Uji throughput dan kinerja IOPS sistem file NAS - File Storage NAS

Topik ini menjelaskan cara menggunakan tool FIO untuk menguji throughput dan operasi input/output per detik (IOPS) sistem file di Linux dan Windows.

Prasyarat

Sistem file telah dibuat dan dimount pada Instance Elastic Compute Service (ECS). Untuk informasi selengkapnya, lihat Quick Start.

Informasi latar belakang

Metrik kinerja dalam topik ini didasarkan pada pengujian yang dilakukan pada sistem Linux dan Windows menggunakan tool FIO. Hasil ini berfungsi sebagai referensi kinerja untuk File Storage NAS. Untuk mencapai metrik kinerja resmi File Storage NAS, Anda harus menggunakan beberapa Instance ECS untuk pengujian. Untuk metrik kinerja resmi, lihat File Storage NAS.

Perhatian

Sebelum menguji kinerja, perhatikan hal-hal berikut.

Throughput maksimum tidak dapat melebihi bandwidth internal Instance ECS. Jika bandwidth internal terlalu rendah, throughput akan dikendalikan alirannya (throttled).
Sebagai contoh, jika Anda membeli sistem file NAS kapasitas tujuan umum dengan kapasitas terendah, throughput baca awalnya adalah 150 MB/detik. Jika Instance ECS Anda memiliki bandwidth internal 100 Mbps, throughput maksimumnya adalah 12,5 MB/detik. Untuk menguji hingga 150 MB/detik, Anda memerlukan minimal 12 Instance ECS. Jika Instance ECS Anda memiliki bandwidth internal 1 Gbps, throughput maksimumnya adalah 125 MB/detik. Untuk menguji hingga 150 MB/detik, Anda memerlukan minimal 2 Instance ECS.
Di Linux, client NFS membatasi jumlah permintaan NFS konkuren. Nilai default dalam kernel yang dikompilasi adalah 2, yang sangat memengaruhi kinerja. Setelah menginstal client NFS, Anda dapat memodifikasi jumlah permintaan NFS konkuren untuk meningkatkan kinerja NFS. Untuk informasi selengkapnya, lihat Bagaimana cara memodifikasi jumlah permintaan NFS konkuren?.
Di Windows, kinerja sistem file NAS protokol NFS dibatasi oleh eksekusi sekuensial permintaan untuk satu sistem file oleh client NFS Windows. Anda dapat menyesuaikan parameter -numjobs untuk menambah jumlah file dalam pengujian FIO.

Prosedur

Lakukan koneksi jarak jauh ke Instance ECS. Untuk informasi selengkapnya, lihat Connection methods.
Instal tool FIO. Jika tool FIO sudah terinstal, lewati langkah ini.
- Sistem operasi Linux
  Sistem operasi
  Perintah instalasi
  CentOS
  sudo yum install fio
  Redhat
  Alibaba Cloud Linux
  Ubuntu
  Jalankan perintah berikut secara berurutan:
  sudo apt-get update
  sudo apt-get install fio
  Debian
- Sistem operasi Windows
  Unduh paket instalasi FIO dalam format MSI dari website resmi FIO dan instal paket tersebut.
Jalankan perintah pengujian kinerja.
- Untuk perintah pengujian di Linux, lihat Perintah pengujian kinerja untuk Linux.

Pengujian kinerja di Windows

Bagian ini menggunakan sistem file NAS kapasitas tujuan umum yang dimount ke drive Z: sebagai contoh. File yang dapat dieksekusi FIO diinstal di C:\Program Files\fio\fio.exe. Jalankan perintah berikut untuk menguji kinerja.

Catatan

Saat menguji kinerja sistem file NAS protokol NFS di Windows, kinerja dibatasi oleh eksekusi sekuensial permintaan untuk satu sistem file oleh client NFS Windows. Anda dapat menyesuaikan parameter -numjobs untuk menambah jumlah file dalam pengujian FIO.

Deskripsi parameter FIO

Tabel berikut menjelaskan parameter FIO yang digunakan dalam perintah pengujian.

Parameter	Deskripsi
direct	Menentukan apakah akan menggunakan direct I/O. Nilai default: 1. 1: Menggunakan direct I/O. Ini mengabaikan cache I/O dan menulis data secara langsung. 0: Tidak menggunakan direct I/O.
iodepth	Kedalaman antrian I/O untuk pengujian. Misalnya, `-iodepth=1` berarti jumlah maksimum operasi I/O dalam satu permintaan FIO adalah 1.
rw	Kebijakan baca/tulis untuk pengujian. Nilai yang valid: randwrite: tulis acak. randread: baca acak. read: baca sekuensial. write: tulis sekuensial. randrw: baca dan tulis acak campuran.
ioengine	Mesin I/O yang digunakan FIO untuk pengujian. Biasanya pilih libaio karena lebih sesuai dengan pola aplikasi sehari-hari. Untuk opsi lainnya, lihat dokumentasi resmi FIO.
bs	Ukuran blok unit I/O. Anda dapat menentukan nilai terpisah untuk baca dan tulis dalam format `read,write`. Jika nilai dibiarkan kosong, nilai default akan digunakan.
size	Ukuran file pengujian. Ukuran file pengujian. FIO membaca atau menulis seluruh ukuran file sebelum pengujian berhenti, kecuali dibatasi oleh opsi lain seperti runtime. Jika parameter ini tidak ditentukan, FIO menggunakan ukuran penuh file atau perangkat. Anda juga dapat menentukan ukuran sebagai persentase dari 1 hingga 100. Misalnya, `size=20%` menggunakan 20% dari ukuran penuh file atau perangkat.
numjobs	Jumlah thread pengujian konkuren.
runtime	Durasi pengujian, yang menunjukkan periode waktu tool fio berjalan. Jika parameter ini tidak ditentukan, FIO terus-menerus membaca atau menulis seluruh file. Ukuran file dan ukuran blok ditentukan masing-masing oleh parameter size dan bs.
group_reporting	Mode tampilan hasil pengujian. Mode tampilan untuk hasil pengujian. Jika ditentukan, hasil menampilkan statistik yang diagregasi untuk setiap proses, bukan untuk setiap task.
directory	Jalur mount sistem file yang akan diuji.
name	Nama task pengujian. Anda dapat menyetel ini sesuai kebutuhan.

Untuk informasi selengkapnya tentang parameter ini, lihat halaman manual FIO.
