelolaan Aset TI

Kamis, 19 Maret 2009 | 11:48 WIB

JAKARTA, Kompas.com – Hari-hari ini kian banyak perusahaan besar di seluruh dunia mengumumkan berita buruk, seperti PHK dan pemangkasan anggaran. Namun di pihak lain, peran TI terus meningkat. Maka manajemen yang baik – yang mampu menurunkan biaya secara efektif – sangat diperlukan.

Manajemen aset TI pun kian penting di masa krisis ekonomi global ini. Administrator TI harus tahu seluruh aset TI-nya, mampu mengelola aktivitas harian secara lebih sederhana, mendukung produktivitas pengguna yang lebih tinggi. Pendek kata, TI harus bisa membantu penghematan biaya dan meningkatkan nilai investasi.

Software manajemen yang cerdas, yang tidak sekadar menyajikan software, bisa dipakai di sini. Dengan software tersebut, audit software akan bisa dilakukan dengan mudah, cepat, dan akurat. Download sofware pun cuma perlu dilakukan untuk belum terpasang saja. Selain itu dapat dipastikan bahwa software tersebut tetap ter-install. Pengumpulan lisensi software saat diperlukan, juga negosiasi ulang kontrak, akan dioptimalkan demi menghemat biaya.

Salah satu software pintar ini adalah Altiris Server maupun Client Management Suite 7 dari Symantec. Mendukung Windows, Linux dan Mac, Altiris dapat mengurang konsumsi daya dengan memasukkan PC-PC ke dalam moda tidur atau hibernasi dengan menggunakan kebijakan power standar. Administrator TI akan disajikan tool penting yang memastikan uptime melalui otomasi provisioning, kontrol, dan monitoring server secara fisik dan virtual.

Fitur baru pada Suite 7 ini, kata Steven Scheurmann (Director, Enterprise OEMs, AP & Japan, Symantec Asia Pacific Pte Ltd) saat memperkenalkan produk ini di Jakarta, adalah kemampuan untuk terintegrasi dengan produk Symantec lain dalam satu platform, seperti sekuriti dan backup.

Software ini sendiri banyak dipakai oleh kalangan perbankan dan telekomunikasi, juga sektor-sektor lain. Salah satu contohnya adalah Meijer, sebuah perusahaan grosir di AS yang mengoperasikan 185 supercenter dan mengelola 10.000 desktop dan 100 server terkontrol. Menurut system engineer Dave Durkee, kemampuan otomasi Client Management Suite dan Server Management Suite telah memperbaiki proses pengelolaan patch sehingga perangkat yang ada memenuhi nyaris 100% aturan yang diterapkan.

Altiris Client Management Suite 7 ditawarkan dengan harga perkiraan US$ 95 per managed node. Sedangkan Altiris Server Management Suite 7 dibandrol dengan harga US$ 411 per managed server. Di tanah air, software yang khusus untuk server Dell sudah terbundel ini sudah digunakan oleh Holcim.

NetBackup 7 sudah diluncurkan

Monday, 15 February 2010 23:55 administrator

Symantec sudah meluncurkan versi terbaru aplikasi NetBackup tanggal 1 Februari 2010 yang lalu. Produk yang sebelumnya bernama Veritas NetBackup ini, sekarang berganti nama menjadi Symantec NetBackup.

Fitur baru yang utama adalah fungsi deduplikasi yang dapat dipilih dilakukan di media server atau pada client.
Dengan Dedupe, penghematan ruang penyimpanan pada disk dapat dilakukan untuk pengulangan backup data-data yang sama.
Pada dedupikasi yang dilakukan oleh media server, client akan mengirimkan seluruh data backup. Sedangkan jika dedupe dilakukan pada client, hanya data-data baru yang dikirimkan ke media server.
Lisensi dedupe dihitung berdasarkan besarnya jumlah data yang dibackup.

NetBackup 7 dapat diupgrade langsung dari NetBackup 6.5.4 tanpa harus menambahkan lisensi baru. Linsensi baru hanya diperlukan jika ingin menggunakan fitur barunya seperti dedupe.
Fitur lain yang dipercanggih adalah kemampuan membackup virtual machine dalam keadaan mati tanpa harus menghidupkannya. Lisensi agent mesin virtual ini adalah per server, bukan per virtual machine.

NOM dan NetBackup Reporter kini fungsinya digantikan oleh OpsCenter. Lisensi OpsCenter gratis seperti pada NOM, namun untuk kustomisasi report, diberikan lisensi evaluasi selama 60 hari seperti pada NetBackup Reporter. Fitur ini disebut OpsCenter Analytics.

Fitur baru lainnya adalah client direct yang meningkatkan efisiensi kerja NetBackup dengan mengurangi hop stream data backup tanpa harus melalui media server, melainkan langsung menuju storage.
